ArcGIS Survey123
ArcGIS Survey123 is a popular offering from Esri that works well with SparkFun RTK products.
ArcGIS Survey123 connects to the RTK device over TCP. In other words, the RTK device needs to be connected to the same WiFi network as the device running ArcGIS. Generally, this is an iPhone or iPad.
!!! note The iOS hotspot defaults to 5.5GHz. This must be changed to 2.4GHz. Please see Hotspot Settings.
The RTK device must use WiFi to connect to the data collector. Using a cellular hotspot or cellphone is recommended. In the above image, the device will attempt to connect to iPhone (a cell phone hotspot) when WiFi is needed.
