why q24plus sending me “error” ,when I issue " AT+WIPBR=2,6,17,“192.168.0.1"” ???

Because…it can’t !

The wipSoft document has clearly stated :

Caution: The options WIP_BOPT_IP_DST_ADDR, WIP_BOPT_IP_DNS1 and WIP_BOPT_IP_DNS2 are “read only” for GPRS/GSM client

thank you wallace!

I think i need to go back to read the “… user guide” clearly. :cry:
