Service Creation +WIPCREATE Continued

Examples:

Command Responses

AT+WIPCREATE=1,1,80

Note: Create the UDP socket on local port 80

with communication index = 1 Ù Wireless

CPU

acts as an UDP server awaiting for

incoming datagram on local port 80

Note: An unsolicited event +WIPREADY: 1,1

will be received once the UDP socket is ready

for usage

AT+WIPCREATE=1,1,”www.wavecom.com”,

Note: Create the UDP socket on arbitrary free

local port with peer IP and peer port 80 with

communication index = 1 Ù Wireless CPU

acts as a UDP client that can send datagram

towards the remote entity

Note: An unsolicited event +WIPREADY: 1,1

will be received once the UDP socket is ready

for usage

AT+WIPCREATE=1,1,80,”www.wavecom.co

m”,80

Note: Create the UDP socket on local port 80

with peer IP and peer port 80 with

communication index = 1 Ù Wireless CPU

acts as a UDP client and an UDP server : it can

send datagram towards the remote entity and

receiving datagram on the specified local port.

Note: An unsolicited event +WIPREADY: 1,1

will be received once the UDP socket is ready

for usage

AT+WIPCREATE=3,1,80,5,9

Note: Create the TCP server on port 80 with

server index=1 Ù Wireless CPU

acts as a

TCP server : it will from now on spawn TCP

client socket from communication index 5 to 9

Note: An unsolicited event +WIPACCEPT: 1,5

will be received once the TCP server is ready

for usage

AT+WIPCREATE=2,1,”IP ADDR”,80

Note: Create the TCP client on port 80 with

index=1 Ù Wireless CPU

acts as a TCP client

: it can from now on communicate with the

remote specified entity through communication

index 1

Note: An unsolicited event +WIPREADY: 2,1

will be received once the TCP client is ready for

usage

AT+WIPCREATE=4,1,”ftp.wavecom.com”,”a

dmin”,”123456”

Note: Create a FTP session Ù towards the

remote specified FTP server. Communication

index to be used then is 1

Notes:

• The +WIPCREATE command causes the connection and authentication to the FTP server. If

several file uploads and retrievals are required to/from the same server, a single connection with

+WIPCREATE is needed. Then, each file operation will be done (one +WIPFILE command per

operation), and the FTP connection will be released with +WIPCLOSE.

• SIM card is required only if FTP session is established through GSM or GPRS. An FTP session

upon an UART will work without a SIM card.
