1. Make sure Bluetooth is turned on and your device is close by. Some smartphones ask for your permission to connect to a device, this serves as a safety check.
  2. Make sure your device's location service is enabled. (This does share your physical location, it is so the devices can connect with each other.)
  3. Make sure to have a stable Wi-Fi-connection (or 4G) (necessary to transmit the results)
