You might want to read my comments on the Bluetooth version at post #113 of this thread: Lets build a 1967 e type together
I hope you have an iPhone as that seems to work better than Android. Please let us know how you get on. Maybe the software is better than I reported more than a year ago. Since mine now works, I haven’t tried to access it using bluetooth for a long time… If you do run into problems, contact me via PM and I will try to help. Good luck!
