Topic: Connection is established, but interface version is not supported
Hello,
First I apologize for my bad English ...:D
In the app I always get this error message "Connection is established, but interface version of device is not supported by app. Update the application.".
However, the app is up to date (I have the free version).
What can I do about this error message?
I have the Arduino Uno and the HC-05 Bluetooth module.
