Description

If I use the tcp listener from https://github.com/brad28b/meshtastic-cli-receive-text/blob/main/read_messages_tcp.py it gets stuck every once in a while, crashing in a background thread apparently. I can't rescue it and once it crashes, no events will be received.

bmidgley@nightvision:~ $ meshtastic --version
2.5.9
bmidgley@nightvision:~ $ python --version
Python 3.11.2
bmidgley@nightvision:~ $ dpkg -l | grep meshtastic
