I have searched around for some documentation on the “Listen For Disconnection” block on thunkable and have not found any. I’m not sure if it’s a new feature to “BLE” or not, but I am getting an error stating “this.manager.onDisconnected is not a function. (In’this.manager.onDisconnected(t)',‘this.manager.onDisconnected’ is undefined).” Any help on this would be great. I’m trying to use this feature so my phone will automatically try to reconnect to the Bluetooth device when it has sensed a disconnection. ---

@brianl Thanks for the update, I just got back from vacation. I still can’t test because of the app crashes. But hopefully that block is working. ---
