BlueTexGPS Mobitex Integration guide v.2.6
4
PRODUCT PRINCIPLE
The main aim of the BlueTexGPS is to provide personal navigation and a back office
positioning solution combined in one unit. This is achieved by integrating a GPS
receiver, a Bluetooth chip and a Mobitex radio modem in the BlueTexGPS.
MOBITEX MESSAGING OPTIONS
The BlueTexGPS has the ability to save POSPAC18 messages internally and send
many of them together. This means that the mobitex traffic load decreases as only
one big message is sent instead of many small ones. The traffic load decreases
because only one message head is sent. The actual amount of position data is of
course the same. Up to 28 POSPAC18 messages can be packed in one mobitex
transmission. Up to 1900 POSPAC18 messages can be stored locally. If the
BlueTexGPS has lost contact with the mobitex network, all generated messages are
stored locally. When network contact is acquired again, all messages are sent in the
same order as they were generated.
CONFIGURATION OPTIONS
The sending and generation of the POSPAC18 messages are configurable through a
protocol. The parameters are set over the serial Bluetooth interface, RS232 interface
or by a message over the mobitex network.
The configurable parameters are:
•
Receiver MANID for the POSPAC18 messages.
•
POSPAC18 generation and sending time interval.
•
Individual payload associated with the F1 to F6 function buttons on the
BlueTexGPS keyboard.
•
Additional function associated with any function button.
•
Unit mode.
o
BlueTex mode: When checked direct access to the mobitex modem is.
Not checked (normal mode) provides GPS-data for personal navigation.
o

packed together in one transmission. When checked up to 28
messages are packed together. When not checked every message is
sent individually.
•
Power up and down method
•
External I/O in the DSUB9 connector
FUNCTION BUTTONS
The buttons F1 to F6 can be configured to contain a payload. That payload will be
attached to the pospac18 message when the button is pressed. If a button is
pressed it will be indicated by the led at over the button.
There are two types of button types. Momentan and sticky. The momentan button is
when a status is momentan and sticky is when a status stays active until the button is
pressed again. There can only be one sticky button active at the time. Sticky and
momental buttons is configurable.
