Introduction
The Sink application included in the ADK provides a basis for developing Bluetooth enabled Headsets,
Soundbars and speakers. This document describes the bit field structure of the PS Keys used to configure the
application.
Note:
There are specific Configuration Tools for specific BlueCore Sink devices and it is important to use the correct
version for the device being configured.

Detailed Descriptions of Parameters
2.1.1.1.
Vref Reference Voltage Configuration
Vref Configuration - ADC Source (vref.adc.source): The Vref input can be configured to use any of the
available input sources, these being:
0 = AIO 0

1 = AIO 1

2 = AIO 2

3 = AIO 3

4 = VREF

5 = VBAT

6 = VCHG

7 = VDD_SENSE

8 = VREG_ENABLE
Note:
Not all inputs are available on all devices.
Vref Configuration - Read Period When Charging (vref.adc.period_chg ): This configures the time interval
between Vref updates in seconds while charging, 0 to disable.
Vref Configuration - Read Period When Not Charging (vref.adc.period_no_chg): This configures the timer
interval between Vref updates in seconds while not charging, 0 to disable.
2.1.1.2.
Vbat Battery Voltage Monitoring
Vbat Configuration - ADC Source (vbat.adc.source): The Vbat input can be configured to use any of the
available input sources. See vref.adc.source for the list of sources.
Vbat Configuration - Read Period When Charging (vbat.adc.period_chg): This configures the time interval
between Vbat updates in seconds while charging, 0 to disable.
Vbat Configuration - Read Period When Not Charging (vbat.adc.period_no_chg): This configures the timer
interval between Vbat updates in seconds while not charging, 0 to disable.
Vbat Configuration - Notify Interval 1 to 6 (vbat.limits[0-5].notify_period): This is an array of repeat timer
intervals used to re-send events generated by the voltage threshold array, a value of 0 results in a single event
being generated when the threshold is initially crossed. The interval time is specified in minutes, which is different
to other intervals that are all specified in seconds.
Vbat Configuration - Threshold 1 to 6 (vbat.limits[0-5].limit): Array of voltage thresholds that can be
configured to generate events when the threshold of Vbat is reached. The scaling of the threshold is (value *20)
in mV.
2.1.1.3.
Vthm Thermistor Configuration
Thermistor Configuration – ADC Source (vthm.adc.source): The Vthm input can be configured to use any of
the available input sources. See vref.adc.source for the list of sources.
Thermistor Configuration – Read Period When Charging (vthm.adc.period_chg): This configures the time
interval between Vthm updates in seconds while charging, 0 to disable.
Thermistor Configuration – Read Period When Not Charging (vthm.adc.period_no_chg): This configures
the timer interval between Vthm updates in seconds while not charging, 0 to disable.


Thermistor Drive Delay (vthm.delay): Delay in milliseconds between activating the thermistor PIO and taking
the ADC reading. This allows the voltage level to settle before the data is sampled.
Use Raw Limits (vthm.raw_limits): When set, the limit thresholds need to be entered as raw ADC counts.
When clear they need to be in mV.
Drive Thermistor PIO tick box (vthm.drive_pio): When set, a PIO is used to provide drive to the thermistor
circuit.
Limit Threshold (limits[0-6]): Up to seven limit thresholds may be configured to provide up to eight regions of
temperature based charging control. The list is ordered in ascending voltage order. The values are in units of
ADC counts or millivolts depending on the setting of vthm.raw_limits. If fewer than seven limits are specified, the
terminating value is 65535 (-1).
2.1.1.4.
Vchg Charger Configuration
Charger Settings – ADC Source (vchg.adc.source): The Vchg input can be configured to use any of the
available input sources.
Charger Settings – Read Period When Charging (vthm.adc.period_chg): This configures the time interval
between Vchg updates in seconds while charging, 0 to disable.
Charger Settings – Read Period When Not Charging (vthm.adc.period_no_chg): This configures the timer
interval between Vchg updates in seconds while not charging, 0 to disable.
Vchg Threshold (vchg.limit): Sets the USB VBUS voltage threshold. The charge current can be limited at
VBUS voltages below this level.
2.1.1.5.
Battery Notifications Configuration
Events (bat_events.event): The battery notification event array, bat_events, is an array of 6 events which are
sent (if configured) when the battery voltage level crosses the thresholds configured in the Vbat configuration
power_vbat_config.
If the battery voltage level falls below vbat.limits[0] (Threshold 1) then the event configured by Event 1 is
generated. If it rises above vbat.limits[0] (Threshold 1), then Event 2 is generated. This behaviour is the
same for all of the threshold values 1-5. Threshold 6 should be set to 0xff.
Trigger Source (bat_events.sources): The notification events can be configured to be sent during one or
several of the following operating modes:
2.1.1.6.

Bit[0]: automatic sending of event

Bit[1]: event sent on user requested battery level read

Bit[2]: event sent on initial battery level reading
Charger Configuration
The charger configuration consists of an array of eight possible charger configuration entries, each entries
contains the following parameters:
charger (Charge): Set to use this entry to control the charger

Application Note
Drive Thermistor PIO (vthm.pio): when the Drive Thermistor PIO is set, this parameter sets the PIO required to
be driven when a thermistor reading is taken.
boost (Boost): Boost charging can be disabled or set to internal or externally controlled boost if the device and
firmware revision supports it.

0 = Disabled. Boost mode is disabled.

1 = Internal. Internal boost mode is enabled on supported devices.

2 = External. External boost mode is enabled on supported devices.
Note:
Vsel (vsel): The voltage source for the IC can be set to CHARGER or Vbat.
Power Off (power_off): When checked the Sink will reduce to the minimum power consumption possible. Useful
for powering off the device at certain temperatures.
Disable Leds (disable_led): When set the LEDs are disabled while charging.
Current (current): Charge current specified in mA.
Type (sink_vterm): CSR8600 range of devices can use voltage type which allows the user to specify the exact
voltage cut off for charging, the BlueCore5 range of ICs use trim type whereby a small trim value may be applied
to the present voltage cut off value:

0 = Default

1 = Voltage

2 = Trim
Trim (trim): End of charging trim voltage adjustment value for use on BlueCore5 range of devices
Voltage (voltage): End of charging cut off voltage value for CSR8600 range of devices. The scaling of the
threshold is (value *20) in mV.

Table 2.8: PSKEY_USR6 –Timers and Counters
2.6.1.
Description of Timers and Counters
Automatic Switch Off Time (AutoSwitchOffTime_s): The time in seconds after which the Sink switches off if
not connected. If set to 0 then the Sink remains on indefinitely.
Auto Power On Timeout (AutoPowerOnTimeout_s): The value in seconds that the Sink waits in the limbo
state for a power on event before powering off. The limbo state is entered when the device is powered or
receives a power off event.
Network Service Indicator Interval (NetworkServiceIndicatorRepeatTime_s): The time in seconds after
which the network service indication is replayed if there is no network present in the connected AG.
Disable Power Off After Power On Time (DisablePowerOffAfterPowerOnTime_s): The time after Power On
for which the Power Off event has no effect. This is used for example, if the UI specifies that a long press on
Power On enters pairing mode but a long press at any other time (including in the connectable state) should
Power Off the Sink.
Paring Timeout (PairModeTimeout_s): The time in seconds that the Sink remains in the connectable /
discoverable state (pairing mode). Setting this to 0 results in the Sink entering and immediately exiting
discoverable mode, with the result that the device cannot be discovered.
If the Sink is to always be discoverable while not connected, then the feature bit Automatic Pairing Mode Enable
(see PSKEY_USR15, section 2.13) should be used in conjunction with this timeout.
Mute Reminder Interval (MuteRemindTime_s): The time between mute reminder updates. This is used for LED
and Tone reminders to indicate that the Sink is muted.
Connectable Timeout (ConnectableTimeout_s): Specifies the amount of time the Sink remains connectable
following a successful connection when using multipoint operational modes before not being connectable any
more.
Pairing Mode Timeout if PDL is Empty (PairModeTimeoutIfPDL_s): Zero to disable, if set to a non zero value
this is the pairing mode timeout value if the PDL is completely empty, if the PDL is not empty the
PairModeTimeout value is used instead.

Application Note
Type
Max Number of Reconnection Attempts (ReconnectionAttempts): This specifies the number of reconnection
attempts following an establish SLC event, or automatic reconnection event, if set to 0 and the reconnection
action is set to „LIST‟ the PDL will be traversed once only, if this value is set to 100 for example the PDL will be
traversed for 100 connection attempts.
Note:
The encryption is only refreshed when no SCO link is open, i.e. there are no active calls. If the timer expirers
when there is an active call, no action is taken and the timer is rescheduled for another timeout period.
Inquiry Timeout Period (InquiryTimeout_s): This is the timeout value for RSSI initiated pairing.
Role Switch After Connection Delay (CheckRoleDelayTime_s): Unused in the ADK.
Second AG Connection Delay Time (SecondAGConnectDelayTime_s): This value determines the delay time,
in ms, between the connection of AG1 and the start of connection to AG2 when using multipoint mode of
operation. This value may be changed from its default value if interoperability issues are seen with certain AGs.
Missed Call Indicator Interval (MissedCallIndicateTime_s): The Sink applications include a Missed Call
feature. This sends an EventMissedCall event when the Sink has seen an incoming call that did not get
answered before being terminated at the remote end, this event is repeatedly sent if the
MissedCallIndicateTime timer value is set to a non-zero value and repeats at the interval set by this
parameter.

Tri Colour LED Information
PSKEY_USR7 is used to define the PIO or LED attached to any tricolour LEDs. Once defined, tricolour LEDs can
then be passed into LED Filter Configuration (PSKEY_USR18), LED Configuration (PSKEY_USR20) or LED
Event Configuration (PSKEY_USR22) to achieve different colours e.g. Red + Blue to give Purple.
A bitmask is used to specify the PIO/LED attached to the Tricolour connection pins:

Table 2.11: PSKEY_USR10 - Button Translation Configuration
The Sink has 18 logical inputs that can be assigned physical inputs. The Sink inputs are configured as input 0 to
15, VREG(16) and CHG(17).
Input Number (button_no): The input number to be assigned.
Input: The input is split into input_source D[7:6] and input_number D[5:0]
input_source: The type of input source:

0 = PIO

1 = CAP SENSE (for CSR8670)

2 = RESERVED

3 = RESERVED
To map input 0 to a button attached to PIO 19 a configuration word of 0x0013 is used where 00 is the input
being configured and 13 is the PIO chosen for this input.
To map input 0 to cap sense input 1 a configuration word of 0x0041 is used where 00 is the input being
configured and 41 is the cap sense chosen for this input.
While it is possible to use up to PIO31 for a button input it may be necessary to configure the chosen PIO to be
useable as a general purpose I/O line which can be done through the set map pins configuration word in
PSKEY_USER4. PIO pins 0 to 12 do not need mapping for general I/O use, some additional higher number PIO
pins also do not need mapping, see the device datasheet for details of which pins are multiplexed with other
functions.

This forces the Sink to Enter Discoverable mode (pairing) if the paired device list is less than the entry.
An entry of 2 would mean that if the Sink has previously paired with either 0 or 1 devices, then the Sink enters
discoverable mode.
Bits = 1 - 7: Feature enabled.

Bits = 0: Feature disabled.
Do Not Go Discoverable During Link Loss (DoNotDiscoDuringLinkLoss):

Bit = 1: The Sink does not enter discoverable mode if a link loss event has occurred.

Bit = 0: The Sink enters discoverable mode after the link loss event.
BT2.1 Man in the Middle (ADK Only) (ManInTheMiddle):

Bit = 1: Bluetooth 2.1 man in the middle enabled.

Bit = 0: Feature disabled.


Bit = 1: Ensures that encryption is used on SLC Establishment.

Bit = 0: Encryption not enforced.
UseLowPowerAudioCodecs (UseLowPowerAudioCodecs):
Setting this feature bit will result in the Sink using the low power audio codec options to help reduce Sink power
consumption.
Play Vol Tone on Remote Indication (PlayLocalVolumeTone):

Bit = 1: The Sink plays a tone when the volume is changed using the remote device i.e. the AG.

Secure Pairing Mode Enable (SecurePairing):
This bit enables secure pairing mode. If set, then the Sink only accepts pin code requests when in pairing mode
(connectable/discoverable state). This prevents a remote user from pairing with the Sink without the Sink being
specifically placed into pairing mode.
This is over-ridden if the Sink initiates the connection. i.e. if a Sink attempts to connect to a remote AG without
the correct link key (or has the bdaddr but not the link key) then the Sink will accept a pin code request.

Bit = 1: Enables Secure Pairing.

LED Filter Configuration
The Sink application allows each Sink state/event to be associated with a unique LED flashing pattern. See
section 2.19 and section 2.19.
In addition, the software allows filters to be applied to individual LED patterns to change them in response to
some event or change in state. For example, to change the colour and/or frequency of a pattern being displayed
when the battery is low.
Two PS Keys hold the configuration details for implementing LED filters:

USR9 (word 3): Specifies the number of filters (entries) defined in PSKEY_USR18.


Note:
This is specified as an offset of 0x6000 i.e. to specify the Power On Event (0x6001) the value of this field
would be 0x01.
Speed: The multiplier/divider applied to the frequency pattern.
Note:
To leave the frequency of the original pattern unchanged this bit field should be set to 0.
Active: This bit field enables and disables the filter:

Bit = 1: Enabled.

Bit = 0: Disabled.
Unused: Dummy bit.
Speed Action: This field specifies the action to apply to the frequency:

Bit value = 01: SPEED_MULTIPLY, multiply the frequency by the value specified in the Speed field.

Bit value = 00: SPEED_DIVIDE, divide the frequency by the value specified in the Speed field.

Application Note
When implementing a filter it is normally necessary to create two filters, one to enable the change when the
trigger event or state change occurs and one to disable the change when trigger condition ceases.
Colour: This field defines the colour filter to apply:

Bit value = 0000: Reserved

Bit value = 0001: LED_A, force use of LED_A

Bit value = 0010: LED_B, force use of LED_B

Bit value = 0011: Alternating, force use of alternating LEDs

Bit value = 0100: LED_BOTH, force use of both LEDs
LED To Use: This field is used to specify an LED, used for either the Override or LED Follower behaviour, if they
are activated.
Override LED Active: This field is set to activate or deactivate the Override LED field. When activated the LED
specified in the Override LED field will be turned ON during the OFF period of the original pattern.

Bit = 1: Activate

Bit = 0: Deactivate
Unused: Dummy bits.
LED Follower Active: When this bit is set the LED specified in the Override LED field repeats the original pattern
with a time offset as specified in the LED Follower delay field.
LED Follower Delay (x50 ms): The value in this field defines the time offset in ms, between the original pattern
flashes and follower pattern flashes.
Note:
The software multiplies the value entered by 50 ms before it is applied.
Unused: Dummy bits.
Example
To configure filters to change all indications from Blue to Red on the BlueCore4-Headset development board
when the low battery event is received the PS Key hex values would be:
USR9 (word 3) = 0003 (indicating 3 filters in PSKEY_USR18)
USR18 = 1a00 8200 0000 1e00 0100 0000 1f00 0010 0000
Note:
All State and Event Indications that this filter is to affect need LED_A (blue) and LED_B (red) bit fields set in

Word 1
Sink State: System state associated with the LED pattern being defined, see Appendix B.
On time, Off time, Number of flashes and Repeat time values:
Dimming LEDs: Dimming LEDs can be enabled by entering a value in the LED Dimming field. This value is the
time between ramp steps to use.
There are 16 ramping steps used to Dim on or off an LED. It is important to ensure that the (Dim time * 16) is less
than the on time /off time for the ramp to complete.
For example, for a 1 second on 1 second off pattern, then a good Dim time to use is:
800 ms / 16 = 50 = 0x32
Time out: This field specifies the number of times the sequence, specified by the entry, will repeat (unless
superseded by another event) before it times out. When set to 0 the sequence will not time out.
LED_A: This field is a bitmask that specifies the PIO that is referred to in the PS Key attributes as LED_A.

Specialist Use of PSKEY_USR22
PSKEY_USR22 can be used to configure two other useful behaviour patterns:

Non-repeating patterns

To configure a PIO as an output pin for the duration of an event
Non-repeating Patterns: Setting the Repeat Time to 0 defines a non-repeating pattern. When a non-repeating
pattern has completed the previous state pattern will resume.

Application Note

Configuring a PIO as Output Pin: A PIO can be configured as an output pin, set and unset on individual events.
Note:
This is generally used to indicate an event.
To configure a PIO as an output pin:
Setting the Number of Flashes to 0.
2.
Set a non-zero On time to set the pin to ON (set high) or set a non-zero Off time to set the pin to Off
(set low).
Note:
Two PS Key entries must be configured, one to set the pin high when the event occurs and one to set the pin
low when the event is no longer occurring.
As with normal Event Configuration the LED_A, LED_B and Colour fields can be used to configure the ON and
OFF conditions to influence one or two PIOs.
For example to set two pins PIO[11] and PIO[12] to high when an EventChargerConnected event is
generated, the hex value entered would be:

2.20. Event Configuration
Each Sink system event is configured to be triggered by a set of system attributes. These include PIO lines, PIO
Duration and Sink State. A system event is only be generated when all the specified attribute conditions are
satisfied.
PSKEY_USR23, PSKEY_USR24 and PSKEY_USR25 are used to configure events. The keys are of fixed length
and must be 75 words long. Each key can contain a maximum of 25 Events = 75 Words.
If the key contains less than the full 25 events then the remainder of the key must be padded with zeros.
Each event is defined in the following format:

PIO Mask: The PIO mask is used to specify the PIO or PIOs that must be held high (pressed) to generate the
event:

Bit = 1: PIO must be pressed to generate event.

Bit = 0: PIO not involved in generating the event.
For Example:
To define a simultaneous press of both PIO[0] and PIO[1] to generate the event, the value for the PIO Mask bit
field would be 0x0003.
Note:
The other attributes specified in the Event System key i.e. PIO Duration and Sink State Mask conditions
must also be met for the event to be generated.

0x00 to 0x38
(3)
(1)
This is the number of the event as an offset of 0x6000, see Appendix A.
The value 0xff is used to associate the tone used as the Sink‟s Out of Band Ring Tone, see example below.
(3)
This represents the range of currently available tones, see Appendix B.
(2)
Table 2.45: PSKEY_USR26 – Tone Configuration Bit Fields
Example:
To define an Out of Band Ring Tone (Valkyries):
Event = 0xff, Tone = 0x1d
To define tone Short 5 to be played on EventPowerOn:
EventPowerOn = 0x6001 = 01, Short 5 = 0x06
Therefore the PS Key hex values required to implement these tones would be:
PSKEY_USR25 = 0002 (indicates that there are two entries in PSKEY_USR26)
PSKEY_USR26 = ff1d 0106
2.22. Power Table Setting
PSKEY_HFP_POWER_TABLE contains the power table used by the HFP library for any connections made. It
allows the link policy and the role switching implemented by the HFP library to be configured.
The power table supports entries for four modes:

Normal connected: Connected with no active SCO or A2DP links.

SCO connected: Connected with an active SCO link.

A2DP connected: Connected with a signalling channel open.

A2DP Streaming: Streaming audio.
The first word of the entry defines the number of entries for the Normal and SCO power table with a role for each
mode. The bit fields of the first word are defined as:

Application Note
In RSSI Inquiry mode the Sink attempts to find a device of the specified Class of Device in the vicinity (i.e. within
the specified RSSI thresholds) and to pair and connect to it. The Sink inquires until it successfully pairs and
connects with a device, or until it timeouts.
Description of Parameters
Inquiry Tx Power (tx_power): The inquiry transmit power used. See
HCI_Write_Inquiry_Transmit_Power_Level command in the Bluetooth Specification v2.1 + EDR.
RSSI Threshold (threshold): The peak RSSI value that any discovered device‟s RSSI value must exceed to be
considered a suitable in-range device.
If two devices are found with RSSI values that do not differ enough, the Sink continues to inquire for other
devices until it timeouts.
The difference between a discovered device's RSSI value and the RSSI Threshold must exceed this value in
order for the Sink to be considered a suitable in-range device.
Class of Device (cod_filter): Defines the Class of device that the inquiry looks for. Class of Device Filter values
are detailed in the Assigned Number document available on the Bluetooth SIG website.
Connection Threshold (conn_threshold): Defines the peak RSSI value that any device's RSSI value must
exceed to be connected to automatically, using the RSSI auto connection feature.
Connection Difference (conn_diff_threshold): Defines the difference in RSSI values returned by two devices
before the stronger device is considered suitable for the auto connection feature.
Number of Results (max_responses): Specifies a limit for the number of devices found during an inquiry
search, if 0 value there is no limit on the number of devices found.
Inquiry Timeout (timeout): Specifies the maximum inquiry time for device searching, in units of 1.28 seconds.
Number of Results (num_results): Specifies the number of results from a search that are stored.
Connect if in PDL (connect_if_in_pdl): When set this feature will prevent the connection to any device that is
not currently in the Sink paired device list.
Don’t pair if in PDL (dont_pair_if_in_pdl): When set, this feature prevents the Sink from trying to pair to a
device that has been previously paired to the Sink and is currently in the PDL.
Try all discovered (try_all_discovered): When set, this feature forces the Sink to attempt to pair/connect to the
entire list of devices it found during a search.
Start rssi pairing on PDL reset (pair_on_pdl_reset): when set, the Sink will start RSSI pairing automatically if
the paired device list is erased.

In addition to the charger configuration there are some more general USB features, these are:
USB Audio Always Routed (audio_always_on): When set the USB audio is routed even when it is not in use.
Plugin Type (plugin_type): Sets the number and type of channels being used for audio routing:
0 = usb_plugin_stereo
1 = usb_plugin_mono_nb
2 = usb_plugin_mono_wb
(stereo)

(wideband)
Plugin Index (plugin_index): Specifies the DSP plugin used, e.g. No DSP, CVC 1 MIC etc.
Attach Timeout (attach_timeout): If after attaching the USB it does not enumerate within the attach timeout the
Sink will set low power boot mode.
Deconfigure Timeout (deconfigured_timeout): If the USB becomes deconfigured and no further action is
taken within the deconfigured timeout period the Sink sets to low power boot mode.
