Multi Tool - Ethernet

  1. Download latest Zigbee firmware. UZG-01-T Adapter is based on CC2652P from Texas Instruments. Firmware's are based on Z-Stack. You can see the best one here Koenkk Z-Stack firmware on Github.

    Danger

    Currently we are moving to new Texas Instruments Chip - CC2652P7 what will support up to 300 devices
    First users of UZG-01-T are still using CC2652P2 chip

    Choose correct firmware:

    UZG-01-T - Use firmware with a tag "..launchpad_coordinator_";
    UZG-01-T v0.2+ - Use firmware with a tag "CC1352P7";

  2. Download ZigStar MultiTool - choose the right version for your OS;

  3. Connect your UZG-01-T and PC with flashing firmware to the same LAN network over ethernet (cable) connection. It is important, as because WiFi can have some delays - it is incompatible for flashing. Flashing should be done only through ethernet connection;

  4. Open Flashing tool and make te following settings:

    • IP address and port of your UZG-01-T will be identified automatically 192.168.110.122:6638 (1)

      1. 192.168.110.122 is an IP address and 6638 - port

    • click button ... and select your Zigbee firmware, downloaded at stage 1;

    • Put active checkboxes Erase, Write, Verify, and Auto BSL;
    • Press Start button

    Multi-Tool flasher - finish flashing

    Warning

    Zigbee connectivity (e.g. Zigbee2MQTT or ZHA) should be disconnected. Flashing is impossible when the adapter is in active state.

    Danger

    It is crucial that you download the correct firmware for your gateway as using the wrong firmware will disable the BSL and you will need an external debugger / programmer to flash your gateway again.

  5. Wait until the process is completed: the progress bar contains the message "100%" and below text All is Ok. Restarting Zigbee. Flashing takes about 8 minutes;

  6. That is it. Flashing is done. You can use your device now with the new Zigbee firmware. Proceed with installation
