How to use a smartphone gps as an external device?

Hi everybody,

first thread for me. I really hope is not already solved somewhere...but I searched the forum without success.

problem to solve:
I installed Open cpn on my notebook (Win10) and I can't get position datas from my phone (Samsung A8 android).
I tried many android apps to share the gps via bluethoot..... Opencpn see the virtual serial ports #6 and #7 but there's no communication (I tried all the baud rates).

Then I tried "GPS satellite" for win10 and it works but position doesn't come from an internal gps, it comes from networks around (it seems).

does anyone tried and/or solved this problem?

I'd really like to use the phone device as external gps so to use Opencpn on different boats.

thanks in advance

David

Re: How to use a smartphone gps as an external device?

Since no one answered, I'll give my $0.02, though it's not exactly the answer you're looking for. IDK how, or even IF, you can do what you're asking. But I do know you can simply buy a "puck" GPS for your computer for very cheap (Amazon_search puck gps). I used that for year before phones and tablets became cheap and reliable enough. Now I wouldn't consider using a computer on-board anymore with a good quality tablet costing $200-300. But the "puck" will allow you to do so.

David some years ago with my samsung s4 i solved it and wrote it up in the opencpn 4 books manual, under Supplimentary Software. Perhaps search on android gps. I listed several programs and showed how they work.

PS The phone got warm and used a fair amount of battery. You will want it plugged in for continuous use

"Bluetooth GPS" by Meow is your friend for sharing the GPS of the phone.
Alternativly try "GPS Tether".
