@fpistm any ideas?
No. I will check when I will have some time.
Hi @miroslavpetrov I've reproduced and try to debug deeply but hard with this series as debug with low power mode is a nightmare (several issue document in the errata sheet). In the case of STM32WL, the deepsleep rely on STOP 2 mode and so it requires to properly init the Serial after the deepsleep.
Describe the bug Using the unmodified example AlarmTimedWakeup.ino from the library and Seeed Lora-E5 Mini board, after the first wake up from deepsleep there is no output on the serial console.
To Reproduce Upload AlarmTimedWakeup example to the board.
Expected behavior I expect the serial port to continue working after wake up
