After the notification, buzzer would stop beeping and together with all LEDs start
to be controlled based on defined scenario.
5
In-Car Trigger Test UI
A Win32 software program, In-Car Trigger Test UI, is designed to dump the status of InCar Trigger via UART interface at run-time.
5.1 Hardware setup
5.2 Software setup
Make sure the COM interface is successfully reorganized in device management
of the connected Host PC and identify the its COM port index after setting up the
connection descript in section 5.1
Launch the executable of In-Car Trigger Test UI (InCarTriggerTestUI.exe) to bring
up the user interface of this utility program.
The Test UI contains the listed window segment divided by group box:
A. Connection window
Includes the UART interface configuration box to setup the serial connection
to In-Car Trigger.

select the baudrate to 115200 then click connect icon.
Once successfully setup the connection to In-Car Trigger, Test UI will first update
the firmware version information of In-Car Trigger in In-Car Trigger Status window.
If the connection to In-Car Trigger is fail to set up, an error window would pop-up
to notify the connection failure.
The rest functions provided with In-Car Trigger Test UI would be introduced
separately in following chapters together with related In-Car Trigger functionality.
6
Digital IO
6.1 Input
In-Car Trigger provide 3 digital input on Digital IO connector of IO/CAN pigtail to
connect and monitor the listed digital signals on patrol car:
 Ignition
 Auxiliary
 Light bar
All these three digital input could sustain 8V ~ 30V input voltage and controller of
In-Car Trigger would determine the digital input as logic high level while apply
voltage with this range.
AUX LED and Light bar LED of In-Car Trigger will be turned on if the input voltage
level on corresponded digital input is pulled high.
Also, the In-Car Status window on Test UI will keep updating the digital input
status on correspond radio icons. Icon will be set if the voltage level on the
corresponded digital input signal is pulled high.
6.2 Output
In-Car Trigger provide the listed digital output, which is connected to the BWC on
BWC slot, 2nd BWC dock, or peripheral device on patrol car.

DOUT: Turn on/off (short/open) the connection between the relay’s A/B pin on



DOUT and VBus_BWC is could be directly controlled by the UART connected host
device. Test UI also provides checkbox in the In-Car Trigger Ctrl window,
Clicking/unclicking these checkbox of corresponded digital output signal and
clicking “set” icon to control the output state.
VBus_2nd and CB_2nd output is controlled based on the status of ignition input.
These two output signal will be automatically pull high if state of ignition input is
considered as logic high.
All Digital output status will be periodically updated on In-Car Trigger Status
window of In-Car Trigger Test UI.
7
NFC
NFC reader is implemented within In-Car Trigger to retrieve the Bluetooth MAC address
and user defined data from the NFC tag implemented within BWC for triggering the
Bluetooth pairing between In-Car Trigger and BWC (refer to chapter 8 for detail
description about Bluetooth pairing)
The NFC read/write communication between In-Car Trigger and BWC follows ISO
14443A protocol.
7.1 NFC Tag information
Storage of Each BWC’s NFC tag contains the listed data which is programmed
individually at manufacturing:
 Bluetooth MAC address
A 6 bytes length unique MAC address of the Bluetooth module within the BWC.
When performing NFC sensing with In-Car Trigger, it will be retrieved by In-Car
Trigger to initiate Bluetooth pairing.
This 6 bytes address is programmed in specific offset within the storage of NFC tag
and is not wrapped with standard NFC Data Exchange Format (NDEF). NFC
reader other than In-Car Trigger might unable to retrieve or parsing this data
successfully out from NFC tag of BWC.

User Data
A data space is preserved in NFC tag to store a user self-defined max 32 bytes
length string. When performing NFC sensing, In-Car Trigger follow the Plain Text
record format with “en” IANA language code specified defined within NDEF to
parse out this 32 bytes user data from the retrieved raw data and buffer it for the
connected host device’s usage.
By following the same NDEF Plain Text record format, NFC reader other than InCar Trigger also could read/write this user data on BWC’s NFC tag.
7.2 NFC sensing
[Note]
The internal power supply of NFC reader is controlled by Ignition digital input.
Make sure 8V ~ 30V is applied to the Ignition on digital input connector of IO/CAN
pigtail before using NFC sensing function.
Approach the sensing area of NFC tag of BWC to the sensing area NFC reader
sensing area of In-Car. This behavior will make NFC reader start to retrieve information
programmed in NFC tag.
If NFC reader successfully receive the programmed information on NFC tag, pairing
notification on buzzer will be triggered and Bluetooth pairing procedure will start which
will be introduced in section 8.1. The retrieved tag information will be updated to the
BWC Status window of Test UI.
If NFC reader fail to parse the retrieve data from NFC tag (EX. the programmed user
data doesn’t following NDEF Plain Text format), The Buzzer would generate 1 long
beeping to notify user sensing fail.
7.3 NFC tag programming
Besides retrieve the data from NFC tag, the NFC reader of In-Car Trigger could be
used to program the Bluetooth Mac address and user data into the BWC’s NFC tag.
7.3.1
Bluetooth Mac address programming
The unique BT address of each BWC could be looked up in the TF card storage of
BWC. Connect the BWC to a PC with USB cable and wait for the PC identifying
the FOUCS-X1 storage in files manager.
Opening the hci_config.dump with text editor under FOUCS-X1 storage could
get the unique BT address of this BWC.
In BWC Ctrl window, click the NFC Tag BT Addr. Prog. icon, assign value into BT
Address column, and click “Set” button. Wait for the radio button indicator NFC
Tag Prog. EN and BT addr. Prog. EN being set by In-Car Trigger fixture itself to
switch the NFC reader to programming mode. The following diagram example set
the NFC reader the program the NFC tag with the listed info:
Approach the BWC NFC tag to the sensing area of the NFC reader on In-Car
Trigger fixture like section 7.2. The buzzer on fixture would generate 3 short beeps
to notify programming complete.
7.3.2
User Data programming
In BWC Ctrl window, click the NFC Tag User Data Prog., fill max 32 characters in
User Data column, and click “Set” button. Wait for the radio button indicator NFC
User Data Prog. EN being set itself to switch the NFC reader to programming
mode.
Approach the BWC NFC tag to the sensing area of the NFC reader on In-Car
Trigger fixture like section 7.2. The buzzer on fixture would generate 3 short beeps
to notify programming complete.
7.3.3
Resume NFC reader to reading mode
Un-click the NFC Tag User Data Prog. and NFC Tag BT Addr. Prog., click Set
icon and wait for NFC User Data Prog. EN and NFC BT Addr. Prog. EN being
un-set to bring the NFC reader out of programming mode.
8
Bluetooth
In-Car Trigger and BWC adopt Bluetooth Low Energy (BLE or Bluetooth 4.0) as the
wireless communication interface between each other. Comparing with Bluetooth 2.1
technology, BLE has the listed features:
 Ultra-low power consumption
The BLE maintain the connection between two paired device via a periodically
handshake mechanism instead of sustaining the link continuously, it save the
power to diving the RF component enormously to raise the operating time of BWC.
 Low data rate
As a side effect to the periodically handshaking, data transmission between 2
paired devices is not streaming but only small amount periodically. BLE is only
suitable for transferring self-defined remote command but not used to streaming
the video or audio.
8.1 Pairing decision
In-Car Trigger and BWC must perform Bluetooth pairing to setup the Bluetooth
connection, which is trigged by NFC sensing introduced in section 7.2
In Bluetooth pairing procedure, In-Car Trigger first retrieve BWC’s Bluetooth Mac
address via its NFC reader from the NFC tag of BWC, and then it decide to setup
Bluetooth connection to this BWC base on the defined pairing decision.
In-Car Trigger max support pairing to 2 BWCs with Bluetooth simultaneously, the
pairing decision is designed to which one of these Bluetooth channels will be
allocated for the new-paired BWC, and which BWC will be dis-paired if required
base on the following description of scenario:
A.
The Bluetooth mac address retrieved from NFC tag of target BWC will be
compared with the mac address currently paired with both of two Bluetooth
channels. If the address is match, this corresponded Bluetooth channel will be
allocated to pair with the target BWC.
B.
Continues from (A). If the mac address mismatch to both of the two Bluetooth
channels, the channel which status currently is not connected to its paired
device will be allocated to pair with the target BWC.
C.
Continues from (B). If both Bluetooth channels’ status currently are not
connected, the Bluetooth channel which is the last allocated for pairing will be
reserved, and the other one will be allocated to pair with the target BWC.
D.
Continues from (B). If both Bluetooth channels’ status currently are
connected, the one that its paired BWC currently is not recoding will be
allocated to pair with the target BWC.
E.
Continues from (C). If both BWCs currently paired with In-Car Trigger is
recoding, the target BWC is not allowed to pair with In-Car Trigger.
F.
Continues from (C). If both BWCs currently paired with In-Car Trigger is not
recoding, the Bluetooth channel which is the last allocated for pairing will be
reserved, and the other one will be allocated to pair with the target BWC.

In the scenario (B), (C), (D), and (F) above, The buffered BWC mac address
paired with allocated Bluetooth channel will be overwrite by the one of target
BWC, and the original BWC should be re-paired to In-Car Trigger if it want to
setup the Bluetooth connection to In-Car Trigger again.
8.1.1
Pairing / Forbidden pairing notification
Once the Bluetooth channel is chosen to be allocated to pairing with target
BWC, In-Car Trigger will generate a pairing notification to notify user it is
starting to setup the Bluetooth connection to the target BWC.
Pairing notification includes:
 Buzzer beeping. Depend on it is Bluetooth channel#1 or #2 allocated to
pair with target BWC. Buzzer will generate one or two short beeping.
 BWC Bluetooth Status LED flashing. Depend on it is Bluetooth channel#1
or #2 allocated to pair with target BWC. BWC1 or BWC2 LED will start
flashing until the Bluetooth connection is successfully setup.
After generating the pairing notification, BT Address and User Data in BWC
Status window of Test UI would be updated to the value received form NFC
during the sensing. Value of GAP Status would switch between “STARTED”
and “SCANNING” periodically.
Regarding of case (E) of pairing decision, if status of both Bluetooth channels
of In-Car Trigger is currently connected and the both paired BWCs are
recording, In-Car Trigger will generate forbidden pairing notification to notify
user pairing is not allowed currently.
Forbidden pairing notification includes:
 Buzzer beeping. Buzzer will generate one long beeping.
 BWC Bluetooth Status LED un-change. BWC LEDs will remain the
original status.
8.2 Bluetooth link establishing
After In-Car Trigger generate pairing notification, normally it would take less than 4
seconds to set up the Bluetooth link to the target BWC within 2m light-of-sign
distance.
Depend on it is Bluetooth channel#1 or #2 allocated to pair with target BWC.
BWC1 or BWC2 LED will stop blinking and turn solid on when link is successfully
established.
Value of GAP State in BWC Status window of Test UI would be switch to
“CONNECTED” when Bluetooth link is established.
8.2.1
Bluetooth service discovery and bonding
After establishing the Bluetooth link, In-Car Trigger would discover the service
of connected device and make sure it provide “BWC Service” for identifying it
is actually a BWC device.
During the discovery, value of GATT State in BWC Status window of Test UI
would update and display the service discovery state until the displayed value
keep switch between “Read Status” and “Write Ctrl” which indicate the service
discovery complete.
Once complete service discovery, In-Car Trigger would make bonding to this
BWC by storing its connection info into EEPROM and automatically try to
resume the connection at connection lost or power reset until it is paired to
another BWC.
8.2.2
Bluetooth transmission distance
Transmission distance between BWC V4 Hardware….(TBD)
8.2.3
Bluetooth link disconnecting
The Bluetooth link between In-Car Trigger and BWCs would be disconnected
due to the following reason:
1. Low signal or signal blocking
Pull the BWC faraway than defined transmission distance or block the
radiation signal with metal case would decay the Receive Signal Strength
Indicator (RSSI), which will make the Bluetooth link un-stable or even
disconnected.
The link would be re-established when the RSSI raise again due to the
distance between In-Car Trigger and BWC getting closer (within TBD m)
or signal is un-blocked.
2.
New pairing
Perform Bluetooth pairing on the target BWC with other In-Car Trigger or
pairing other BWC to the In-Car Trigger which the target BWC currently
paired with would make the original Bluetooth link between target BWC
and In-Car Trigger be replaced and destroyed.
Refer to pairing decision descript in section 8.1 for all possible condition
which the link would be replaced by a new pairing. Once the link is
replaced, it won’t recover itself unless perform Bluetooth pairing on the
BWC and In-Car Trigger again.
Depend on it is BWC1 or BWC2 disconnected from In-Car Trigger, BWC1 or
BWC2 LED would turn off.
Value of GAP Status would switch from “CONNECTED” to between
“STARTED” and “SCANNING” periodically. And Value of Disc. Code would be
updated with the code of reason of the last disconnecting.
8.2.4
Connection diagnose
This section descript some methods to diagnose the situation of failing to
establish Bluetooth connection between In-Car Trigger and BWC.
1.
Scan BWC’s advertising signal
The first step to make diagnose on failing to establish Bluetooth
connection is to check whether the BWC (serve as the Bluetooth
Peripheral device) could generate advertising signal for the In-Car Trigger
(serve as Bluetooth Central device) to make connection request.
A Smartphone support Bluetooth 4.0, with a free Android App
Bluetooth LE Scanner or other Bluetooth 4.0 specific App could be
served as a simple Bluetooth sniffer.
Launch the Bluetooth LE scanner to bring up the user interface.
Press “Scan” icon to start scanning all advertising signal generated from
Bluetooth peripheral devices nearby.
On the display list of found devices, check if the BT address of the target
BWC (refer to section 7.3), EX. 44:2C:05:27:7C:9F, is discover or not.
2.
Check the context of advertising
If the target BWC could generate advertising signal, the next step is to
check the advertising data contain the correct Service UUID for In-Car
Trigger to make connection request.
Click the device with correct BT address to display its advertising data,
and make sure the service UUID, FFA1, is contained in the advertising
data.
3.
(TBD)
8.3 BWC remote polling
Once the Bluetooth link is established between In-Car Trigger and BWC, In-Car
Trigger will periodically poll and retrieve the listed BWC status information via
Bluetooth:
 RSSI:
The receive signal strength from paired BWC.
 Operating status
Indicate the paired BWC is recording or not.
Base on the raw data of retrieved BWC status, Test UI will periodically update the
value of BWC status information listed above in BWC Status window. Detail raw
data format to parsing the retrieved raw data of BWC status information would be
introduced at section 12.2.
8.4 BWC remote control
Once the Bluetooth link is established between In-Car Trigger and BWC, In-Car
Trigger could the listed BWC status via defined UART command through UART
interface:
 Operating status:
Includes turn recording on/off remotely.
Test UI provide checkbox in BWC Control window for user to select the
configuration to control BWC’s operating status. It will generate raw data UART
command and dispatch to In-Car Trigger via UART interface to control BWC
remotely. Detail raw data of UART command format to remotely control the BWC
would be introduced at section 12.2
8.4.1
Proximity trigger recording
Proximity trigger recording is an automatic BWC recording remote control
function base on the RSSI, which is related to different distance between the
paired BWC and In-Car Trigger, to turn on/off BWC’s recording remotely:
 If the RSSI is lower than a threshold which is considered that the officer
leave the patrol car (EX. for examining the crime scene), In-Car Trigger
will remotely turn on BWC’s recording automatically.
 If the RSSI is higher than a threshold which is considered that the officer
sit back to the driver seat of patrol car, In-Car Trigger will remotely turn
off BWC’s recording automatically.
In Test UI, In-Car Trigger Status window display the listed configuration of
proximity trigger function:





Proximity Trigger EN: A radio box that indicate the proximity trigger is
enabled or not. It will be set if proximity trigger function is enabled.
InCarDelay: A time delay parameter for considering the BWC is located in
the patrol car. Refer to the following description on InCar Thres
parameter.
InCar Thres: The upper RSSI threshold, BWC would be considered
located in the patrol car if the RSSI is higher than this value for defined
InCarDelay secs.
OutCarDelay: A time delay parameter for considering the BWC is located
in the patrol car. Refer to the following description on OutCar Thres
parameter.
OutCar Thres: The lower RSSI threshold, BWC would be considered
located out of the patrol car if the RSSI is lower than this value for defined
OutCarDelay secs.
All the parameters above for proximity trigger configuration could also be
configured under the In-Car Trigger Control window of Test UI:
8.4.2
Light bar trigger recording
Light bar trigger recording is another automatic BWC recording remote control
function base on the patrol car’s light bar status. A status transition from
turned-off to turned-on of light bar will make In-Car Trigger remotely turn on
the both paired BWCs’ recording.
In Test UI, In-Car Trigger Status window display light bar trigger function is
enabled or not:
Also it could be configured in In-Car Trigger control window:
8.4.3
Remote recording control integration
Through the introduction of section 8.4 to 8.4.2, multiple scenario would make
In-Car Trigger remotely turn on/off the recording if it’s paired BWCs
separately. This section summarize the all these scenario to show how they
work together.

Base on the recording is turned on or off in received status of paired BWC,
the remote recording control scenarios could be listed in the following cases
tagged in the control flow above:
A. Forbidden remotely turn off recording due to local triggering
If BWC currently is recording, which is triggered by click the REC button
of BWC locally, then it is not allowed to turn off the BWC recording
remotely via wireless.
B. Forbidden remotely turn off recording due to light bar triggering
Continue from (A). If BWC currently is recording, which is triggered by
light bar triggering and the light bar is still turned on, then it is not allowed
to turn off the BWC recording remotely via wireless.
C.
Remote turn off recording due to proximity triggering.
Continue from (B). If BWC currently is recording, proximity triggering is
enable and BWC is located in patrol car for defined duration. In-Car
Trigger would remotely turn off the BWC’s recording.
D. Remote turn off recording due to user’s demand.
Continue from (C). User could still dispatch remote command to In-Car
Trigger to turn off the recording of BWC.
E. Turn on recording due to proximity triggering
If BWC currently is not recording, proximity triggering is enabled, and
BWC is located out of patrol car for defined duration. In-Car Trigger will
automatically turn on this BWC’s recording remotely.
F. Turn on recording due to Light bar triggering
Continue from (E). If BWC currently is not recording, proximity triggering
is enabled, and BWC is located out of patrol car for defined duration. InCar Trigger will automatically turn on this BWC’s recording remotely.
G. Turn on recording due to user’s demand
Continue from (F). User could still dispatch remote command to In-Car
Trigger to turn on the recording of BWC.

13 Controller firmware update
In-Car Trigger provide 2 ways to flush/update the firmware of controller: Hardware
flushing and Serial bootloader.
13.1 Hardware flushing
Firmware hardware flushing is the way that completely erase the In-Car Trigger
controller and replace it with a new provided firmware image. The cover case of
In-Car Trigger have to be removed and a controller vendor specific fixture is
required for this flushing process.
13.1.1 Environment setup
Texas Instruments CC Debugger is the fixture need to connect to the In-Car
Trigger to erase the In-Car Trigger controller.
Texas Instruments Smart RF Flash Programmer software package contains
the driver of CC debugger to let the connected host system to identify this
device. Download and install the Smart RF Flash Programmer from Texas
Instruments official Website http://www.ti.com/tool/flash-programmer.
After successfully install the Smart RF Flash Programmer on the host system,
plug the USB connector of CC debugger into the USB port of host system. CC
debugger should be identified under the device manager of the connected
host system.
Connect the 2x5 connector of CC Debugger to the In-Car Trigger PCB as the
pin map below.
Click the reset button of CC Debugger, the connection status LED should turn
to green if the debugger successfully connect to the In-Car Trigger controller.
13.1.2
Firmware Flushing
Once installing the Smart RF Flash Programmer, Launch Smart RF Flash
Programmer on host system to bring up the In-Car Trigger controller flash
programming user interface.
Correctly select the target device and make sure CC debugger is recognized
by the flash programmer
Select the provided firmware image *.hex file for flushing the In-Car Trigger
controller.
Configure Flushing procedure and click “Perform action” to start firmware
flushing.
Unplug the CC Debugger from Inn-Car Trigger when flash programmer
generate programming successfully message.
13.2Serial Bootloader
Serial Bootloader provide a pure software process to flush the firmware of
controller with provided firmware image file. The process requires no specific
fixture or removing the cover case.
[Note]
Serial Bootloader is staring phasing-in In-Car Trigger controller firmware since V1.01
to provide ability to update the controller to the LATER version firmware. If the
current controller firmware version of In-Car Trigger is less than V1.01, it still require
to hardware flushing the firmware to V1.01 with provided firmware image first to
support serial bootloader.
13.2.1 Environment setup
The M12 pigtail of In-Car Trigger have to be connected to a 8~30V power
supply and Windows system host device. Make sure In-Car Trigger is powered
on, the connected Windows system successfully identify the UART interface on
M12 pigtail, and DO NOT let any application (includes the In-Car Trigger Test
UI) on Windows system occupy the UART port.
13.2.2 Firmware flushing
The listed file will be provided for the usage of serial bootloader function.
 InCarTriggerBootloader.exe: An executable of serial bootloader
application.
 InCarTriggerBootloader.bat: Batch script.
 InCarTriggerFW_A****.bin:
In-Car Trigger controller firmware.
Before launching the firmware flushing process, edit the provided
InCarTriggerBootloader.bat script to make sure the filename specified in batch
script is identical to the provided *.bin file.
Save and execute InCarTriggerBootloader.bat script to initiate the firmware
flushing process and pop up command line window below to notify user the
progress of whole process:
 Stage 1: Bootloader application will poll all serial ports of system to search
out the one connected to the In-Car Trigger.
 Stage 2: Bootloader application will generate UART command to switch the
In-Car Trigger to handle firmware flushing commands. If In-Car Trigger
successfully receive this command, it would generate 2 long beeping to
notify ready to receive the controller firmware image.
 Stage 3: Bootloader application will keep displaying how many bytes are
already sent versus how many bytes should be sent as the progress
notification on firmware transmission.

Stage 4: Bootloader application will poll the return status sent from In-Car
Trigger after finish the firmware transmission.
