1. Download [SW Maps](https://play.google.com/store/apps/details?id=np.com.softwel.swmaps). This may not be the GIS software you intend to do your data collection, but SW Maps is free and makes sure everything is working correctly out of the box.
4. Please note the four-digit code in the top left corner of the display (**B022** in the above example). This is the MAC address you will want to pair with.

5. From your cell phone, open Bluetooth settings and pair it with a new device. You will see a list of available Bluetooth devices. Select the ‘Facet Rover-3AF1’ where 'Facet' is the type of device you have (Surveyor, Express, Facet, etc) and 3AF1 is the MAC address you see on the device’s display.

7. Press the SW Maps icon in the top left corner and select Bluetooth GNSS. You should see the ‘Facet Rover-3AF1’ in the list. Select it then press the ‘Connect’ button in the bottom left corner. SW Maps will show a warning that the instrument height is 0m. That’s ok.

9. Now put the device outside with a clear view of the sky. GNSS doesn’t work indoors or near windows. Within about 30 seconds you should see 10 or more satellites in view (SIV). More SIV is better. We regularly see 30 or more SIV. The horizontal positional accuracy (HPA) will start at around 10 meters and begin to decrease. The lower the HPA the more accurate your position. If you wait a few moments, this will drop dramatically to around 0.3 meters (300mm = 1ft) or better.
You can now use your RTK device to measure points with very good (sub-meter) accuracy. If you need extreme accuracy (down to 10mm) continue reading the [RTK Crash Course](https://docs.sparkfun.com/SparkFun_RTK_Firmware/intro/#rtk-crash-course).

The software options for Apple iOS are much more limited because Apple products do not support Bluetooth SPP. That's ok! The SparkFun RTK products support Bluetooth Low Energy (BLE) which *does* work with iOS.

5. Corrections will be downloaded every second from PointOneNav using your phone’s cellular connection and then sent down to the RTK device over Bluetooth. You don't need a very fast internet connection or a lot of data; it's only about 530 bytes per second.
As soon as corrections are sent to the device, the Crosshair icon will become double and begin flashing. Once RTK Fix is achieved (usually under 30 seconds) the double crosshairs will become solid and the HPA will be below 20mm. You can now take positional readings with millimeter accuracy!
