Connecting to cyclone bluetooth controller?

How is this done? I have a Samsung Galaxy S4 (old af), and it will detect the controller, pair with it, then nothing happens. Whats going on here?

Is the app you're using from Cyclone compatible with the version of android your device is running?

I had this problem too. There are actually 2 different e-motor apps and one will connect but do nothing. You want this one:

I use I phone but I think they have an android version also. The password to connect to Cyclone drive is "12345678". The app logo you want is:
