Question

BLE not advertising - STM32WB5MMGH

Hi,
I'm working with stm32wb5mmgh to transmit data. The thing is BLE starts to advertise only in the debug mode if I upload it in the device its not showing. So what I did I turned on led when it starts to advertise as I mentioned in the below code.

 

 

 

/* Update Advertising data */
ret = aci_gap_update_adv_data(sizeof(a_AdvData), (uint8_t*) a_AdvData);
if (ret != BLE_STATUS_SUCCESS)
{
APP_DBG_MSG("==>> Start Fast Advertising Failed , result: %d \n\r", ret);
}
else
{
APP_DBG_MSG("==>> Success: Start Fast Advertising \n\r");
HAL_GPIO_WritePin(GPIOA, GPIO_PIN_9, GPIO_PIN_SET);
}

 

 

 

The LED turned on after I uploaded the code but the BLE is not showing.

Used FUS Version : v1.2.0.0, STACK Version : v1.16.0.4, stm32wb5x_BLE_Stack_full_fw.bin.

Also I change the linker Script as mentioned in this wiki link. I also share the linker script.

Hello,

The modification around the linker script describes in the wiki pages need to be done when using extended binaries (stm32wbxx_BLE_Stack_full_extended_fw.bin, stm32wbxx_BLE_HCILayer_extended_fw.bin), in your case it's not needed. You are currently facing to this issue:
