i tried to run this projekt, but have errors in serial monitor when i use the app and read pricelist, or ty to register cards.

Serial monitor prints hiroglyphs. Mastercard was exceptet via serial monitor, nothing more happend. i wrote an email to heise/ ct' with no answer.

That sounds as if your baud rate is not set correctly.

I dont think so, cause the other stuff works a bit...
or can i use two bauds?

[Exorzist6666]

Okay, i fixed the problem. readout baud rate of hc-05, and correct it in sketch, there have been two bauds.
no it connects and print in serial.
But new problem with the app. i cant register cards over the app, ang get them listet in the app to charge.

and what means the text in serial log... ?
And what means the app stuff?
Why are the cards in the price list?
