Wireless Communication
The hub and modules communicate wirelessly using radio signals.
Channels: The radio signals can be on different channels; each of the channels is indicated by the hub’s or module’s LED
color. If a hub and a group of modules are on the same channel, they are able to communicate.
Color pairing: The color on the modules and hub indicates the radio channel. To pair modules with a hub, simply match
the color by pressing their buttons.
Interference: Several hubs and modules 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 users
evenly on different channels.
