the Easy_GPRS_User_guide well explains how suspending (+++) and closing a TCP socket connection (AT+SH). But I wasn’t able to find what happens when the remote host closes a connection.
If the GE865 module isn’t in command mode (it’s exchanging data with the remote host), any module string indicating that the actual connection was closed by the remote host could be confused with the incoming data…
You’ll get NO CARRIER, or you can monitor DCD.
