Introducing the new Azimut mechanics induced a side effect... My manual calibration procedure no longer worked for this axis.

This is due to the fact that:

• the azimut motion is no longer linear and follows complex motion equations
• the azimut bottom plate should be pointing to the south

So I decided to implement a new procedure of calibration into the Android application. Don't panic it is even simpler than before!

• launch the App
• put the phone on the ground parallel to the bottom plate and align the North (this calibrates the bottom plate)
• put the phone on the panel (bluetooth enabled)
• press the ESP32 reset button
• the ESP32 automatically connects to the phone and gets the time and the location (as previously)
• now push the "find Sun" button, this will send the current Elevation and Azimut angles to the ESP32 
• quit the App to resume normal tracking mode.

Here is what you should see on the screen

And the panel will rotate to the right position, pointing to the sun ! 

This should be done only once after powering the ESP32. 

Once done this calibration will be kept into the memory of the ESP32 (even during night).
