English Bluetooth Manager Module This chapter gives general information on MobileMapper CX's Bluetooth Manager module. For detailed information on how you can establish a GPRS connection via Bluetooth Manager, please refer to Step-by-Step Procedure for Establishing a GPRS Connection Via Bluetooth on page 18. Introduction MobileMapper CX is equipped with built-in Bluetooth technology that allows short-range connections to other Bluetooth-enabled devices such as cellular phones, personal digital assistants (PDA), desktop or notebook computers. Bluetooth offers fast, reliable, and secure wireless communication. Host and Inquiring Devices In any communication between two Bluetooth-enabled devices, 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. 50
