Introduction
MobileMapper CX is equipped with built-in Bluetooth technol-
ogy that allows short-range connections to other Bluetooth-en-
abled devices such as cellular phones, personal digital
assistants (PDA), desktop or notebook computers.
Bluetooth offers fast, reliable, and secure wireless communi-
cation.
Host and Inquiring Devices
In any communication between two Bluetooth-enabled devic-
es, one of them is the
inquiring device and the other the host
device :
• The inquiring device is the one that detects and uses one
of the local services of the other device.
• Reciprocally, the host device is the one that is discovera-
ble and that makes its local services available for the
inquiring device.
Here are two typical examples in which MobileMapper CX is
successively the inquiring device and the host device:
• When you operate MobileMapper CX in NTRIP or Direct IP
DGPS mode, the cell phone used is the host device and
MobileMapper CX is the inquiring device. The local service
used in the cell phone is the
Dial-Up Networking service .
• When you output GPS data via the auxiliary port,
MobileMapper CX is the host device and the external
device receiving the data via Bluetooth is the inquiring
device. The local service used in MobileMapper CX is the
Serial Port Service.
