TROUBLESHOOTING

BLE SCANNING PROBLEM

Press “scan devices” on the app and wait for 5 seconds for the scan to complete.

CORE BATTERY IS EMPTY

Charge your CORE device for at least 15 minutes.

CORE IS IN OFF STATE

Shake CORE until LED starts blinking to switch it on.

WRONG SMARTPHONE SETTINGS

Make sure Bluetooth and location services are enabled on your phone.

ISSUE WITH SMARTPHONE BLE SUBSYSTEM

Occasionally, the BLE subsystem on the phone crashes. Restart the phone and try again.

ELECTROMAGNETIC INTERFERENCE / TOO MANY BLUETOOTH SIGNALS IN THE SAME ROOM

Go into a less noisy environment and try again. Some phones can only detect a limited number of BLE devices at the same time.

BLE RECEIVER SIGNAL SATURATION

Some BLE receivers cannot cope with too high signal strength. Increase the distance between CORE and smartphone to 1 meter and try again.

RESTARTS

Try switching off your phone's bluetooth, then switch it on again.

Quit the app and reopen it.

Restart your phone.

CORE RESET

Be aware that doing this will reset the device and delete any prior data.

If none of the above work, try to reset your CORE by taking a magnet and moving it across the center of the SKIN side. The green LED will give a feedback indicating that CORE is being reset.

For firmware older than November 2020:

After a reset, CORE will be back into sleep mode: To start broadcasting again you will have to "connect to a charger" and then "shake CORE".
