2.3.7. AT+QISEND Send Data
In buffer access mode (<access_mode>=0) or direct push mode (<access_mode>=1), the data can be
sent with AT+QISEND. If the data is sent to the module successfully, SEND OK is returned. Otherwise
SEND FAIL or ERROR is returned.
 SEND FAIL indicates the sending buffer is full. In this case, data can be resent.
 ERROR indicates there is an error in the process of sending data. In this case, wait for some time
before you resend the data.
 SEND OK does not mean the data has been sent to the peer successfully. You can query whether
the data has reached the peer with AT+QISEND=<connectID>,0.
