[Tinyos-help] MTS420 GPS receiver

[prajakta choudhari]

Dear all:

i am building an application using mts420 gps receiver that keeps on
receiving gps packets till it gets a valid gps packet. As soon as the
valid packet is received, the application shud glow red light and stop
forever.

It seems that the gps does not work without a timer.
So i have used 2 timers. On the event of the first timer fired the gps
is powered .
On the event of the second timer fired the  gps txrxswitch is enabled.
Then the application starts receiving gps packets. On receiving a
valid gps packet i have called

call GpsCmd.TxRxSwitch(0);
call GpsCmd.PowerSwitch(0);


to stop gps receiver.
But still after the receiving a valid gps packet it,doesn't stop. It
starts the ONE_SHOT timers again..and the cycle repeats.
I am attaching my code..
It would be really gr8 if somebody throws light on this issue.
Thank You.
Prajakta
