2.2.7. AT+QISEND Send Data
In buffer access mode (<access_mode>=0) or direct push mode (<access_mode>=1), the data can be
sent via AT+QISEND. If the data is sent to the module successfully, SEND OK will be returned. Otherwise
it will return SEND FAIL or ERROR. SEND FAIL indicates the sending buffer is full and the data can be
tried to be resent. ERROR indicates it encounters an error in the process of sending data and the data
should be delayed for some time to be sent. SEND OK does not mean the data has been sent to the
server successfully. Please query whether the data has reached the server by
AT+QISEND=<connectID>,0.
If <service_type>="TCP" or "UDP", it is the port of remote server.
If <service_type>="TCP LISTENER" or "UDP SERVICE", the port is invalid.
If <service_type>="TCP INCOMING", it is the port of remote client.
<local_port> Integer type. Local port number. Range: 0–65535.
