Route record (TZ-922) #359

Closed HOSTEER closed 4 months ago

HOSTEER commented 6 months ago

Is your feature request related to a problem?

Not having access to the available devices, and their related path cost and relay count

Describe the solution you'd like.

A get function to look out the route record data, table 3-59 Route Record Table Entry Format from rev 22 of Zigbee specification

Describe alternatives you've considered.

use a Zigbee sniffer to guess what should be the data in the route record by looking the route request and reply frames

Additional context.

When benchmarking the latency of the data transission across mesh network it's dificult to know the number of router a packet is passing through just by looking the Zigbee sniffer

@HOSTEER ，

The esp_zb_nwk_get_next_route() seems to meet your requirement.

HOSTEER commented 5 months ago

The esp_zb_nwk_get_next_route() is missing some variables of the route record. There is the destination adress for sure but the relay count and the path are missing.
