Using Reach with Android devices

Some Android devices have battery optimization enabled by default. Make sure you disable it for Emlid Flow to avoid disconnection.

Power up Reach​

tip

You can read more about power supply in the Power supply guide.

To power up your Reach, follow the steps below:

  1. Hold the power button for 5 seconds to turn the unit on.

  2. Wait for about 30 seconds until the Power LEDs will stop blinking and the Network LED stays solid white.


Now you can connect to your Reach.

Connect to Reach​

You can connect to your Reach in two ways:

  • Using the BLE connection option. This is the recommended connection.
  • Using the Wi-Fi connection option. In this case, your device and Reach must be in the same Wi-Fi network.

To connect to your Reach receiver using Bluetooth, follow these steps:

Connecting to Reach via Bluetooth​

note

Make sure your Reach receiver is running firmware version 32.2 or later, and that the Emlid Flow app is updated to version 12.2 or newer on both iOS and Android devices.

  1. Enable Bluetooth on your smartphone or tablet.

  2. Open Emlid Flow. When prompted, tap Configure access and allow both location permissions and precise location. This is required for full receiver functionality.

    note

    Reach prioritizes the current connection when using BLE, regardless of type:

    • If Reach is connected via Bluetooth Classic to third-party software, disconnect it before using BLE in Emlid Flow.
    • If another device is connected to Reach, disconnect it before reconnecting using BLE in Emlid Flow.

    After granting permissions, your receiver will appear in the list. The app will connect to it automatically.

    If you have multiple Reach receivers, tap the one you want to connect to and wait for the connection to complete.

  3. Once connected, check for firmware updates. If an update is available, a red dot will show next to the Settings section. Update the receiver firmware.

    note

    This step is optional, but we recommend updating your receiver regularly to ensure full functionality and access to the latest features. For more details, check out the How to update firmware guide.
