Signal Mapping using RTLSDR Scanner and GPS on an iOS Device

Recently we posted how RTLSDR Scanner has been updated to allow interfacing with a GPS device. This allows you to make signal strength maps by driving around and recording both signal strength and GPS location together.

As most people don’t have a dedicated GPS device, Reddit user soooooil has put together a short guide on how he was able to use his iPhone as the GPS device and interface it with RTLSDR Scanner.
