Thanks a lot for the link. I have now managed to
download the application. I will interface this
program with GT31 GPS from Locosys.
Cheers.

Sure, make sure you don't "desynch" it though, these dataloggers probably react differently than a "simple" GPS receiver.

I think I know what you may mean. You believe
there might be a problem if i simply run the
application as it is (without setting/changing
parameters, etc), watching only signal level,
response and debug views. Will GT31 come out
of synch even then?
Thanks.

No as long as you don't send any commands you should be ok. The older versions of SiRFdemo also forced you to switch to a SiRF binary and that could create problems as the baudrate was changed in the process, now you can get detailed info too in NMEA mode.

Ok, thanks for the quick reply,that's great.
GT31 works at constant baud rate of 38400.
I wished it could change down to 4800, since
I want to use it with MS Autoroute 2007 as a real
time GPS receiver, but this application is only
compatible with GPS at 4800 baud.
Anyway, that's another story.
Cheers.

does anybody know how to connect to a garmin c550 using this software and usb or bluetooth? My sirf firmware needs a downgrade since webupdater did me in. I tried installing sirfdemo & the uart/usb software

I get error code 10 just trying to start the driver.

No chance, not sure what your problem is, but you should check out the topics in the Garmin section for tips on how to fix it.

Did you try every possible baudrate at this point?

i try 2400 that work the nmea protocol in the other baudrate i can't view the nmea string

When i try to change protocol i obtain only this

in error view

warning setcommstate()failed in CSerialComm::open
warning SetComm(0x1000)() failed
warning SetupComm()failed

comm:CE_FRAME
comm:CE_BREAK
....


i have an other question, the 1 PPS output it's enable when there is the fix or must be enable by sirfdemo ? because i have wired the probe of the oscilloscope but there isn't the 1pps signal !

sirf mode: PSRF100,0,38400,8,1,0
nmea mode: A0A20018 81020101 00010101 05010101 00010001 00010001 00019600 012BB0B3

Nokia LD-4W (GSWLT3.2.5NOK_3.3.01.01-CL31B1.00):

"Action -> Switch to SiRF Protocol" works fine (bt link goes down, after reconnect it is running in sirf-mode).

"Action -> Switch to NMEA Protocol" does NOT work (bt/gps go out of sync, need to power cycle), but manual NMEA switch works with 0 baud.

"Action -> Transmit Serial Message...": a0 a2 00 18 81 02 01 01 00 00 01 01 05 01 01 01 00 00 00 01 00 01 00 01 00 01 00 00 00 93 b0 b3

Hi Everyone, and especially Carl@sirf if you're still there:
I'd need to run SirfDemoPPC on a windows CE 6.0. I could hardly download the software from the internet, as sirf.com is not available anymore. I installed it, and it doesn't seem compatible with my OS. Is there a way to make it work ?
If someone has experience about this...

Hi,

SiRFdemoPPC was intended to run with Windows Mobile and generally the "stripped down" Win_CE devices have too many software modules missing.

It depends what you want to do, but have you seen/tried "SirfTech" which manages most of the SiRF functions and has wider platform support:

Cheers, Alan.

Thanks Alan,
SirfTech works fine. I also managed to run SiRFDemo 3.87 from my laptop through ActiveSync. For this I use :
- Franson GPSGate 2.6.0.367 on the laptop (input = ActiveSync)
- Franson GPSGate 2.6 build 347 BETA for Windows CE .NET on the device (output = activesync)
