How to connect RTK receiver to iOS device (iPhone or iPad) via BT+BLE Bridge?

In this tutorial you will learn how to connect your GNSS/RTK receiver (simpleRTK2B, simpleRTK3B or any other receiver) to any iOS device.

With ArduSimple BT+BLE Bridge module, you will be able to connect your ArduSimple receiver to an iOS device (iPhone, iPad or iPod touch) via Bluetooth low energy (BLE) and use it with compatible software.

The ArduSimple BT+BLE Bridge module acts like a bridge/tunnel sending any incoming data from your GNSS receiver towards the listening device and sending all incoming data from your BT/BLE device to your GNSS receiver.

Currently, the number of applications that supports external GNSS receiver connecting via Bluetooth on iOS is still quite limited. In this tutorial we use SW Maps because at this moment it is the only free app available at App Store.

But we hope that with this new solution more and more developers will decide to upgrade or create new iOS apps that make use of centimeter precision.

Required hardware:

Required software:

  • SW Maps (if you do not have it installed, you can download it from App Store)

How to connect ArduSimple RTK receivers to iOS smartphone or tablet via Bluetooth?

  3. Press Connect.
