Dear all,
I’m using Wismo228 module to implement GPRS feature. I have to use both online data mode and at mode ( for receiving SMS ). Then I swap between these modes. The problem that I meet is: There is only one time I can receive TCP package +WIPDATA indication when unit is in AT mode. I switch to online data mode, read the data and go back to AT mode. After that I don’t receive any +WIPDATA indication. Even there is coming data from the server. I test many time and all are same situation. Can anyone help me please ?
I send the log below:
AT+WIPCFG=1
OK
AT+WIPBR=1,6
OK
AT+WIPBR=4,6,0
OK
AT+WIPCREATE=2,5,“www.teamtekbox.com”,30175
OK
+WIPREADY: 2,5
AT+WIPDATA=2,5,2
CONNECT
$FRLIN,anh,SMZ50 <-- login to server
$FRSES,80441
< transfer data to server >
+++ <— switch to AT mode
OK
…
<from the server I send “hello” >
+WIPDATA: 2,5,5 <-- there is TCP package indication
AT+WIPDATA=2,5,2
CONNECT
hello
+++ <— switch to AT mode again
OK
…
< from the server I send “hello” >
AT+WIPDATA=2,5,2
CONNECT
+WIPPEERCLOSE: 2,5
OK
