Hi i wanted to know if it would be possible using an iOS or android app through Bluetooth, to modify the Redbear Duo Wifi IP, SSID and password in order To connect to an access point.
Thank you very much for any assistance you can provide
Yes, it is. Please refer to this guide. Also you can design your own protocol to set these kind of informations, in this case you need to get familiar with the BLE APIs and WiFi APIs (see here).
