BLE connection problem with STM32WB5MMG
LoWnT13 opened this issue · 6 comments
Hi,
I just bought a ST32WB5MMG module from ST and I tried to use a simple BLE code but I can't get a BLE connection with any device.
I already tried to flash and start "stm32wb5x_BLE_HCILayer_fw.bin" at address "0x080E0000" following the Release Notes for STM32WB Copro Wireless Binaries but it didn't help.
I ask for help to know if there is a special procedure to activate it.
Thank you for your help.

Hi @LoWnT13
when you told ST32WB5MMG module could you be more precise? which target you select in the Arudino IDE menu?
I use: Generic STM32WB series --> Generic WB5MMGHx
OK. So example used specific board definition:
So you have to add the generic one and probably have to configure SystemClock_Config to use HSE.
I've tested the Generic variant with my STM32WBMM-DK.
I've made these change to the ButtonLed.ino examples:
1- Redefine the clock config:
#include "lock_resource.h"
extern "C" void SystemClock_Config(void) {
RCC_OscInitTypeDef RCC_OscInitStruct = {};
RCC_ClkInitTypeDef RCC_ClkInitStruct = {};
RCC_PeriphCLKInitTypeDef PeriphClkInitStruct = {};
/* This prevents concurrent access to RCC registers by CPU2 (M0+) */
hsem_lock(CFG_HW_RCC_SEMID, HSEM_LOCK_DEFAULT_RETRY);
/** Configure LSE Drive Capability
*/
HAL_PWR_EnableBkUpAccess();
__HAL_RCC_LSEDRIVE_CONFIG(RCC_LSEDRIVE_LOW);
/** Configure the main internal regulator output voltage
*/
__HAL_PWR_VOLTAGESCALING_CONFIG(PWR_REGULATOR_VOLTAGE_SCALE1);
/* This prevents the CPU2 (M0+) to disable the HSI48 oscillator */
hsem_lock(CFG_HW_CLK48_CONFIG_SEMID, HSEM_LOCK_DEFAULT_RETRY);
/** Initializes the RCC Oscillators according to the specified parameters
* in the RCC_OscInitTypeDef structure.
*/
RCC_OscInitStruct.OscillatorType = RCC_OSCILLATORTYPE_HSI48 | RCC_OSCILLATORTYPE_HSI
| RCC_OSCILLATORTYPE_HSE | RCC_OSCILLATORTYPE_LSE;
RCC_OscInitStruct.HSEState = RCC_HSE_ON;
RCC_OscInitStruct.LSEState = RCC_LSE_ON;
RCC_OscInitStruct.HSIState = RCC_HSI_ON;
RCC_OscInitStruct.HSI48State = RCC_HSI48_ON;
RCC_OscInitStruct.HSICalibrationValue = RCC_HSICALIBRATION_DEFAULT;
RCC_OscInitStruct.PLL.PLLState = RCC_PLL_ON;
RCC_OscInitStruct.PLL.PLLSource = RCC_PLLSOURCE_HSE;
RCC_OscInitStruct.PLL.PLLM = RCC_PLLM_DIV2;
RCC_OscInitStruct.PLL.PLLN = 8;
RCC_OscInitStruct.PLL.PLLP = RCC_PLLP_DIV2;
RCC_OscInitStruct.PLL.PLLR = RCC_PLLR_DIV2;
RCC_OscInitStruct.PLL.PLLQ = RCC_PLLQ_DIV2;
if (HAL_RCC_OscConfig(&RCC_OscInitStruct) != HAL_OK) {
Error_Handler();
}
/** Configure the SYSCLKSource, HCLK, PCLK1 and PCLK2 clocks dividers
*/
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;
if (HAL_RCC_ClockConfig(&RCC_ClkInitStruct, FLASH_LATENCY_3) != HAL_OK) {
Error_Handler();
}
/** Initializes the peripherals clocks
*/
/* RNG needs to be configured like in M0 core, i.e. with HSI48 */
PeriphClkInitStruct.PeriphClockSelection = RCC_PERIPHCLK_SMPS | RCC_PERIPHCLK_RFWAKEUP
| RCC_PERIPHCLK_CLK48SEL | RCC_PERIPHCLK_USB
| RCC_PERIPHCLK_RNG;
PeriphClkInitStruct.UsbClockSelection = RCC_USBCLKSOURCE_HSI48;
PeriphClkInitStruct.RngClockSelection = RCC_RNGCLKSOURCE_HSI48;
PeriphClkInitStruct.RFWakeUpClockSelection = RCC_RFWKPCLKSOURCE_LSE;
PeriphClkInitStruct.SmpsClockSelection = RCC_SMPSCLKSOURCE_HSE;
PeriphClkInitStruct.SmpsDivSelection = RCC_SMPSCLKDIV_RANGE0;
if (HAL_RCCEx_PeriphCLKConfig(&PeriphClkInitStruct) != HAL_OK) {
Error_Handler();
}
LL_PWR_SMPS_SetStartupCurrent(LL_PWR_SMPS_STARTUP_CURRENT_80MA);
LL_PWR_SMPS_SetOutputVoltageLevel(LL_PWR_SMPS_OUTPUT_VOLTAGE_1V40);
LL_PWR_SMPS_Enable();
/* Select HSI as system clock source after Wake Up from Stop mode */
LL_RCC_SetClkAfterWakeFromStop(LL_RCC_STOP_WAKEUPCLOCK_HSI);
hsem_unlock(CFG_HW_RCC_SEMID);
}
2- Then change the LED_BUILTIN and USER_BTN to use as the generic define them as PNUM_NOT_DEFINED
const int ledPin = PA2;
const int buttonPin = PC12; // set buttonPin to on-board user button
3- Change default Serial pins as generic define on by default but probably does not match to your board:
Serial.setRx(PB7);
Serial.setTx(PB6);
Serial.begin(115200);
4- Add board definition to define the HCISharedMemTransportClass HCISharedMemTransport;
#elif defined(ARDUINO_NUCLEO_WB15CC) || defined(ARDUINO_P_NUCLEO_WB55RG) || defined(ARDUINO_STM32WB5MM_DK) || defined(P_NUCLEO_WB55_USB_DONGLE) || defined(ARDUINO_GENERIC_WB5MMGHX)
Then it works as expected.
So you have to properly update the example to fit your board.
Hi, the module doesn't work with the stack 1.16.0.4 but it works fine with the 1.15.
@fpistm , do you test it with the latest version of the stack ?
BTW thank you for the HSE config.

Hi @jmchiappa
I've checked and the fw was an old one. I've updated and it does not work.
After some investigation, the fw was not properly updated. Updating it a second time and it works.
Think to press start wireless stack too in the Cube Programmer.
