community.psion.com/cfs-file.ashx/__key/CommunityServer.Discussions.Components
21.1.3 External GPS
You can use external GPS units with Psion computers. You can use any device that communicates with the
Psion computer through a serial port, a card slot, or over Bluetooth. In these cases, you must also provide
software that configures the GPS, communicates with the GPS and processes the data from the GPS.
21.2 Mobile Devices SDK Support for GPS
The Mobile Devices SDK provides APIs that support the built-in GPS units.
The Mobile Devices SDK does not get GPS data, nor does it interpret it.
GpsHelperI Class
This class supports the GPS hardware as follows:
• Control and configure the GPS receiver.
• Power-on and power-off the GPS receiver.
• Enable and disable GPS reception.
• Select the GPS profile.
• Select the suspend mode for the GPS.
The options available through the Mobile Devices SDK, on a specific computer, are the same as those avail-
able through the GUI applet on the computer. See the user manual for your computer for descriptions of
the options.
