@troy-salt If you have access to the device, you can read the flash with esptool.py.

@paloma You can configure Filezilla in a way, that double-click on a file in the LoPy pane will open that file in your Favorite editor. Storing that file will transfer it back to the LoPy. For REPL, you might also use other tools like screen, picocom, putty, .., which support VT100 code sequences, in case you need them.

@cmisztur Editing pycom-micropython-sigfox/esp32/pycom_version.h you can change the version, but I don't know how to change the name and the other parameters returned by uos.uname(). I'm sorry. Regards,
