[Bug]: Unexpected Crashes in Techo Firmware Versions 2.3.12 and 2.3.13 about firmware HOT 9 CLOSED

Currently, I have only been updating without erasing user settings.

Usually this seems okay, but if I get a strange error, erasing is the first thing I try. Quite often it fixes it! Hopefully it helps here too. Do try updating your bootloader too if you haven't before.

Also, should probably ask for as much info as possible now! Is there anything special about the way you're using your device? Are you down-linking MQTT?

The bootloader has been updated, and there have been no crashes for about a week now, so I'm closing this issue. Additionally, I recommend notifying users to update their bootloaders if there are any modifications to it.

I don't think it's been updated since February, but it does seem to be related to these weird issues, at least sometimes. Glad to hear it's looking stable, for now at least!

How frequently are you seeing this? I might have seen something similar once, with several days of uptime, but I've seen this happen prior to 2.3.12 also.

If you haven't tried it already, I'd definitely suggest flashing the erase .uf2 file and making sure you've got the Meshtastic bootloader. If you've never flashed this bootloader, it's worth trying, even if the version is reported as the same, as it seems to be a slightly different build than the one the devices ship with.

Versions 2.3.12 and 2.3.13 will occur approximately within 24 hours.

Additionally, you mentioned erasing the entire system before updating to version 2.3.12? Currently, I have only been updating without erasing user settings.

If this was how you resolved the issue before, I will give it a try. Thank you.

I will first try updating the bootloader. Now I am updating to version 2.3.13 and will observe for a few days.

Additionally, I have two channels with both MQTT up/down enabled. Will this have any effect? The T-ECHO is not necessarily always with the phone. Could this be caused by MQTT?

from firmware.

I don't think there is a known bug with MQTT or anything, but I did see #4179 appear yesterday, so it made me wonder!

My T-Echo didn't respond after installing 2.3.13, only the red light flashed. Tried 2.3.12 and it worked. Tried 2.3.13 again and got the same issue again. In the logs I find:

INFO | ??:??:?? 8 Set radio: final power level=22
INFO | ??:??:?? 28 SX126x init result -2
WARN | ??:??:?? 28 Failed to find SX1262 radio

@micheljung Now that is interesting. The RadioLib version did change with 2.3.12, but I'm not seeing anything like this going on with my T-Echo, so I'm not sure what to make of it. Hopefully one of the radio experts drops by.

Have you also had a go with this?
