When Aurora is misbehaving (or not behaving at all), there are a few things you can try to whip it back into shape:
On the back of Aurora's case (you'll need to remove the sensor band to see it), there is a small hole roughly the diameter of a paper clip. Find something small enough to insert into this hole and gently apply pressure. You should be able to feel the resistance of a tiny button being depressed. This button can sometimes be slightly misaligned with the hole and/or wires can get in the way, so be sure to reposition the paper clip until you are confident you are actually making contact with the button. If Aurora is on while you hit the reset button, you should hear the unit boot up again after the button is released. Resetting the Aurora in this way can help it recover from many different situations so it's a good first step in the troubleshooting process.
SD Card Format
The Aurora relies on an onboard SD card for many of its features. Unfortunately, SD cards are notorious for becoming
corrupted or damaged. They can also be jolted slightly out of place due to a hard fall or constant vibrations from
the internal buzzer. If this has happened to your card, many Aurora features will no longer work properly. The first
step for recovering from such a situation is to perform an SD card format. Aurora Desktop provides a way to carry out
this format in the top menu under
Aurora -> Format SD Card. If this process is successful, Aurora will reboot with
an extended start up chime. The CLI command sd-format can also be used. Using Storage
Mode to format the SD card is not recommended.
If you are unable to format the SD card using the above method, the next best way is to simply open up the Aurora case and use a desktop computer to format the card as you would any other USB thumb drive. Opening the case is fairly easy with a little bit of patience. This video goes over the steps. Once the case is opened (make sure Aurora is off), you can remove the SD card and format it using a computer with a microSD slot or by using a cheap USB SD card reader.
If the formatting doesn't work, replacing the SD card altogether is worth a try if you have a spare SD card laying around.
Any SD card should do, just make sure to perform a format operation on the card the first time Aurora boots up with the new
card. Again, this can be done using Aurora Desktop or by manually running the command sd-format.
It is also recommended to run the command sd-test to make sure read/write speeds are
If the above steps don't seem to help, never fear! First, be sure to read through the FAQ which goes over a few specific problems and potential solutions. Second, get in touch with the Aurora Team either on Slack (preferred) or at firstname.lastname@example.org. Be sure to mention that you've tried all the above steps first!
