STM32WB15 BLE not working

[CBuek.1]

Hi, I have shared my project schematic. it's should work or not? (SMPs not used)

Problem : BLE cannot advertise, but this configuration in STM32CubeIDE can work with NUCLEO-WB55.

[CBuek.1 · Accepted solution]

Hello.

Now my custom board is working.

This is my solution step by step and some problem I saw in code generation.

STM32CudeIDE version 1.10.1

STM32WBCube version 1.14.1

#1 : Install wireless stack firmware. (new IC MCU)

For new IC MCU need to flash wireless stack firmware. In my case user stm32wb1x_BLE_Stack_full_fw.bin found in

../../STM32Cube/Repository/STM32Cube_FW_WB_V1.14.1/Projects/STM32WB_Copro_Wireless_Binaries/STM32WB1x/stm32wb1x_BLE_Stack_full_fw.bin

upload this firmware to the MCU by using STM32CubeProgrammer start address 0x08021000

please see instructions in "Release_Notes.html" (important)

#2 ​ : Test with example

This step make sure your board can work.

In my case I test with BLE_HeartRate example.

../../STM32Cube/Repository/STM32Cube_FW_WB_V1.14.1/Projects/NUCLEO-WB15CC/Applications/BLE/BLE_HeartRate

Import to STM32CudeIDE and compile without change anything the start debug or just upload to the board

#3 : Create new project

Please follow project configuration in YouTube STMicroelectronics channel

Simple BLE application generated from CubeMX

for STM32WB15xx please change some configuration because of RAM limitation ref: NUCLEO-STM32WB15 HardFault Error with BLE custom Template.

config : (in example use this config value I don't known how to calculation 😅 )

Minimum Heap Size : 0x400

Minimum Stack Size : 0x1000

# 3.1 Fix code generation (for 1.14.1)

# fix startup script (this bug or developer need to change manually? )

replace all script startup_stm32wb15ccux.s generated with STM32CudeIDE by startup_stm32wb15ccux.s script in BLE_HeartRate example project. (see #2)

# fix app_entry.c

​ In this step the BLE can advertise but not normal working (don't known why). GPIO repeat toggle without init or not using (my LED blink repeatedly). I have fixed by modified in MX_APPE_Init() function code generated with

void MX_APPE_Init(void)
{
  System_Init();       /**< System initialization */
 
  SystemPower_Config(); /**< Configure the system Power Mode */
 
  HW_TS_Init(hw_ts_InitMode_Full, &hrtc); /**< Initialize the TimerServer */
 
/* USER CODE BEGIN APPE_Init_1 */
	APPD_Init();
 
	  /**
	   * The Standby mode should not be entered before the initialization is over
	   * The default state of the Low Power Manager is to allow the Standby Mode so an request is needed here
	   */
	  UTIL_LPM_SetOffMode(1 << CFG_LPM_APP, UTIL_LPM_DISABLE);
 
 
/* USER CODE END APPE_Init_1 */
  appe_Tl_Init();	/* Initialize all transport layers */
 
  /**
   * From now, the application is waiting for the ready event (VS_HCI_C2_Ready)
   * received on the system channel before starting the Stack
   * This system event is received with APPE_SysUserEvtRx()
   */
/* USER CODE BEGIN APPE_Init_2 */
 
/* USER CODE END APPE_Init_2 */
   return;
}

# Compile and Run ➡�? 😁

# Found some bug (or I missed something?)

In code generation I can't start advertising with low power mode by change APP_BLE_FAST_ADV to APP_BLE_LP_ADV in Adv_Request(APP_BLE_LP_ADV); function.

because in this function always with fast mode ?

solution

BleApplicationContext.Device_Connection_Status = NewStatus;
  /* Start Fast or Low Power Advertising */
  ret = aci_gap_set_discoverable(ADV_TYPE,
		  NewStatus == APP_BLE_FAST_ADV ? CFG_FAST_CONN_ADV_INTERVAL_MIN : CFG_LP_CONN_ADV_INTERVAL_MIN,
				  NewStatus == APP_BLE_FAST_ADV ?  CFG_FAST_CONN_ADV_INTERVAL_MAX : CFG_LP_CONN_ADV_INTERVAL_MAX,
                                 CFG_BLE_ADDRESS_TYPE,
                                 ADV_FILTER,
                                 0,
                                 0,
                                 0,
                                 0,
                                 0,
                                 0);

Thanks,
