Hi, All.  
I trying to create TCP-Server through GSM bearer.

I configure GSM bearer so:  
AT+WIPCFG=1  
AT+WIPBR=1,5  
AT+WIPBR=2,5,5,1  
AT+WIPBR=2,5,15,“10.0.0.50”  
AT+WIPBR=2,5,16,“10.0.0.51”  
AT+WIPBR=4,5,1,“z”,“z”

After 1 ring i receive:  
+WIPBR: 5,0,“10.0.0.50”,“10.0.0.51”,“0.0.0.0”,“0.0.0.0”

So now i can create TCP-server something like this:  
AT+WIPCREATE=3,1,8888,5,5

It all works fine with WipSoft 2.1. After firmware (657f00gg.Q24PL001 1968096 051908 10:44) and WipSoft (3.11) upgrading problems are occured.  
Client is trying to connect with GSM bearer, but it can’t (timeout error).  
I don’t receive any "+WIPBR: " responses from modem. In some time i get “+CME ERROR: 809”

Is it bug in new WipLib or I do something wrong with bearer as server configuration?

AT+WIPBR=4,5,1,“z”,“z”

OK

AT+WIPBR?

+WIPBR: 5,0

Is it ok? Or must be “+WIPBR: 5,1”?
