3.3 Function As soon as the power on, the T-368 Bluetooth GPS receiver begins the process of satellite acquisition, tracking, and Bluetooth radio connection. Under normal circumstances, it takes around 42 seconds (average) to achieve a position fix at the first time. After a position fix has been calculated, information about valid position, velocity, and time is transmitted over the output channel.
NMEA Protocol The T-368 interface protocol is based on the National Marine Electronics Association (NMEA) interface specification, namely, the NMEA 0183 standard. The T-368 is capable of supporting the following NMEA message formats specifically developed and defined by SiRF. NMEA Message Prefix...
