Dear Quectel Support Team,
We are experiencing an issue while trying to update the firmware of our FC41D module using the AT+QWLANOTA command. The command returns an ERROR response.
When reviewing the logs, we noticed the following error message: “Could not found response_code:406”.
Could you please check if this issue is related to the Content-Type, Content-Length, or MIME type settings on our HTTP server?
Below are our current module version, the command executed, and the complete log output:
