Explicit Addressing Command frame - 0x11
Description
This frame is similar to Transmit Request (0x10), but it also requires you to specify the application-
layer addressing fields: endpoints, cluster ID, and profile ID.
This frame causes the device to send payload data as an RF packet to a specific destination, using
specific source and destination endpoints, cluster ID, and profile ID.
n For broadcast transmissions, set the 64-bit destination address to 0x000000000000FFFF .
Address the coordinator by either setting the 64-bit address to all 0x00s and the 16-bit address
to 0xFFFE, or setting the 64-bit address to the coordinator's 64-bit address and the 16-bit
address to 0x0000.
n For all other transmissions, setting the 16-bit address to the correct 16-bit address helps
improve performance when transmitting to multiple destinations. If you do not know a 16-bit
address, set this field to 0xFFFE (unknown). If successful, the Transmit Status frame (0x8B)
indicates the discovered 16-bit address.
You can set the broadcast radius from 0 up to NH to 0xFF. If set to 0, the value of NH specifies the
broadcast radius (recommended). This parameter is only used for broadcast transmissions.
You can read the maximum number of payload bytes with the NP command.
Note Using source routing reduces the RF payload by two bytes per intermediate hop in the source
route.

The following table provides the contents of the frame. For details on the frame structure, see API
frame format.
Frame data
fields Offset Description
Frame type 3 0x11
Frame ID 4
Identifies the data frame for the host to correlate with a subsequent
ACK. If set to 0, the device does not send a response.

Address
5-12
MSB first, LSB last. Set to the 64-bit address of the destination device.
Reserved 64-bit address for the coordinator = 0x0000000000000000
Broadcast = 0x000000000000FFFF

LSB

Set to the 16-bit address of the destination device, if known. Set to
0xFFFE
if the address is unknown, or if sending a broadcast.
