set Group
Make a program have the group ID you tell it for sending and receiving
with radio.
radio.setGroup(0);
A group is like a cable channel (a Calliope mini can only
send or receive in one group at a time). A group ID is like the cable
channel number.
If you do not tell your program which group ID to use with this
function, it will figure out its own group ID by itself. If you load
the very same program onto two different Calliope minis, they will be able
to talk to each other because they will have the same group ID.
Parameters
Default radio group
If you haven’t set a radio group for the Calliope mini, it will use one selected randomly. If you are transmiting data to a Calliope mini that has a different hardware version from the sending Calliope mini, it will select a random default group that is not the same as the other Calliope mini. To be certain that your program will send or receive data using the same radio group, you will need to first choose and set a radio group for your program if you want it to work between different versions of the Calliope mini.
Simulator
This function only works on the Calliope mini, not in browsers.
Example
This program makes the group ID equal 128.
radio.setGroup(128)
