Resolved! STM32WLE5 write locked not in read after passing RDP from Level 1 to Level 0

Hello,I use STM32WLE5 on a seed studio module LORA-E5 mini where boot0 is not accessible (completely crazy ...). The module comes with a read protection and they ask us to remove RDP (level 1 to level 0) to be able to flash it with a custom program. ...

Resolved! Accidental MCU/Flash write lock up: My misuse or CubeProg bug?

While programming OptionBytes or FW on STM32WLx5 most of the time is OK.In CubeProg I have noticed, that on some MCUs, when I get reading of RDP 0xFF or 0, the next action to program something write related, it could not be done and it's failed.Stati...

Resolved! LoRa packet with CRC error treated as valid

A packet with CRC error has both SUBGHZ_IT_RX_CPLT and SUBGHZ_IT_CRC_ERROR flag set.In stm32wlxx_hal_subghz.c, this leads to both RxCpltCallback() and CRCErrorCallback() being called.https://github.com/STMicroelectronics/STM32CubeWL/blob/main/Drivers...
