Transmission, addressing, and routing ZDO transmissions

a sequence number of a request. The remaining bytes are set as defined by the ZDO. Similar to a ZDO
request, all multi-byte values in the response are in little endian byte order.
Example 1: Send a ZDO LQI request to read the neighbor table contents of a
remote
Looking at the ZigBee specification, the cluster ID for an LQI Request is 0x0031, and the payload only
requires a single byte (start index). This example sends an LQI request to a remote device with a 64-
bit address of 0x0013A200 40401234. The start index is set to 0, and the transaction sequence
number is set to 0x76.

Description
This API frame sends a ZDO LQI request (neighbor table request) to a remote device to obtain data
from its neighbor table. You must set the AO command correctly on an API device to enable the
explicit API receive frames to receive the ZDO response.
Example 2: Send a ZDO network Address Request to discover the 16-bit address of
a remote
Looking at the ZigBee specification, the cluster ID for a network Address Request is 0x0000, and the
payload only requires the following:
