+WIPDATA indication issue


#1

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,804
41

< 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

Hi,
Are you using outdated FW?
Otherwise try the latest FW and check if it solves the problem.

Dear,

I upgraded firmware L22_00gg.WISMO218 281210 and the module worked as my expectation.
Again thanks lotam too much : ).
