Wireless communication
Dongle and modules communicate wirelessly using radio signals.
Channels: The radio signals can be on different channels, each of the channels is indicated
by the Dongle’s or module’s LED color. If a Dongle and a group of modules are on the same
channel they are able to communicate.
Color pairing: The color on the modules and Dongle indicates the radio channel. To pair
modules with a Dongle simply match the color by pressing their buttons.
Interference: Several Dongles and robots can be on the same channel, however,
performance will gradually decrease due to interference. In environments where many users
work with Fable robots interference can be reduced by distributing evenly on the different
channels.
