I'm running into some issues connecting an Arduino Nano 33 BLE to the app I created with MIT App Inventor. I can successfully scan for nearby devices in the mobile application, but after selecting the desired device from the list, the program remains in the "Connecting" state until it disconnects itself shortly after. However, my Arduino program shows that the connection is made and that data is being advertised. How can I fix this problem? I've attached my App Inventor design below. Any help is much appreciated.
