Bluetooth Android App

[Zeph]

Hi,

I want to be able to connect my android phone to the BeagleBone Black Wireless and use an app on my phone that will function as a joystick and send values over bluetooth to the beaglebone. I am looking for something similar to Blue Dot for the Raspberry Pi:

https://github.com/martinohanlon/BlueDot

Does anyone know of a similar app I can use for the BeagleBone Black? If I were to create the app myself, would it be difficult to interface the BBB bluetooth with the android app? Has anyone had success with a similar project? If you have can you please share any resources used for establishing the bluetooth connection and sending data back and forth.

Thanks!

BlueDot, itself, is a Python module, and

debian@beaglebone:~$ sudo pip3 install bluedot

Installing collected packages: bluedot
Successfully installed bluedot-1.3.2

What may NOT function is the interface to the bluetooth radio (I can't
test as I have BB Black, NO WIFI).

Why bluetooth?

Isn't WiFi more easy/powerfull? Ie. a JavaScript app in a browser sending to a fcgi client on the BBB.
