5.5.4 Indoor Surveying
The hand-held probe provides the option for using GPS data from an external source using a Bluetooth
link. This can be useful for indoor surveys. One possible external source is an Android smart phone
running an app such as ‘Bluetooth GPS Output’, ‘GPS Share BT’ or ‘GPS NMEA Bluetooth Transmitter’.
It is then possible to use a dead-reckoning location app such as ‘SmartNavi’ for indoor positioning although
our experience is that currently this app is not sufficiently stable to be used for reliable surveying.
To pair the hand-held probe with an external GPS source:
- enable Bluetooth on the Android phone
- open the hand-held probe, move the Bluetooth Mode slide switch to ‘SLAVE’ as shown below
- force the phone to scan for new Bluetooth devices
- select the device with the correct name, e.g. ‘Aries_HH_6001’
- pair with the probe using code ‘1234’
- enable GPS on the phone
- change the slide switch in the hand-held probe back to ‘MASTER’ as shown below
- start the appropriate GPS sharing app
- enable the ‘Make Discoverable’ option in the app
- within a few seconds the phone should auto-connect to the probe
- once the phone has good GPS coordinates, confirm the probe ‘Ext GPS’ LED is lit
