More Information.
We are using ESPModem driver and Modem SIMCOM A7672
The modem is Connected via USB.
The connection is stable until we request OTA update using https server.
After file transfer is started cfc_acm starts sending "Incorrect number of bytes transferred" and continue doing it during whole download process.
The problem doesn't appear every time but it is pretty often.
