How does one create a udp network port?

The software that uses one creates it, I think. The client can only use whatever the server delivers. But I am not 100% sure this is the only option. Others may chime in.

Not saying I know, but IMHO tablet/PC GPS chips first go to WIFI location not true sat GPS. I went back to my external GPS dongle to get a consistent reading.

Please do some searching. Both of these questions (UDP and GPS) have been covered in user manual and multiple posts here. Limited bandwidth prevents me from searching for you.

Go into location services, see what you find.

On our tablet one can elect wifi location / 3G location / GPS location or any combo of the above.

Available location method is then elected by the software.

This would be interesting (and a bit odd) if marine navigation software were using wifi or 3/4G location as default, without clearly telling the user this is the case.

Unfortunately, i-Services (like AIS via wifi/3G) much as they are useful, added a layer of misunderstanding as to what is available, when, and what the consequences are.

OK, I have some bandwidth to answer your question. I already answered it earlier in this same thread:

It was also answered in the instruction manual that was installed with OpenCPN 4.0. You can find the web based version here. Scroll down to item #2:

I think I see why I'm having trouble understanding this udp concept. I don't have a router. I'm trying to share the data coming from an external bluetooth gps sensor between two instances of Opencpn running on my Lenovo MIIX. The sensor is a Dual model XGPS150A universal GPS receiver.

I've got the geolocationtcp loaded but get nothing from the MIIX's internal GPS sensor. Device manager says it's working but geolocationtcp only sees the 30 sec transmission that comes from the internet. If I turn off the internet geolocationtcp reports status as "no data". I've even loaded the latest GPS drivers from lenovo.

There is also at least one other paid app that addresses this issue, but I have not used it because the free one worked for me.

(Oops, I read your note very sloppily. I dind't see that you already have Geolocation TCP installed.)

It sounds like the Encore is getting its location from a WiFi map, not from the GPS. Windows8 has that capability. I don't know the Encore, but the GPS should be putting out a 1 Hz NMEA feed.

Try downloading the free Sensor Metro app from the Microsoft store. That should tell you whether your GPS has a fix, or whether it's stuck on "Initializing" status.

Hi RythmDoctor
I know is an old thread, but the issue persist. Recently bought a Teclast X98 Air 3g tablet. China job but nice tablet nonetheless. Having trouble getting OCPN to pick up GNSS input. Running Geolocation TCP, and it's ok, updating every 30 sec or so. Have configured the Net port on OCPN according to instructions in the online manual, but still nothing happens (picture attached). In the tablet, Windows reports Broadcom GNSS 4752 installed. Is there any other config item in OCPN that I need to change? Help much appreciated!

Is it correct that you are running 3.2.0?
The first you should try is to update to 4.0.0

At lot of stuff has been improved for the comunication part.
And the documentation relates to it.

Windows may be showing the Broadcom sensor to be installed and working, but with reporting 85m accuracy, windows is getting location from wifi or 3g and not the GNSS sensor. I have the same issue with my iRulu Windows 8.1 (now win10) tablet. I now use a usb gps for OpenCPN

Thanks Leo
I thought so too initially! However, WiFi connection is off and the tablet does not have a SIM. So it's not polling any data from the Intenet, nor from the GSM network. Where then does it get the location data from, if not GNSS??

The plot thickens...

Just for information purposes, MS surface pro 3 tablet does not use usb for power. Has its own unique plug, but there is a 12vdc cig outlet cable available on amazon which works well, leaving the one usb 3.0 free.
