In order for UNDOK to set up a radio which is not currently connected to your Wi-Fi network it requires access to location. Both iOS and Android are unable to provide the SSID of a network device to an app unless the app has access to location. It is only necessary for UNDOK to have access to location while it is being used to set up a radio. Once the radio is set up the access is no longer required. If you continue to give UNDOK access to location you must ensure that Precise Location is enabled.
