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...

STM32 with ANT+ product ?

Dear Members,Is there any STM32 product spesifically for ANT+ ?Examples ? Dev board ?Thanks

1: how do i get my gateway to be connected 2: do i need to use at commands on the I-Nucleo to communicate through it 3: how do i know if the I-Nucleo is sending it data? 4: how do i know if the gateway is receiving any data?

Hi All,I am quite new to LoRa so if I am in the wrong forum area I do apologise. If anyone has any information based on my issues below I would appreciate a reply.I have followed the setup guide from STMicroelectronics for the P-Nucleo-LRWAN2:I have ...
