1. Introduction
1.1 Overview
The ProGin T-368
solution GPS receiver with Bluetooth, UART interface and built-in rechargeable battery for high
sensitivity to tracking signal.
The T-368 receiver incorporates a wireless Bluetooth radio module, a high sensitivity, high performance
SiRF Star chipset, and a rechargeable battery in a compact design. The SiRF Star chipset is with extremely high sensitivity for GPS signal acquisition and tracking. This Bluetooth GPS receiver allows
you to receive GPS data on mobile hand-held devices. By sending the GPS data wirelessly, you may
place this receiver on a position with best signal reception without the constraint of annoying wires. The
receiver is equipped with a portable, rechargeable, with removable battery, just like a mobile phone. The
only requirement is your corresponding hand-held device is also with the Bluetooth connection capability.
The receiver is very suitable for broad applications such as vehicle navigation, mapping, surveying,
security, agriculture, etc. Only a clear view of sky and a battery power are necessary to the unit. With its
low power consumption, the receiver tracks up to 20 satellites at a time while offering fast time-to-first-
fix, re-acquires satellite signals less than 1 second (average) and updates position data every second.

3. Operation
3.1 Getting Start
Step 1: Battery Installation
(a) Slide the power switch to “OFF” position. (b) Press the “PUSH” button then slide the bottom cover off. (c) Insert the Li-ion battery into the compartment. Note the orientation of the battery. (d) Slide the bottom cover back to locked condition.
Step 2: Charge Please charge the battery to full capacity when first time to use. Connect the attached adaptor cord to the
mini USB jack, as shown in the following figure.
The battery indication is with dual-color LEDs. The green LED will be on until charge completes.
The LED indication for the battery status is described in the following.
Battery low ----------------------------------------------------------------- Red LED flashing Battery in charging -------------------------------------------------------- Green LED steady on Battery charging suspended (protection when charge timer over or battery overheat) ----------------- Green LED flashing Charge completes or battery in normal capacity ---------------------- both LEDs off
T-368 User’s Guide v1.0

Step 3: GPS acquisition Turn the power switch “on.” The slide switch is on the broadside of the body. Once the power is turned
on, both the Bluetooth and GPS indication LEDs start to flash.
Take the Bluetooth GPS to places with clear view of the sky. The Red LED indicates the status. (a) LED steady on when power is connected and for the initial acquisition process;
(b) LED flashes at 1 second on and 1 second off when the receiver outputs position fix data.
Step 4: Wireless Link Turn on the host device, a PDA or a NB with Bluetooth function. Then execute Bluetooth manager
program to perform “search” and “pair” procedures. The default PIN code is “0000” for host devices to access this BT GPS unit (in paired mode).
The Blue LED indicates following Bluetooth radio status. (a) LED flashes at 3 seconds interval for standby mode;
(b) LED flashes at 0.2 second interval for pairable mode; (c) LED flashes at 1 second interval if there is an active RF link.
3.2 GPS Viewer for Testing
Install a GPS Viewer program to host device. You may check the status of the GPS receiver whenever you like to. Following are standard buttons and operation steps. (a) Execute the Viewer program. Press the “Com Port:” button to set “Com Port” for this data link and
the “Baudrate” to any one of 2400, 4800, 9600, 19200, 38400…
(b) Click “Start” to receive data. Usually a window shows the NMEA format data stream while another
window shows tracked satellites signal quality.
(c) Once the link is successful, click “Stop” button to stop the program. However, you may click, for
example, the “Cold Start” button to perform “cold start” testing.

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. The T-368 Bluetooth GPS
receiver utilizes initial data, such as last stored position, date, time and satellite orbital data, to achieve
maximum acquisition performance. If significant inaccuracy exists in the initial data or the orbital data is
obsolete, it may take more time to achieve a navigation solution.
3.4 Navigation
After the acquisition process is complete, the T-368 Bluetooth GPS receiver sends valid navigation
information over output channels. These data include:
1) Latitude/longitude/altitude
2) Velocity
3) Date/time
4) Error estimates
5) Satellite and receiver status
4. Warranty
The GPS smart receiver is warranted to be free from defects in material and functions for one year from the date of purchase. Any failure of this product within this period under normal conditions will be replaced at no charge to the customers.

Appendix: Software Specifications
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 Format Direction
$GPGGA Time, position and fix type data. Out
$GPGLL Latitude, longitude, time of position fix and status. Out
$GPGSA GNSS DOP and active satellites Out
$GPGSV Satellites in view. Out
$GPMSS
$GPRMC Recommended minimum specific GNSS data. Out
$GPVTG Speed and course over ground. Out
$GPZDA Date and time. Out
General NMEA Format
Radio beacon signal-to-noise ratio, signal strength,
frequency, etc.
Out
The general NMEA format consists of an ASCII string commencing with a ‘$’ character and
terminating with a <CR><LF> sequence. NMEA standard messages commence with ‘GP’ then a
3-letter message identifier. The message header is followed by a comma delimited list of fields
optionally terminated with a checksum consisting of an asterix ‘*’ and a 2 digit hex value representing
the checksum. There is no comma preceding the checksum field. When present, the checksum is
calculated as a bitwise exclusive of the characters between the ‘$’ and ‘*’. As an ASCII
representation, the number of digits in each number will vary depending on the number and precision,
hence the record length will vary. Certain fields may be omitted if they are not used, in which case
the field position is reserved using commas to ensure correct interpretation of subsequent fields.
