Can someone confirm that TinyGPSPlus::distanceBetween() calculates the distance wrong?
To be sure that I’m not using it wrong I also checked the library’s example.
Distance to London shows me 7712km but it must be around 500km. Using an ordinary arduino with the Github library works as expected (520km). I tried with photon and electron…
Could there be a problem with the math functions? the code of the distanceBetween() looks correct to me…
