Flash Sonoff on the Zigbee Dongle Plus

The easiest and most reliable is to just use Python (you can use Windows or Linux, does not matter). I used Windows.

• Get the dongle firmware for the Sonoff Zigbee Dongle Plus here: (read to make sure you download the correct firmware)
  • https://github.com/Koenkk/Z-Stack-firmware/tree/master/coordinator/Z-Stack_3.x.0
• Download and install Python (on Windows it’s just Next, Next, Next, Finish. Nothing special)
• Install the following libraries:
  • pip install wheel pyserial intelhex python-magic
• Download the Windows drivers for the Zigbee Dongle Plus and update them in device manager:
  • https://www.silabs.com/developers/usb-to-uart-bridge-vcp-drivers?tab=downloads
• Download the bootloader for the Zigbee Dongle Plus here: ((you can download the entire repo)
  • https://github.com/JelmerT/cc2538-bsl

Now that you have all the prerequisites done, plug in your dongle. No need to open it up and press the button to get it into bootloader mode:

• Replace COMXXX with your actual COM port number.
• I suggest renaming the dongle firmware you downloaded to something simpler.

python cc2538-bsl.py -p COMXXX -e -v -w --firmware.hex
