ESP32C3 crashing and printing random logs on serial

[Mustafa_ME]

Hi, we have a device based on esp32c3, it is reading from adc with a 40ms interval and based on that reading it is controlling a relay connected to a gpio, which can also be controlled through ble mesh. The device is running bluedroid. All the devices in testing are working fine. Recently we got a complaint from a customer that the device goes completely unresponsive all of a sudden. The logs from the returned device are attached. It is printing random logs, it looks like that it is restarting repeatedly, but no coredump/backtrace or reason is printed. IDF-version is 5.0.5. Any clue what might be happening here? Thanks.

Hard to say, but the glitched characters in the output make me think it may be a power supply issue.

Hard to say, but the glitched characters in the output make me think it may be a power supply issue.

Maybe, we have checked the supply line, it is clean and stable even when the device is malfunctioning. Moreover, device recovers after a power cycle and then randomly goes into this state again after a few days. No way to replicate the issue as the reason is unknown.

[MicroController]

Is the issue in any way correlated to the switching of the relay?

[Mustafa_ME]

Is the issue in any way correlated to the switching of the relay?

I don't think so, we have many devices in testing that are switching relays periodically and working just fine.
