LoPy4 REPL in Atom not working with firmware higher than 1.20.1

[jake_hh]

Hello,

I just started on using my LoPy4 with Atom (Windows 10 64bit) on top of a Pytrack. First I updated the firmware on the Pytrack as well as on the LoPy4 to the latest version (1.20.2.rc6). I then couldn't connect to the LoPy4 with the REPL in Atom. After trying a lot of thing I found out, that the REPL console only works if I downgrade the firmware on the LoPy4 to version 1.20.1.
Any of the newer firmwares (1.20.1.r1, 1.20.1.r2,.... ) doesn't work and I can't use the REPL an/or program the LoPy4.

Is there something I am missing? Does anyone know what to do?

Thanks and regards,
Jan

I have just reported exact same problem with VSCode and PySense board.

Thanks for this, even if no one ever responded. I had my REPL working on one LoPy4 with 1.20.2.rc6 but not with another (same firmware version). I downgraded to 1.20.1 and it worked.
