CC110L: Broadcast message to multiple peripheral devices

Nick Trevethan0
Prodigy 10 points
Part Number: CC110L


Is there a mechanism to allow one "master" to broadcast to multiple peripherals simultaneously using the CC110L? I would like to send the same message to several "peripheral" devices and have them all receive at (roughly) the same time. I am attempting to provided a synchronization signal to multiple endpoints simultaneously. This is for humans to be synchronized (similar to a metronome) so the timing requirements aren't too strict - the timing difference needs to be in the ~10-20 ms ballpark. Is there an "all call" addressing scheme? Can I force the peripherals to use the same address in firmware (assuming there is no acknowledge signal)?

    Nick,

    Yes this is possible.

    The CC110L supports addressing, but this feature can also be turned off. If you do not have addressing turned on, all the nodes will attempt to receive a packet and most of them will receive the packet. They will receive the same packet at the same time, but you will find that a based on the link budget some of the nodes will miss a packet here and there (based on the PER). Therefore I would recommend that you setup a system where you send more messages than what you need. I have seen systems where they send 4 times as many packets to ensure that all of them will get one packet in a certain time interval.
