I am using the library from the following link https://github.com/md-sohrab-alam/android-obd-reader. I followed the same coding as the one display on the read me page but I only get an empty screen. What could be causing this issue. There is no error code in the Run tab.

More details of what hardware and car setup you’re using might help. I suspect though that you’re trying to read engine codes, where the sample is to read head unit (radio) data. – Damon Earl Jan 27 '21 at 01:45

I'm using an ELM327. The app of the listed link, works fine. I just followed the code from the sample app to mine. – John Alvin Joseph Jan 27 '21 at 15:01
