How to use FreeRTOS and STM_WPAN on STM32WB5

CKnez.1 · ‎2021-06-02

Hi,

I am using a STM32WB5MMG module and want to use FreeRTOS in combination with BLE.

For ease of programming I am using CubeMX to set everything up.

My goal is to have BLE up and running to be able to connect it to a Client. FreeRTOS is being used to communicate with a LTE Modem and several sensors.

Currently I am stuck on getting the device to boot up properly.

Without the stm_wpan part enabled in CubeMX my code is working fine, but as soon as I enable it, the code gets stuck after power up.

I am basically using the BLE_HeartRateFreeRTOS example but added my code to the default task

Really appreciate any help !!

Thanks in advance
