 ## Connecting external GPS
-External GPS can be connected to the <MobileAppNameShort /> via [Bluetooth](#bluetooth-connection-android-only) or a [Network provider](#network-provider-connection). We recommend using one of these options as they provide more data, such as HDOP and fix quality (see [position variables](../../layer/variables/#position-variables)). Also, the <MobileAppNameShort /> will report which device is used and take care of reconnecting in case of lost connection.
