WeAct Studio STM32WB55 doesn't work with this BLE stack

[tankist-git-2]

I have WeAct Studio STM32WB55 board STM32WB55 board. I use Arduino IDE 2.3.6. I use "STM32 MCU based boards by STM" 2.11.0 platform. I use "STM32duinoBLE" 1.4.1 library. I uploaded suggested firmware stack for radio module MCU for this chip (stm32wb5x_BLE_HCILayer_fw.bin 1.24.0). I tried to use "Peripheral -> Advertising -> RawDataAdvertising" example.

The result is my code is hanging in the infinite loop inside BLE.begin() function.

The further investigation showed that the code is hanging in HCISharedMemTransportClass::write() function in the line:
while (!phase_reset);
during the HCI.reset() stage. The phase_reset flag set just in one place: in function evt_received() which is never called.

I added some log in code so there is a result:

Starting application...
syscmd_status_not, status:1
WB copro FW version = 1.24.0
syscmd_status_not, status:0
syscmd_status_not, status:1
IPM Channel Open Completed
Command tx -> 0x1 0x3 0xC 0x0
Invoking mbox_write()...
mbox_write() done

I expected phase_reset done message which never happened because of infinite loop in while (!phase_reset);

I attached my sketch directory and library directory to reproduce the error. The only differences are adding log messages (I prepended them with /TEMP+/ prefix). Also I attached Arduino settings for my board.

BLE works on any listed boards. No description. Close this issue.

Are you serious? I didn't even have time to write a description, and you already closed it?

When you create an issue you fill it before submit it. You don't add a new comment after open it.

Unfortunately, it will be hard to help without harwae anyway, as you used the generic you have to override the SystemClock_Config as by default it configure the HSI .
So you have to define a new one (as it is a weak function) to configure and use the HSE.
See example here:
https://github.com/stm32duino/Arduino_Core_STM32/blob/339e63528345bbdc45f854ca84753172faa108b8/variants/STM32WBxx/WB35C(C-E)UxA_WB55C(C-E-G)U/variant_P_NUCLEO_WB55_USB_DONGLE.cpp#L73C11-L73C29

I would say you can even try the one pointed before:

I tried your config but it was unsuccessful. The output is still shows hanging in the same place (even less than before):

Starting application...
syscmd_status_not, status:1
WB copro FW version = 1.24.0
syscmd_status_not, status:0
syscmd_status_not, status:1
IPM Channel Open Completed
Command tx ->

Could you give me another piece of advice what to check?

Also one more thing, USB doesn't recognized by PC normally with stock clock config and with your clock config. I tried myself the following clock config and that allows USB to work normally:

extern "C" void SystemClock_Config(void) {
	RCC_OscInitTypeDef RCC_OscInitStruct = {0};
	RCC_ClkInitTypeDef RCC_ClkInitStruct = {0};
	RCC_PeriphCLKInitTypeDef PeriphClkInitStruct = {0};

	RCC_OscInitStruct.OscillatorType = RCC_OSCILLATORTYPE_HSE | RCC_OSCILLATORTYPE_HSI48;
	RCC_OscInitStruct.HSEState = RCC_HSE_ON;
	RCC_OscInitStruct.HSI48State = RCC_HSI48_OFF;
	RCC_OscInitStruct.PLL.PLLState = RCC_PLL_ON;
	RCC_OscInitStruct.PLL.PLLSource = RCC_PLLSOURCE_HSE;
	RCC_OscInitStruct.PLL.PLLM = RCC_PLLM_DIV2; // 32 / 2 = 16 MHz (PLL input clock)
	RCC_OscInitStruct.PLL.PLLN = 12;             // 16 * 12 = 192 MHz (PLL working clock)
	RCC_OscInitStruct.PLL.PLLP = RCC_PLLP_DIV3;
	RCC_OscInitStruct.PLL.PLLR = RCC_PLLR_DIV3; // 192 / 3 = 64 MHz (SYSCLK)
	RCC_OscInitStruct.PLL.PLLQ = RCC_PLLQ_DIV4; // 192 / 4 = 48 MHz (USB)
	HAL_RCC_OscConfig(&RCC_OscInitStruct);

	PeriphClkInitStruct.PeriphClockSelection = RCC_PERIPHCLK_USB;
	PeriphClkInitStruct.UsbClockSelection = RCC_USBCLKSOURCE_PLL;
	HAL_RCCEx_PeriphCLKConfig(&PeriphClkInitStruct);

	RCC_ClkInitStruct.ClockType = RCC_CLOCKTYPE_HCLK4|RCC_CLOCKTYPE_HCLK2|RCC_CLOCKTYPE_HCLK|RCC_CLOCKTYPE_SYSCLK|RCC_CLOCKTYPE_PCLK1|RCC_CLOCKTYPE_PCLK2;
	RCC_ClkInitStruct.SYSCLKSource = RCC_SYSCLKSOURCE_PLLCLK;
	RCC_ClkInitStruct.AHBCLKDivider = RCC_SYSCLK_DIV1;
	RCC_ClkInitStruct.APB1CLKDivider = RCC_HCLK_DIV1;
	RCC_ClkInitStruct.APB2CLKDivider = RCC_HCLK_DIV1;
	RCC_ClkInitStruct.AHBCLK2Divider = RCC_SYSCLK_DIV2;
	RCC_ClkInitStruct.AHBCLK4Divider = RCC_SYSCLK_DIV1;
	HAL_RCC_ClockConfig(&RCC_ClkInitStruct, FLASH_LATENCY_3);
}

Sure this config doesn't compatible with wireless because I've never work with such type of MCU before. But it shows there are a lot of issues with clock config with this MCU.
