@david-cermak The problem seems to be solved, and now I've changed the modem to another model and the problem doesn't appear.

My business is to start a task to query the 4G signal quality, and use Alibaba Cloud IoT for cloud connection. I don't know if it is in data mode (the data is still being received, judged according to on_cmux: state: 2 in the Log), the execution of the AT command caused this exception.

int rssi, ber;
for (;;)

@hqs1 Was your issue fixed by the recent CMUX changes? (I thought it could, as we added a locking mechanism when switching modes)

@david-cermak The problem is still not solved, I try to create a task to read the signal quality constantly. However, this problem occurs when there is network data communication. Not sure if the dce handle is not thread safe

@hqs1 Thanks for sharing the detailed STR! Will try to reproduce the problem on my end.
In the meantime, could you please try to remove this line:
I suspect the defragmenting code in CMUX protocol might cause this corruption.

Oh, sorry. Missed this in the last unique-buffer refactor; should be buffer.size instead of buffer_size (dot, not underscore)

@david-cermak Now after deleting the macro definition, there is no previous problem. Although it is said that because the serial port reads a large amount of data, the watchdog will be triggered, but it does not affect the network data transmission and the signal quality of the AT command to read the 4G modem.

commented on May 30, 2024
Thanks for testing this! This explains the problem and also the reason I wasn't able to reproduce the problem. IIRC your modem sends bigger payloads. The defragmenting logic however expects the max payload on CMUX level to be 127 (one byte length) and I doesn't provide any means to limit the buffer size (unless we set really big buffer sizes).
I think the WDT issue would disappear if you set less verbose logging (Debug/Info), as it seems it waits for printing the raw data to the console (ESP_LOG() or ESP_HEXDUMP())
I'll think about the way of enabling the defragmening dynamically, only on limited payloads...
