I found out about the debugging function pycom.nvs_set('pybytes_debug', debugLevel). How does it work? So far I was able to read the debugging info on the Pymakr console, but I was wondering if it was possible to save this information in a file and to access to this information later on.
Thank you very much.
Adjusting the pybytes debug level in nvs affects when debug statements get printed. If you want to save all information in a file on the device, I would suggest adding the statement in the pybytes debug print function: https://github.com/pycom/pycom-micropython-sigfox/blob/Dev/esp32/frozen/Pybytes/_pybytes_debug.py#L22
Else, I would log the prints over USB to a computer and a minicom, saving the output to a file there. This has the advantage of also saving the coredumps, which would not get saved on the device itself
