Hi Team,
I am using the below environment:
- WICED STUDIO 6.4
- CYBT-483039-EVAL board.
- WMBT tool for sending HCI command.
- demo.hello_client-CYBT_483039_EVAL download UART=COM13 BT_DEVICE_ADDRESS=FFFFFFFFFFFF (sample app for testing)
C:\Users\Admin\Documents\WICED-Studio-6.4\wiced_tools\wmbt\Release>wmbt reset COM13
TRANSPORT_MODE: 0 (HCI)
Opened COM13 at speed: 115200
Close Serial Bus
Opened COM13 at speed: 4000000
Sending HCI Command:
0000 < 01 03 0C 00 >
Received HCI Event:
0000 < 04 0E 04 01 03 0C 00 >
Success
Close Serial Bus
But could not able to write/read BDADDR using below commands:
C:\Users\Admin\Documents\WICED-Studio-6.4\wiced_tools\wmbt\Release>wmbt factory_commit_bd_addr COM13 112233445566
TRANSPORT_MODE: 0 (HCI)
Opened COM13 at speed: 4000000
Close Serial Bus
Opened COM13 at speed: 4000000
Sending HCI Command:
0000 < 01 10 FC 07 66 55 44 33 22 11 00 >
C:\Users\Admin\Documents\WICED-Studio-6.4\wiced_tools\wmbt\Release>wmbt read_bd_addr COM13
TRANSPORT_MODE: 0 (HCI)
Opened COM13 at speed: 4000000
Close Serial Bus
Opened COM13 at speed: 4000000
Sending HCI Command:
0000 < 01 09 10 00 >NOTE: My target is to write the Factory Commit BD ADDR to 20719-B1_bluetooth module from the microcontroller.
(required after programming BT module from micro)
Could you please have a look into it and see if I am missing anything?
Thanks,

Hi RaKa_4741636 ,
I am not sure about your complete HW setup and application flow.
Are you using 20719 module in controller only mode or embedded mode?
I am asking because you have mentioned you are using WICED and then Micro controller to program the module.
So can you please confirm if below is the work flow which you are using:
- make an embedded application using WICED SDK and create a hex image
- download the image to 20719 module via HCI from a micro controller
If then, your next requirement is to set a BD address in flash for each modules , then yes you can read and write the required BD address even in the embedded application itself. Say first you can save it to the nvram (wiced_hal_write_nvram) and then load it (wiced_hal_read_nvram) and set using set BD address API (wiced_bt_set_local_bdaddr). For example , refer How to generate BD address randomly and save in flash for CYW20xx devices?
Let me know if you need any clarification.
Regards,
Anjana

Hi RaKa_4741636 ,
Unfortunately Factory Commit BD address VSC is not supported on 20719 chip.
You may have to use the other options discussed in your previous thread here: Re: Configuring unique BD address for client device in CYBT-483039-EVAL
If you are specifically using controller only mode , then you can use Write_BD_ADDR command.
But please note that this will only work for the duration of power on. Once you power cycle the device , the BD address will go back to default.
24:23.753 com1 c> Write_BD_ADDR BD_ADDR: 112233445566
HCI Command
com1@115200
[01 FC 06]: 66 55 44 33 22 11
opcode = 0xFC01 (64513, "Write_BD_ADDR")
BD_ADDR = "112233445566"
24:23.755 com1 <c Write_BD_ADDR
HCI Command Complete Event
com1@115200
[0E 04]: 01 01 FC 00
event = 0xE (14, "Command Complete")
Num_HCI_Command_Packets = 0x1 (1)
Command_Opcode = 0xFC01 (64513, "Write_BD_ADDR")
Status = 0x0 (0, "Success")

Anjana

I think it is better to do the change like "Store the BDADDR in NVRAM of BT module and load it on every boot of the module".
So before programming the BT module, save the BDADDR in micro first and after programming BT module from micro, store the BDADDR back to the module again.
I think with the help of micro, we can manage read and write BDADDR to BT module respectively. Please confirm?
