Click the Setting function in green rectangle described above, one would be able to
configure NTRIP/Bluetooth LE/Map settings and will see window below.
NTRIP setting
Requires the host address, port number, authentication (user, password)
information for accessing the caster/private base.
To provide the nearest RTK correction data (i.e. shortest baseline), the caster
may require the GGA for the position of the RTK device. In this case, turn on
this function and the APP will send the location of the iPad to the caster
continuously and automatically.
To keep reasonable baseline, iPad should
not be far from the GR-9029.
Bluetooth setting
Name gives the Bluetooth name of the discovered GR-9029. Please click the
SCAN function to discover all Bluetooth devices in the neighborhood. The
default name of GR-
9029 is started with “NPASP-“.
In case of multiple GR-9029s are active. One can distinguish one from
another by this name. This name is labelled on the disk body of GR-9029.
Map setting
Allows one to manage path display, measure distance, and
use one’s own
map for display. For the details, please see next section.
