From 12c11ffb6eb1f68c9c83a6eee3f9d4011746b122 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Christian=20Str=C3=B8mme?= Date: Fri, 18 Nov 2016 16:44:36 +0100 Subject: Fix broken link in QMagnetometerReading The link, which describes how to calibrate the magnetometer sensor, is no longer available. As a replacement we now provide a generic approach for calibrating, and recommend that the user checks their device's documentation for more information.
