Hi, I have a problem with MC60 simple communication with HTTP POST.
When sending the AT HTTPPOST command I receive the CONNECT response but when sending the request data to the server I never receive the final OK that confirms the communication. I’ve tried waiting longer than long enough for a response and get the error code “+CME ERROR: wait http response timeout” .
I wrote procedure based on GSM_HTTP_AT_Commands_Manual_V1.4 examples. Attached execution logs:
