Hi Terence,

Yes, when using the address 0xFFFF (or ZB_NWK_BROADCAST_ALL_DEVICES in our SDK), it should be sent to all devices.

Best regards,

Hi Marte,

Correct me if I'm wrong. So by setting the the destination address of a command to 0xFFFF, it will send it to all devices?

Regards,

Terence

Hi Terence

It would help to know what you want to achieve with this. Why do you want the Zigbee device to send a beacon to the end device? Beacon requests and responses are used for network discovery, where the device that wants to connect to a network sends out a beacon request. This request is received by a Zigbee coordinator or by Zigbee routers, and these devices will then send a beacon response back to the first device.

Broadcasts are used to send messages to all devices in the Zigbee network. The transmission is sent once by the device that initiated the message, and is then repeated by the coordinator and routers so that it propagates through the network. In order to broadcast a message you'll have to use one of the broadcast addresses. The different broadcast address options for our SDK, which can also be found here, are:

Enumerator	Address	Description
ZB_NWK_BROADCAST_ALL_DEVICES	0xFFFF	All devices in PAN
ZB_NWK_BROADCAST_RX_ON_WHEN_IDLE	0xFFFD	macRxOnWhenIdle = TRUE (all non-sleeping devices)
ZB_NWK_BROADCAST_ROUTER_COORDINATOR	0xFFFC	All routers and coordinator
ZB_NWK_BROADCAST_LOW_POWER_ROUTER	0xFFFB	Low power routers only
ZB_NWK_BROADCAST_RESERVED	0xFFF8	Reserved value
