I just used Wifi RS21 to jion an access point. When I had a good SSID and Password, it worked well. But once I used wrong password, when reached to Wifi.Join(info,“passwoed”, EMX will totally block, nothing can be processed.
Is it an issue from low level code of RS21 dll?
Thanks

Are you using WEP encryption with Ad-Hoc? If yes, then this must be it. It is the redpine module.

Actually I am using WEP+AP. So are you saying change to WPA? Any other wifi module better than redpine?
