I would like to request up-to-date OpenThread RCP firmware images for ConBee II (ConBee 2) and RaspBee II (and RaspBee 2) and that each image and respecitve hardware gets tested and validated with the the Zigbee-on-Host (ZoH) Zigbee stack project for Zigbee2MQTT.
FYI, "Zigbee on Host" (a.k.a. ZoH) is a experimental hardware-independent Zigbee-stack from Zigbee2MQTT developer Nerivec:
https://github.com/Nerivec/zigbee-on-host
It is still experimental but this new fully open-source Zigbee-stack is now usable for non-production as a Zigbee Coordinator for Zigbee2MQTT.
It has been tested with radio microcontrollers from Silicon Labs and Texas Instruments however can be in theory be used with any IEEE 802.15.4-based MCU running OpenThread RCP firmware.
It run on a computer host and uses a Radio Co-Processor (RCP) design design to communication with the MCU running OpenThread RCP firmware via OpenThread Daemon through an SPI interface over the Spinel protocol.
Ping @Haerteleric and @manup (who are Dresden-Elektronik employees that worked on OpenThread RCP firmware).
