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:
[64-bit address] + [Request Type] + [Start Index]
This example sends a Network Address Request as a broadcast transmission to discover the 16-bit
address of the device with a 64-bit address of 0x0013A200 40401234. The request type and start
index are set to 0, and the transaction sequence number is set to 0x44.
