Change the BLE advertisment value on stm32wb5mm

Fust3 · ‎2025-03-27

Hello I'm very new in stm32wbX programming and I've created a ble service with custom advertise data packet 0xff with values 0x60,0x61 in app_ble.c

uint8_t a_AdvData[12] =

{

7, AD_TYPE_COMPLETE_LOCAL_NAME, 'B', 'E', 'A', 'C', 'O', 'N', /* Complete name */

3, AD_TYPE_MANUFACTURER_SPECIFIC_DATA,0x60,0x61,

};

Now what i want it's change the values of data packets, so i've tried to call a function from custom_app.c but seems to crash and i can't see any beacon.

What do you suggest to change the values?

Thanks!

void CustomPrint(){

printf("Called\n");

tBleStatus status;

uint8_t adv_data[12] =

{

7, AD_TYPE_COMPLETE_LOCAL_NAME, 'C', 'H', 'A', 'N', 'G', 'E', /* Complete name */

3, AD_TYPE_MANUFACTURER_SPECIFIC_DATA,0x70,0x71,

};

status =aci_gap_update_adv_data(adv_data, (uint8_t*) adv_data);

printf("End \n");

}

Hello,

I'm attaching project where you can change the advertising data by pressing SW1 on Nucleo STM32WB55 board.

I have created a task for sequencer Adv_Update which is called when pressing SW1.

Please let me know if it works on your side, thank you.

Best regards,

ST support

Hello, Thank you very much but actually I'm using the stm32wb5mm-dk shuld be work in the same way?

I've tried to make these changes on my project, but nothing to do
