[Tinyos-help] Creating specific module for gps

[gwenhael.goavec]

Hi,
I use TinyOS 2.x.
I have an custom board with an msp430.

The communication between PC and Board is made with Uart1(UTDXD1) only for transmission board --> computer.
The URXD1 is used for reading data from the gps ( gps --> board).
Actually I send paquet board => computer and i read data from gps by
shorcutting the message stack (using UartStream) only on 4800bauds.

Many problem exist :
Communication between board and computer need to be made on 9600 bauds.
Communication between gps and board need to be made on 4800 bauds.

I wish to create an specific driver, with specific configuration (4800baud, read only,...) for the gps.
And an other configuration for sending(9600bauds, write only,...) for communication with computer
Actually, I have finding nothing informations.
Thank you very much

Gwenhaël
