No this is not necessary, please find below the only two things you should take care of:  

  1. Make sure your Bluetooth is on and that your phone is close enough to the device. Some smartphones ask for your permission to connect to a device, this serves a safety check.
  2. Make sure your device's location service is enabled. (This does share 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).
