Critical fault #11

[mraugit]

T-Beam 1.1 displays "Critical fault #11"

To Reproduce
Steps to reproduce the behavior:
I have 3 T-Beam and one ESP32-Paxcounter devices. The Paxcounter is connected to a PC Python application which sends text messages through the Python API to the 3 T-Beam devices. The T-Beam devices report position and status to the Paxcounter device which gives the data through the Python api to the PC application.

The 3 T-Beam's are powered by battery

Expected behavior
The device firmware should run stable for long time

Device info:

• Device model: TBEAM 1.1
• Software Version 1.2.44

That error code represents an SPI communication failure to the radio and is most likely a hardware issue, since this report is isolated. I'm closing the issue for now. If this occurs again on the latest device firmware (1.2.50 at this time), please open a new github issue and tag me in it. Thanks
