MQTT Firmware for KC868-H4 and H8

[admin]

now KC868-H32B and KC868-COLB already have new firmware support MQTT. But unfortunately, only "B" series product can support MQTT, because we have try ,but old version have not enough hardware resource to support MQTT function. But if you want to replace with your old controller with new version, we have discount for old user, you can contact with online store seller.
