Unfortunately, there are no short cuts to learning... I suggest following the guidance given in Simplicity Studio when you plug in your Thunderboard 2 board... I believe they provide a quick start guide, which gives a great overview and provides links to explaining the Bluetooth stack etc. Understand this document and you are well on your way.

The only tip I can think of at this stage, is that as the values read from your analog pin can be larger than a byte, you will need to choose a characteristic type that matches your data type. In this case you could choose "short" or "integer" to handle the data transfer.

I had done same thing differently with RaspberryPi and a camera.

Welcome to element14. The PIR sensors I have used have digital output after detection with a reset after a period of time. Are you sure you need an analog read? It has been some time since I’ve used Simplicity Studio but there are a number of examples included, almost certainly digital and analog reads. The Silabs forums would be a good place to search and ask for help as well.
