Thank you so much! If it doesn't work with that app, please try this: https://play.google.com/store/apps/details?id=com.giristudio.hc05.bluetooth.arduino.control It works great!

Thank you, @syedmahamood. I was able to duplicate this project. I added in the code, to change the Serial.print("/n") to Serial.println() -- this worked well and in the Arduino Serial Monitor, the data used from the app displayed. Also, as of December 2022, the Arduino Bluetooth Control app has changed. There is no 'button 0', so I modified the code for button 2 so that the on the "Buttons" page of the app I could switch the light on/off with Button's 1 and 2. Thanks again.

Any idea why my LED isn't lighting, despite the RX light blinking whenever I click the off/on button on the app??

This is the easiest app to figure out how to use. Thank you very much for sharing it. :)
