Wiffi210 connection & disconnection (urgent)

Question

Hi, What is the proper way of disconnecting from a Network?? I set up my WIFI-module as a server and connect to a PC in Adhoc-mode. I use these commands: Connect to WiFi-network: AT+WWPA=password Disable DHCP: AT+NDHCP=0 set module Ip-Address and Gateway IP: AT+NSET=192.168.1.1,255.255.255.0,192.168.1.2 set Wifi-parameters for auto-connect: AT+WAUTO=2,MYadhocNetwork,0 Connect: ATA Connection is made…< Now in data-mode, i cannot send any more commands to the module. Now if want to disconnect again… Question1: is the proper way of disconnecting, to send “+++” ?? do i have to issue a AT+XDUM=0 command first everytime? Question2: If i connect my computer to the adhoc-network first, it says “waiting for user”. As soon as i connect the WIFI-module (with ATA), the connection is made and the computer says “connected”. Everything is fine! But if i connect the module first and then the computer, no connection is made. The computer says “waiting for user…” and nothing more happens. Can i force a connection to be made? i could use the AT+PING command to see when the computer is connected and then issue a ATA command, but that won’t work since i’m not connected to the computer before ATA-command Question3: Can i send AT+Ping commands while in data-mode? The module is inresponsive in data-mode, so i’m not sure how to send additional commands without first exiting data-mode (with +++), which disconnects the server-client connection. Note: i’m using a dfRobot Wifi-shield v2.2.Tried getting help from dFrobot, without success (yet)

Hello hobbex You can’t issue at-commands in data-mode. If you want to disconnect it or issue additional command, WizFi210 should be transited into using “+++”. Steve

Thanks Steve, So, what about my Question#2 regarding the adhoc-connection procedure?

Here is my test scenario. configure WizFi210 as ad-hoc mode(ssid : dddddd) AT+NSET=192.168.12.254,255.255.255.0,192.168.12.1 at+wd at+wa=dddddd (just test ssid) configure PC as ad-hoc mode(ssid : dddddd) In this step, I used with static ip. Then the ping-test worked well. How about test it again with another wireless utility(not zero configuration). I guess the problem is related with windows-wifi-configuration-program(zero configuration). Steve
