B4J Question GPS access from B4J

[laithzib]

Trying to create an application in B4J that needs to use GPS location speed etc. What library does B4J need to use for this to work. I also cant seem to find any examples in B4J only B4A example seem to exist. Does anyone have any examples of code for GPS access under B4J.

Many Thanks in advance

I can´t remember seeing a GPS-Library for B4J.
Usually a WindowsPC does not have any GPS.
Mobile devices do have. But here you can not run any B4J App.

USB GPS "mouse" should register as a serial port eg COM8: and generally default to emitting data in NMEA format (human readable) at 1 Hz.

I saw this post before some years... but never tested.... and I am thinking... why not working... as emexes said: is just NMEA...

I am developing this program but I am having trouble reading the serial port. I can not say if my device or a programming error. my receiver transmits the data for a few seconds and then stops transmitting. if someone that has a serial or USB GPS and could test, would be very grateful. My...

so, i dug out a usb gps device i had for windows and which i haven't
fired up in years, and certainly not on my current device.
plugged it in, and it automatically found and installed a driver and reported
it was active on com10.
i searched a little and found this link for a java library for gps:
https://sourceforge.net/projects/javagps/

it claims it can access gps devices from within any java application.
library, source, dox all included in download. warning: an example
"run.bat" will fail. it seems to assume you're running a mapping app.
other similar libraries i saw also assume you're running some kind of
mapping app (which may or may not be true in your case).

back in the day, microsoft had a mapping app into which you could
plug an exterior gps device. that's how i used mine.

Assuming that the GPS device is connected as a serial device then you can use jSerial to read the NMEA sentences. You will need to parse them. It shouldn't be too complicated.
