ESP Zigbee NCP (Espressif ESP NCP host) firmware for ESP32-C6 and/or ESP32-H2?

[Hedda]

@grobasoz have you considered building ESP Zigbee NCP (Espressif ESP NCP host) firmware for ESP32-C6 and/or ESP32-H2 SoCs?

espressif/esp-zigbee-sdk#124

Espressif ESP NCP host firmware builds wanted for testing:

https://github.com/espressif/esp-zigbee-sdk/tree/main/examples/esp_zigbee_ncp

You already built ESP Zigbee RCP firmware but ESP Zigbee NCP is for less complicated projects like ZHA via zigpy to make use of:

https://github.com/grobasoz/zigbee-firmware/tree/master/ESP32-C6/Zigbee_RCP

ESP32-C6 NCP host can be implemented as a single SoC solution while the ESP32-H2 needs another external chip for interface, like for example either USB-to-UART/Serial converter/bridge chip (e.i. CP210x, FT231X, CH9102F or CH340B) to make a simple USB-adapter or a ESP32-C3 for a network-attached adapter (ie. Zigbee remote adapters similar to https://github.com/tube0013/tube_gateways and https://github.com/mercenaruss/zigstar_gateways ).

Looking at recent commits in their esp-zigbee-sdk SDK looks like they have begun working on implementing an NCP host component:

PS: FYI, it looks like Espressif themselves have one of their developers working on a zigpy radio library for esp-zigbee-ncp API/CLI:

zigpy/zigpy-cli#42

zigpy/zigpy#1052

@Hedda - Always good to hear from you :) I started looking into a version of NCP that would work with (Silabs) NCP using a 'C6 but found they were quite different. That was however some time ago so there may have been updates... Will have another look when time permits.

@grobasoz FYI, Espressif has now made an experimental version of zigpy-espzb available in this repo (but it is not yet on PyPI):

zigpy/zigpy-cli#45

@Hedda - Thanks for that - I'll see if I can have a look. Gary.

@grobasoz should this and the others maybe have been closed as ”not planned” instead of as ”completed? Closing as ”completled” mean that they are done while closing as ”not planned” means they will never be done.

[grobasoz]

@Hedda - Yes, should be "not planned" but I couldn't find that option when closing?

[grobasoz]

@Hedda - Options exists on web... will close now, thanks.
