I’m working with an STM32WLE5 microcontroller, using code generated by STM CubeMX. My project incorporates LoRaWAN modules, follows the EndNode skeleton, and utilizes FreeRTOS (CMSIS V2.0). The common tasks—such as sensor readings and data transmission—work correctly. However, I encounter problems when writing to flash memory. After sending a LoRa frame with information and saving it to flash, subsequent frame transmission and reception stop functioning.
