What GPS devices does ArcGIS Mobile work with?
The ArcGIS Mobile application and SDK runtime use the same API to communicate with GPS receivers. They work directly with GPS devices that support the National Marine and Electronics Association (NMEA) protocol, which is a one-way protocol that ArcGIS Mobile consumes, enabling it to locate itself for use in navigating maps or creating new GIS features. Given that ArcGIS Mobile supports NMEA, you can be confident that it is designed to be used with a range of GPS devices (including internal GPS chipsets embedded in devices, external Bluetooth GPS, and external USB GPS). NMEA does not enable ArcGIS Mobile to control the settings of a GPS that supports it. To do this, a third-party tool must be used that uses a two-way protocol, such as Trimble or SiRF.
