Been trying to figure this out for some time now. I can’t connect android to controller. Ok so I’m using the app from the group. All works well on 5.8 but when I switch to 2.4 I can’t connect android to controller if controller is already connected to spark. If the spark is off I can connect controller but as soon as controller connects to spark at 2.4g android can no longer see the controller. It’s driving me nuts! Does anyone have a solution? Many thanks!
