I don't know a thing about Fedors, but if your TT4BT and PC can connect, but there is no evidence of communication, I would verify that you have the Baud rates set correctly, i.e, both set to 19200, N,8, 1 and using KISS.

Recently started using the TT4BT instead of 232-USB cable with my laptop.? Pairs and connects to my phone with APRSDroid.? Running Fedora 31, it pairs but starts the connect process, then errors.? Has anyone else run into this issue and what was your solution?
