The IsPaired function checks if Bluetooth device with name is on the paired devices list of our phone/tablet. Returns “true” or “false”.
paired = nxt.IsPaired( name );
function OnStart() { nxt = app.CreateNxt(); deviceName = "myNXTbrick"; paired = nxt.IsPaired( deviceName ); app.Alert( "Bluetooth device " + deviceName + (paired ? " is " : " is not ") + "paired." ); }
