Ok, thanks. So that’s a powerful real-time travel tool. I don’t need the real-time functionality but I do need the data behind it.
A couple of years ago,I looked at RFO Basic! for Android on Google Play store. I know it had access to every bit of GPS info. I assume any language you want to use on the phone can access all the data.
Go to page 184 of the manual for an idea of what you can access: http://laughton.com/basic/programs/apks/De_Re_BASIC!-v0190.pdf
