A custom firmware on DF1 device allows toggle of wireless modes for regulatory testing.
There are 3 different modes, each of which targets low,medium,high frequencies within the bluetooth band.

These modes are:
* TX Continous Wave at 2402, 2440, 2480
* TX Modulated at 2402, 2440, 2480
* RX On at 2402, 2440, 2480

These modes can be activated by simply tapping on the device as shown on the video.
The accelerometer detects a "tap", and will cycle through 3 frequencies for each of the 3 modes.
