[REQUEST] Zigbee NCP (Network Co-Processor) mode support? (TZ-374)

[Hedda]

This feature request is also related to espressif/esp-zigbee-sdk#124

The current release only has ZBOSS RCP, but our old implementation uses ZBOSS NCP host.

The ZBOSS libraries for the NCP host include the following stack layers:

Zigbee cluster library (ZCL)
Commissioning logic (part of ZDO)
ZBOSS NCP serialization protocol
ZBOSS platform support layer for Linux-based OS

Since you use ZBOSS already if it is possible that we can use our old implementation with ZBOSS NCP host or if we need to rewrite it against esp-zigbee-sdk. It would be enough for us if we could get the ZBOSS NCP SoC firmware files.

Can you please consider adding support for ZBOSS NCP host for Zigbee NCP (Network Co-Processor) mode?

Currently is seems like esp-zboss-lib only support Zigbee via a RCP (Radio Co-Processor) mode and no support for ZBOSS NCP host?

See example:

https://developer.nordicsemi.com/nRF_Connect_SDK/doc/zboss/3.11.2.0/zboss_ncp_host_intro.html

https://developer.nordicsemi.com/nRF_Connect_SDK/doc/zboss/3.11.2.0/zboss_ncp_host.html

ZBOSS NCP host as Zigbee NCP mode is required to implement support in the zigpy-zboss radio library for zigpy as a Zigbee Coordinator adapter interface which is used by the ”ZHA” Zigbee gateway integration that is built-into Home Assistant:

ZBOSS NCP support would probably also be prefered for Zigbee2Tasmota (Z2T) compatible in Tasmota:

arendst/Tasmota#20045

For reference, Tasmotas's Zigbee2Tasmota (Z2T) already supports Texas Instruments ZNP and Silicon Labs EZSP Zigbee stacks/interfaces with respective Zigbee Coordinator adapter running Zigbee firmware in NCP (Network Co-Processor) mode:
