Spirit System

This week I bought a BT-Modul.
I installed the APP (version 3.0) on my Handy SAMSUNG S6.
I choose the correct BT-channel and try to connect to the new BT-modul.
But I got a fault-message:

--------------------------------
Firmware version does not match
with the software version.

Firmware: 2.8.0
Software: 3.0.X
OK
--------------------------------

What can I do ?

Thanks for help

Please install Android app, version 2.8.0.

You can download it from here:
