Andrej,
( this thread for background: SeeYou fails to see GPS data
http://localhost/naviter_forum/discus/forum/messages/1031/1335.html?1106615029 )
I believe that I have discovered the cause of our problem with the NODATA messages.
I upgraded to Win CE 2003 the 11 of January.
Since that time I have, until today, not been able to connect to the iPAQ3975 com 6 4800 baud.
Here is what the PPC does:
After starting mCU an initial NODATA msg apperars followed by BAD... .
Shortly after mCU locks on to the GPS (com6 4800 n81).
Again after a short time,30-45 seconds, NODATA appears and the cycle repeats untill shutdown.
Now here is the curious part: using a GARMIN etrx GPS on com1 mCU has NO trouble seeing the Com1 and working properly.
This problem apperars to me to be directly related to the upgrade PPC ce 2003 and the Com 6 port.
To eliminate a hardware problem I used my friends EMTAC GPSjac (same as mine) to determine if my iPAQ had a connection
problem. This test elimininated that possibility.
I am unable to reload PPC CE 2003 or I wouldn't trouble you with this.
I know your team will be able to address the fix as you have many others in the past.
Good luck.
Hope to hear from you soonest.
Rod
