Sketch won't compile

[SL06]

HI, thanks for sharing.
I have those compilation issues, and was wondering if you can help. Thanks👍

By fixing issue 2, the sketch now compiled and work. The only problem is that Mag calibration is about 10 x longer than normal with my nrf52DK. In fact the 4 sec delay give about 40 sec delay. I had serial print comment to test the delay. So 15 sec testing give about 150 sec. I should probably test the program with my Uno.
