A customer using iSXBlue II GNSS with iCMTGIS PRO on an iPad mini 2 sent us a few question:
1) He wondered how to tell if the iPAD running iCMTGIS PRO is operating with the external SX Blue II.
With the iPad paired over Bluetooth with the iSXBlue II GNSS, tap on the GPS icon and select “Turn GPS on”. A GPS marker should appear and the app should issue a navigation beep once every second. This indicates that the app is receiving the GPS position data from the iPad, to which the iSXBlue II is sending the GPS signals.
Now, tap the GPS icon and select “Turn GPS off”. Select Main Menu – Setup then select GPS. In the GPS Setup screen, select “Enable the external GPS” then select “GNSS RECEIVER”. Set the threshold values as desired then tap on OK.
When you tap the GPS icon and select “Turn external GPS on”, a GPS status line should appear at the top of the screen, showing the number of satellites used, the PDOP value, etc. This indicates that the app is obtaining the GPS data directly from the external GPS/GNSS and not just getting the GPS position from the Apple CoreLocation.
2) With respect to the iSXBlue RTN NTRIP app, he asked, “I have this app and presume both your app and this one need to be open and running at the same time?”
RTK work means you are making use of the correction data sent out by a RTK network provider. Therefore, both the iSXBlue RTN NTRIP app and iCMTGIS PRO need to be open and running at the same time.
