I have the XU-Z11 XStick2. I bought it for controlling Zigbee Home Automation devices, but no software seems to be able to connect to it. I have XCTU installed, which detects no firmware on the device and can't seem to find any firmware to flash onto it. I would like to flash the coordinator profile on there, but none of the firmware I can find mentions the XStick. How can I put the coordinator firmware on it?
