STM32 MCUs Wireless

Can the STM32WB55 OTA handle encrypted user applications?

As far as I understand, the OTA example provided (BLE_Ota) supports either flashing the user application directly or handing the processing over to CPU2 for decryption of the Wireless firmware (which comes as an encrypted and signed package).Is it po...

I2C error handling.

I am using the following code:  while(HAL_I2C_Master_Transmit(&hi2c1, DEVICE_ADDR, i2cbuffer, 1, 1000) != HAL_OK)  {   /* Error_Handler() function is called when Timeout error occurs.     When Acknowledge failure occurs (Slave doesn't acknowledge its...

I2C Error Trapping

I am using the STM32WB in master mode, polling a single LSM303AGR accelerometer. Using the HAL transmit routine as follows:if(hi2c1.State == HAL_I2C_STATE_READY) {  /* Now send the device address and register to be read with 1 sec delay max*/  while(...

Lora End_Node example doesn't send the right data

I have recently downloaded STM32CubeExpansion_LRWAN_V1.2.1.In the main.c of the End_Node example I commented all the sensor related variables etc. and just tried to send letter 'H' with AppData.Buff[i++] = 'H';The message gets though but it keeps cha...

stm32wb55 : unhandled hardfault in enter to stop mode on LL_HSEM_1StepLock with CFG_HW_RCC_SEMID

I use custom application with FreeRTOS.When I embed a power save mechanism, the FW periodically have an unhandled hardfault when use "maybe" stop mode API.After more investigation like:pending ISR CFG_HW_ENTRY_STOP_MODE_SEMID and CFG_HW_RCC_SEMIDhard...
