Broadcast messaging
In broadcasting, the master sends one dataset to all followers, or a follower sends
one dataset to all other followers (after receiving a token from the master).
The target (Target Grp) is automatically set to 255 denoting all followers.
Note: The master does not receive any data broadcast by the followers.
