Hello, I have this app that I have created. The bluetooth part that connects to the arduino worked just fine just a few days ago, once I have added more components to the app itself something happened when I tried to test it again. My whole app still can connect to the hc-05 bluetooth but whenever the tx rx is plugged into the arduino board, the app just freezes and crashes. It only freezes and crash when the tx and rx is plugged into the board... i'm not sure what to do....
