ZStack broadcast without joining a PAN

TMA6611

Hi all,

I would like to use ZStack to transmit a broadcast message from End Devices to Routers/Coordinators without joining a network.

I did a quick test to kill the joining process when my application starts and send broadcast message with this destination address:
dstAddr.addrMode = (afAddrMode_t)AddrBroadcast;
dstAddr.endPoint = AF_BROADCAST_ENDPOINT;
dstAddr.addr.shortAddr = NWK_BROADCAST_SHORTADDR_DEVALL;

Doesn't work and I guess I need to specify MAC_PAN_ID_BROADCAST to make sure all PANs are included?

This is probably not very Zigbee-like and might flood the network if not handled with care... but is it possible?

Regards, TMA

Hi TMA,

Personally, I think that It's impossible to send a broadcast message to any devices without joining a network because you need to be logged with a coordinator. Otherwise, the devices will drop every message which come from out the network.

Hi Manuel,

Did some further review and forum reading, especially on the INTER_PAN feature but seems like there is no way to send application messages like this.

Thanks for the reply.

Hi TMA,

I didn't think in INTERPAN feature... But I also believe that you have to be validate with a coordinator in each PAN. Otherwise, the messages will be dropped by the network devices.
