I am trying to create an app that will display data transfered from the arduino over bluetooth. I am using a H3 bluetooth chip connected to an arduino uno using pins TX and RX (1, 0).
Everything works fine except the data sent from the arduino IDE will not display on the app. It reads undefined.
Images attacted incluse arduino code, screen1 where the ble connects and screen 2 where I am trying to get the data displayed.
Any help is much appreciated!
