Not able to see BLE Advertisement

[PB S.1]

Hi,

I am using STM32WB5MMG MCU with the latest FUS V1.2.0 and BLE_Stack_full V1.13.1.

I have my own custom BLE application. After enabling BLE fast advertisement using the API "Adv_Request(APP_BLE_FAST_ADV);", I cannot able to see the advertisement in ST BLE ToolBox Mobile App.

I am getting "BLE_STATUS_SUCCESS" as a return value.

Here I am attaching the code snippet

void Adv_Request(APP_BLE_ConnStatus_t New_Status)
{
  tBleStatus ret = BLE_STATUS_INVALID_PARAMS;
  uint16_t Min_Inter, Max_Inter;
 
  if (New_Status == APP_BLE_FAST_ADV)
  {
    Min_Inter = AdvIntervalMin;
    Max_Inter = AdvIntervalMax;
  }
  else
  {
    Min_Inter = CFG_LP_CONN_ADV_INTERVAL_MIN;
    Max_Inter = CFG_LP_CONN_ADV_INTERVAL_MAX;
  }
 
  // Stop the timer, it will be restarted for a new shot */
  /* Commented out to prevent the adv from ever stopping LP 04_24_2020 */
  //HW_TS_Stop(BleApplicationContext.Advertising_mgr_timer_Id);
 
 
  #if(CFG_DEBUG_APP_TRACE != 0)
    APP_DBG_MSG("First index in %d state \n",
    BleApplicationContext.Device_Connection_Status);
  #endif
  
  if ((New_Status == APP_BLE_LP_ADV)
        && ((BleApplicationContext.Device_Connection_Status == APP_BLE_FAST_ADV)
            || (BleApplicationContext.Device_Connection_Status == APP_BLE_LP_ADV)))
  {
      /* stop any current advertising */
      ret = aci_gap_set_non_discoverable();
      if (ret == BLE_STATUS_SUCCESS)
      {
        DmConsolePrintf("BLE: Successfully Stopped Advertising \r");
        #if(CFG_DEBUG_APP_TRACE != 0)
          APP_DBG_MSG("Successfully Stopped Advertising\n");
        #endif
      }
      else
      {
        DmConsolePrintf("BLE: Stop Advertising Failed | result: %d \n\r", ret);
        #if(CFG_DEBUG_APP_TRACE != 0)
          APP_DBG_MSG("Stop Advertising Failed , result: %d \n", ret);
        #endif
      }
  }
 
  BleApplicationContext.Device_Connection_Status = New_Status;
  /* Start Fast or Low Power Advertising */
    
  /* start the advertising */
  /* modified to not sent the local name and send the adv uuid */
  /* adv type changed to ADV_SCAN_IND to respond to scans LP 11-21-2019 */
  ret = aci_gap_set_discoverable(
        ADV_IND,
        Min_Inter,
        Max_Inter,
        PUBLIC_ADDR,
        NO_WHITE_LIST_USE, 
        0,
        NULL,
        sizeof(advertisement_uuid),
        advertisement_uuid,
        0,
        0);
    
  /* Update the advertising data with the manf specific data */
  ret = aci_gap_update_adv_data(sizeof(manuf_data), (uint8_t*) manuf_data);
 
  if (ret == BLE_STATUS_SUCCESS)
  {
      if (New_Status == APP_BLE_FAST_ADV)
      {
         DmConsolePrintf("BLE: Successfully Start Fast Advertising \n\r");
         APP_DBG_MSG("Successfully Start Fast Advertising\n" );
         
         /* Start Timer to get the timeout for advertising stop */
         /* Commented out to prevent the adv from ever stopping LP 04_24_2020 */
         // HW_TS_Start(BleApplicationContext.Advertising_mgr_timer_Id, INITIAL_ADV_TIMEOUT);
      }
      else
      {
        DmConsolePrintf("BLE: Successfully Start Low Power Advertising \n\r");
        #if(CFG_DEBUG_APP_TRACE != 0)
          APP_DBG_MSG("Successfully Start Low Power Advertising\n");
        #endif
      }
  }

"I cannot able to see the advertisement in ST BLE ToolBox Mobile App"

Can you see it in any other BLE scanner apps?

[PB S.1]

Hi Andrew,

Even with the other scanner apps also I cannot able to see it.

[Javier1]

Did you tried lightblue ble?

[PB S.1]

Hi Javier,

Even I tried lightblue ble app, but not able to see advertisement

Hello,

When you say "I am getting "BLE_STATUS_SUCCESS" as a return value." , you have check the return value of aci_gap_set_discoverable command ?

Best Regards

Hi,

I checked the return value of both "aci_gap_set_discoverable" and "aci_gap_update_adv_data". Both of them are giving "BLE_STATUS_SUCCESS" as a return value.

Hello,

If you take an application available in STM32CubeWB package, are you able to see advertising data ? For example, you can try with BLE_p2pServer example.

Best Regards
