Use the Explicit Addressing Command frame - 0x11
devices in the network. Sending ZDO commands with the Explicit Transmit API frame requires some
formatting of the data payload field.
When sending a ZDO command with the API, all multiple byte values in the ZDO command (API
payload), for example, u16, u32, and 64-bit addresses, must be sent in little endian byte order for the
command to be executed correctly on a remote device.
For an API XBee to receive ZDO responses, set
frame.
The following table shows how you can use the Explicit API frame to send an "Active Endpoints"
request to discover the active endpoints on a device with a 16-bit address of 0x1234.

Offset Description
3 0x11
4 Identifies the data frame for the host to correlate with a
subsequent transmit status. If set to 0 , the device does not send a
response out the serial port.
MSB first, LSB last. The 64-bit address of the destination device (big
5-12
endian byte order). For unicast transmissions, set to the 64-bit
address of the destination device, or to 0x0000000000000000 to
send a unicast to the coordinator. Set to 0x000000000000FFFF for
broadcast.
13 MSB first, LSB last. The 16-bit address of the destination device (big
endian byte order). Set to 0xFFFE for broadcast, or if the 16-bit
14
address is unknown.
15 Set to 0x00 for ZDO transmissions (endpoint 0 is the ZDO
endpoint).
16 Set to 0x00 for ZDO transmissions (endpoint 0 is the ZDO
endpoint).
