communication link
The wireless communication link operates in the 2.4 GHz
ISM band using GFSK (Gaussian frequency-shift keying),
and a proprietary bidirectional communication protocol.
It continuously switches between channels to avoid
interference on any specific channel.
Bluetooth Low Energy also operates in the 2.4 GHz ISM
band, using frequency hopping over 37 channels to combat
interference.
