Wifi Shield v2.0 stuck in WPA Mode and WPS Mode

Hi Everyone,

I used to have two wifi shields v2.0 working properly with an mbed. However now one of them is stuck in the wpa_app, and the other is stuck in WPS mode.

I have tried every reboot/reset/etc that I could find for the RN-171. I cannot update the firmware properly since the one in the wpa_app does not recognize the ‘ftp’ command, and the one in the WPS mode doesn’t listen to commands at all.

Has anyone else had this issue? Do you know of any other reset commands besides:

  • Power cycle
  • the command: “factory RESET”
  • toggling the IO9 pin

Thanks in advance for your help!
