What exactly is txPower for Bluetooth LE and how is it used?
<p>I am trying to understand what exactly txPower is and how to use it, since I am planning to develop and Android app that uses Beacons. </p>

<p>I have seen 2 definitions online:</p>

<p>1.The transmitted power of the beacon.</p>

<p>2.The received power 1 meter away from the beacon.</p>

<p>How are these two definitions related?
Also, when transmitting a Beacon signal from a device using an app such as QuickBeacon, how do I determine what to set the power (txPower) to?</p>
