GPS - Windows 10

[barnakiel]

Why not pick it up from a wifi router?

All my onboard toys do: 1 tablet, 1 smartphone (both Android, different versions), 3 Windows machines (XP, 10H, 10P). No hiccups.

I use a cheap nmea wifi router I built onboard for 10 bucks.

Cheers,

Would you please share what you used to build the system on your boat.
Thanks

You are a lazy bum with no Google access, eh? ;-)

But off course. No problem. The components listed below as per your wish.

Nmea wifi/ethernet router for the poor:

- a s/h wifi router, (2-5 EUR in any Cash Converter)
- a 232/usb converter cable (prolific or ftdi) (8-10 EUR any Dick Smith)

The router runs OpenWRT software and kplex does the serial to wifi conversion.

The USB/232 cable is not required, if you like to solder.

If you do not, the router must have a USB slot.

Cheers,

Dear Gerard

I have seen this post and I have tried

Geolocation tcp, https://bitbucket.org/petrsimon/geolocationtcp, together with the GNSS datainterface

as mentioned in my post without success.

Don't know how he got it to work. I can't.

I don't believe you've fully described your process step by step. If you have one software program using the gps, it captures the gps. You must release it so opencpn can use it!

We know opencpn works when the nmea serial signals are available and the correct com port is properly configured by the user. It is all under your control!

Thanks your reply.
Have now got it working with GeolocationTCP-r9 and Network settings in
OpenCPN accordingly. Wifi still on!
Still unable to get it working with serial Com3 settings.
Have Com3 working as you can see in enclosed screenshot (GnssDataInterface).Have closed GnssDataInterface and rebooted to be shure nothing is occupying Com3. Start OpenCPN with NEMEA Debug window. No data. Tried diffrent baud rate. Still no luck

[rgleason]

This is helping us understand. The screenshots and description. Use complete, clear sentences please.

[rgleason]

Can you set the baud rate to 4800 and try that? That is the normal baud rate for gps.

Also good you closed the gnss program and check it is free.

Have you tried looking in your windows system devices list to find the com port, but when gnss program is on and when it is off?

Send a screenshot of both those conditions please if possible.

After we know those conditions we might have a suggestion.

[fyrekrig]

Thanks for helping out. Sorry if my previous post was not clear enough.

Can you set the baud rate to 4800 and try that? That is the normal baud rate for gps

Tried that. Do not work. Using com0com Com 3 baud rate is emulated
Can not set to fixed value. See enclosed screenshot.

Have you tried looking in your windows system devices list to find the com port, but when gnss program is on and when it is off?

No changes in Com3 properties if GNSS is on or off. See enclosed screenshot

[rgleason]

I am puzzled by this.

[rgleason]

There is no change in the com3 port when the gnss program is on or off. Puzzles me.

This gnss program you are using comes from what manufacturer? Please post the website if it is available.

It does not look at all like the one we reference in the User Manual.

On this page
https://opencpn.org/wiki/dokuwiki/do...rted:gps_setup

to this link

http:// opencpn.org/wiki/dokuwiki/doku.php?id=opencpn:supplementary_software:win8_gn ss_sensor

It appears that the gps device is in serial mode and out puting nmea gps sentence data on serial port com3.

In opencpn, connections window, can you please uncheck checksum and see if the opencpn data window is streaming any data.
Try it several ways please.

Also if the darn gps really is going at 57,600 baud (I don't believe this for a minute) then I don't want to give you the impression that opencpn connections will not handle this speed, it will. I just doubt that the gps is really properly operating at 56,700 baud. I've not seen one work at that rate. Can you slow it down to 4800 baud throught settings and then put it back into serial mode? Read the gps manuals and software instructions!

DO you have the correct driver for your Broadcom?

[rgleason]

Fyreking,
Exactly which broadcom sensor is it? Model numbers and website link please. Also as weavis suggests have you updated the driver for the gps?
Additionally, is it an integrated with your computer? Also how old is your computer?

Does the manufacturer provide software to control the settings for the sensor?

Have you tried uninstalling and reinstalling the driver?

[fyrekrig]

This gnss program you are using comes from what manufacturer? Please post the website if it is available.

I am not sure what programs you are referring to.

If it is GNNSS sensor it is Broadcom 4752

If it is GnssDataInterface here is the link

In opencpn, connections window, can you please uncheck checksum and see if the opencpn data window is streaming any data.
Try it several ways please.

Do you mean NMEA Debug window? If it is another data window, can't find any?

No data. See screenshot

Also if the darn gps really is going at 57,600 baud

GPSGate says

The baudrate of the virtual ports uses the baudrate your application uses automatically.
If you connect at 4800 baud to the virtual port, you get the data at 4800 baud.

DO you have the correct driver for your Broadcom?

Have looked for more recent drivers without luck
but this one works with other programs i.e Google Maps, Bing Maps etc

See screenshots

Exactly which broadcom sensor is it? Model numbers

See screenshot

Additionally, is it an integrated with your computer?

The computer is an ASUS T200TA and the sensor is integrated. About 2 years old.

Does the manufacturer provide software to control the settings for the sensor?

As far as I know there is no utilty to change any settings on the sensor

Have you tried uninstalling and reinstalling the driver?

Don't think unistalling and installing the driver will change anything as it is working properly. Did it anyway. No change

As the Braodcom sensor with present driver is receiving GPS data the issue has to be with OpenCPN not wanting to work with virtual com ports.

[rgleason]

Fyreking, we have many examples of opencpn working with virtual ports for GPS, so the problem definitely is not opencpn.

Your documentation is good, do you have patience to try some more?

It is completely within the user control, and since the sensor is only 2 years old we should be able to get it to work, but there is another example of an older broadcom that just would not work with win10 and the answer was to get a puck gps.

If you have the time, would you please try the gnns program, that I linked to in the User Manual, without using your gnnsdatainterface program (cant be active) or gpsgate.
1. Reboot with the little stub gnns program I linked to earlier in the thread. Follow the instuctions.
2. Then find which COM port is being used in windows by going to config -system-devices and look under com ports. Hopefully you will see the sensor and com port number.
3. The go to opencpn options connections uncheck all connections, then add a new serial connection, usually when you go to the comm port selection the correct one will automatically appear, if there is a serial nema data stream available.

Try this several times in different ways, rebooting, to make sure you've got it correct. It should start working

I am describing from memory here, so please review the manual gps section and the short tutorial for starting up with opencpn by Terry yachtvalhalla.

Please post as you have been, so we can help further.

Thanks
