# --- PDP Context ---

// attach/dettach (1/0) from PS (do it before activate PDP context)
AT+CGATT=x
*x = 1/0

// set PDP context
AT+CGDCONT=<cid>[,<PDP_type>[,<APN>[,<PDP_addr>[,<data_comp>[,<head_comp>]]]]]
ex: AT+CGDCONT=<cid>,IP,"m2m.vodafone.pt"

// activate or deactivate PDP context

// show PDP address

# --- GPRS ---

AT+CFUN=1                                     // switch on radio

// set apn
AT+QICSGP=<contextID>[,<context_type>,<APN>[,<username>,<password>[,<authentication>]]]

// activate context

// check IP

# --- SOCKET ---

// open socket
AT+QIOPEN=<contextID>,<connectID>,<service_type>,<IP_address>/<domain_name>,<remote_port>[,<local_port>[,<access_mode>]]

// close socket
AT+QICLOSE=<connectID>[,<timeout>]

// socket state
AT+QISTATE=<query_type>,<contextID>

<socket_state> Integer type. The socket service status.
0 "Initial": connection has not been established
1 "Opening": client is connecting or server is trying to listen
2 "Connected": client/incoming connection has been established
3 "Listening": server is listening
4 "Closing": connection is closing

// send data
AT+QISEND=<connectID>,<send_length>

  Ex:
  AT+QISEND=0,5 //Send fixed-length data and the data length is 5 bytes.
  >test2
  SEND OK

// check if the data has reach destination
AT+QISEND=<connectID>,<send_length>

// disable echo of QISEND
AT+QISDE=0

// read data
AT+QIRD=<connectID>[,<read_length>]
+QIRD: <read_actual_length><CR><LF><data>
// get data from socket

UNSOLICITED COMMANDS
“+QIURC:"recv",<connectID> // available data
+QIURC: "closed",<connectID> // socket closed
+QIURC: "pdpdeact",<contextID> // context shutdown
