FAQ

Q: Why do I need to authorize the connection to the device twice?

A: First connection: Establishes serial communication with the device.

Second connection: Retrieves the device descriptor to automatically identify ZBDongle-P or ZBDongle-E.

Note: This dual-step process is required because the two dongles use distinct Zigbee protocol stacks.

Q: Can I flash firmware to devices from other brands?

A: Strongly discouraged. This tool exclusively supports SONOFF Dongle.

Risk: Non-SONOFF devices may use incompatible SoCs/firmware configurations, which could permanently brick the device.

Q: The serial port device isn't detected. What should I do?

A: Ensure the device is fully inserted into a functional USB port.
Windows/macOS users: Install the Silicon Labs CP2102 Driver.
Linux users: Most distributions include native driver support.

Troubleshooting Tips:

  • Try a different USB port/cable.
  • Restart your computer if the device remains undetected.
Q: Connection failed - the device is unresponsive!

A: Possible causes:

  • Another program(e.g., ZHA, Z2M, SecureCRT) is using the serial port.
  • Driver conflict or unstable connection.

Troubleshooting Steps:

  • Close all serial port applications.
  • Power-cycle the device: Unplug→Wait 5 seconds→Replug.
  • Click Reconnect.

If the issue persists, kindly post your request for help in the r/sonoffdongle/ subreddit on Reddit, and we will attend to it as soon as possible.

Q: Does this tool support devices running Router firmware?

A: Yes. Devices with Router firmware can still be reflashed, even though their firmware type isn’t automatically recognized.

A: Yes, if the Bootloader is intact:

Use this tool to reflash the correct firmware.
Warning: A corrupted bootloader may require hardware repair.
