Example for proximity sensing

[Anonymous]

Is there an example and good tutorial about proximity detection.

My application is intend have BLE peripheral (device) and central (smartphone).  When phone is within 2ft of the device, the device does X.  Assuming the device is always scanning, or waken by user through some UI.

What is the best sample code to start with?

How do I measure distance using RSSI? 

Can I change device Tx power? How?

This is a good thread to start with: Re: How to find RSSI from WICED SMART?

In addition, we provide the proximity_client and proximity applications within the SDK within the \apps directory.

There is also a Broadcom 'Find Me' application on Google Play.

Regarding changing power settings, this is probably the best thread: Re: How to find RSSI from WICED SMART? , but there are several others as well.
