Android Question Use External Bluetooth GPS, Instead of Internal GPS?

[nemiroG1]

I am trying to find a way to use an external, bluetooth connected GPS in place of the internal one in my device, directly in my app. I have found a workaround to do this, by doing the following:

- Connect external GPS via Bluetooth settings (indicates Paired, but not Connected)
- Turn on "Allow Mock Locations" in Settings -> Developer Options
- Install the "Bluetooth GPS" app from the Play store, https://play.google.com/store/apps/details?id=googoo.android.btgps&hl=en

- Run the Bluetooth GPS service, with Enable Mock GPS Provider checked
- Enjoy the better GPS service


My app in B4A picks up the new GPS, no problem. Everything works. My question is, how does the service work? I would really love to be able to incorporate a service like that directly into my app, so I do not have to run a third part app. Can anyone help with this? Thanks!

You can use the serial library to connect to the device. You will need to parse the NMEA strings. It isn't too complicated.

Use AsyncStreamsText to handle the messages.
