Main function:
 
the possible protocols are:
1 = UDP
2 = TCP in connect mode (Client)
3 = TCP in listen mode (Server)
4 = FTP
5 = HTTP
6 = SMTP
7 = POP3
8 = MMS
9 = SSL TCP in connect mode (Client)
Two pairs with a different protocol number but the same index identify two distinct sockets.
Example: both 1,7 and 2,7 are valid identifiers simultaneously; the former identifies a UDP socket and the later, a TCPconnected socket.

Number of Sockets
the number of sockets per protocol is limited.
*UDP: 8 sockets
*TCP Clients (with 1 SSL TCP client maximum included): 8 sockets
*TCP Servers: 4 sockets

Notes
the creation of basic sockets (TCP/UDP) is not commercial but other features are locked by a commercial feature named "internet library". The Internet Applicationcommands used for socket/session creation will return a "+CME ERROR: 839"enable the features, you can refer to the Firmware AT Commands Interface Manual (especially the AT+WCFM command) and we recommend you to contact your Sierra Wireless distributor or sales
