Installation is very simple:
- Download the .apk file on your Android device and tap the icon to install it.
- Power up the CHM.
- Activate the Bluetooth connection on the Android device and pair it with the CHM.
- Launch the application, tap on connect and choose the CHM Bluetooth connection from the list.
N.B.:
This application is very low profile, you can leave it installed on your phone, no one would ever be able to guess what it really is for.
It was built using MIT App Inventor. In the true spirit of the CHM project, the code is of course open source.
