Description

Indicates the power transmission.

TxPower represents the power transmission of the beacon device transmitter. This value is also advertised for proximity purposes.

You can use this value as a calibration parameter:

Set TxPower as the expected Rssi value at 1m distance to the beacon. The reference unit is dBm.

This allows to retreive reliable values of distance to other BLE devices.
