TCP Data Transfer Example

AT+MIPCALL=1,"orange","test","test"
OK
+MIPCALL: 172.17.242.86
AT+MIPOPEN=1,1222,"123.245.213.012",1234,0 //Opening socket 1 using TCP protocol, from port 1222,
targeting 123.245.213.012 port 1234
OK
+MIPOPEN: 1,1
AT+MIPOPEN? //Terminal checking the status of socket to be opened (socket 1 opened
OK)
+MIPOPEN: 2 3 4
+MIPSETS=1,340 //Asking the G24 to accumulate 340 bytes on socket 1 prior to sending
+MIPSETS: 0
OK
AT+MI PSE TS?
+MIPSETS: 1 340
OK
AT+MIPSEND=1,"444444" //Sent coded "DDD" string
+MIPSEND: 1,1497 //Free storage in the accumulating buffer
OK
Note: This step can be repeated several times until the buffer is full or until the amount of data

reaches 340 bytes and data pushed into the stack.

AT+MIPSEND? //Checking the size remaining (optional)
+MIPSEND: 1 1497
OK
+MIPPUSH=1 //Terminal asks G24 to flush the buffer in socket 1
+MIPPUSH: 0
+MIPCLOSE=1 //Terminal closes the socket
+MIPCLOSE: 1
OK
+MIPCALL=0 //Terminal hangs up the link
OK

TCP Raw Data Transfer Example (Online Data Mode)

// create a wireless link:
AT+MIPCALL=1,"internetg"
OK
+MIPCALL: 172.17.242.86
// open a socket in Online Data Mode:
AT+MIPODM=1,1204,"123.245.213.12",1205,0
OK
+MIPODM: 1,1
