the name of the current waypoint. NONE means that there is no
waypoint set and so bearing and distance will remain at 0. To select
a waypoint, press BTN2 (middle) and wait for the blue text to turn
white. Then use BTN1 and BTN3 to select a waypoint. The waypoint
white. Then use BTN1 and BTN3 (swipe up/down on Bangle.js 2) to select a waypoint. The waypoint
choice is fixed by pressing BTN2 again. In the screen shot below a
waypoint giving the location of Stone Henge has been selected.
