How to reset or update the firmware on your doppel


You can check whether your doppel is running the most recent firmware (the code that runs the motor) on the ‘Settings’ page on the app. Press ‘Update’ if it shows your firmware is out of date. It’s important that your doppel is running the most recent version of the firmware.

It can take a few minutes to update the firmware so be patient, and do not close the app while the update is ongoing.

Closing the app when an update is taking place can stop the touch gestures from working, and can sometimes stop doppel from buzzing when it’s placed in the charging base.

If you do accidentally close the app whilst doppel is updating, go back to the ‘Update firmware’ button on the ‘My settings’ page of the app and start the process again. It should then connect and update as before. You may need to try this more than once.

You can reset the firmware at any point. This is the equivalent of turning doppel off and on again and can help with some troubleshooting issues.



 

Troubleshooting

My firmware update is taking more than a few minutes

A firmware update should only take a few minutes. If it's ‘hanging’ or is stuck on the loading wheel or loading bar then it’s likely that your phone and doppel have become unpaired before the update completed.

If the update did not complete, you might notice that your doppel’s touch controls are unresponsive, or that it doesn’t buzz when you put it on the charging base. Don’t worry, if this happens it's because your doppel is now stuck in 'DFU bootloader mode' -  it's essentially sitting in a state where it's waiting for information.

If this happens, first close the app, then open it again and try and scan for your doppel on the My doppel page. The app should find your doppel. Once paired, navigate to My settings and run the firmware update/reset again. This should solve the problem.

If this doesn't work, or the firmware update keeps failing, please get in touch and let us know. Please also include which phone make/model you have and which operating system you’re running.

I’ve received the error message ‘Fatal: Not supported, on operation start DFU update’

If this happens, your doppel is stuck in ‘DFU bootloader mode’ - usually as a result of a failed firmware update or reset.
