T-Beam `E (141058) task_wdt: Task watchdog got triggered.` After `enqueuing for send` using Meshtastic Firmware

[JCBuck]

I have a set of T-Beam m8n devices with board revision T22_V1.1 20210222 all have been flashed to Meshtastic 2.3.4.ea61808 Beta with the fully erase option

I have one of 4 devices that constantly freezes/crashes right after booting

Comparing the logs side by side to one that isn't crashing or having the watchdog timeout implies that maybe the LoRa radio isn't responding... Is the radio toast? I think this was happening even before this firmware version since i got the device originally but never had time to troubleshoot it.

It seems that something blocks the running of the program, causing the watchdog to reset. Can you try this test firmware to see if each unit is normal? https://github.com/Xinyuan-LilyGO/LilyGo-LoRa-Series/tree/master/firmware/hardware_test/t-beam-v1.x/Comprehensive You need to write the firmware of a fixed model, and then press the IO38 button to switch the function page. After booting, diagnostic information will be output in the Serial

I have 915mhz versions of the tbeam, does it matter if i flash the 868, or 433 firmware?

[lewisxhe]

For the 915 version, you can only use 915 or 868. The transmission of writing 433 will cause problems.

Good to know I will give the 868 a try

Does this mean the Radio does not work? Could I get it replaced?
