Compass gadget use and calibration
Immediately after installing the BlessTags application, you will notice that the compass application does not work.
This is a perfect example to highlight the need for calibration of the magnetic sensor – placed on CC2650STK or CC2541DK SensorTags. In the following, a sensor calibration process will be presented.
In a future post, I will present the mathematical basis of the magnetic sensor calibration and the software implementation mode.
