All content below this line refers to {{#multireplace:System.Beacon.Components.TCustomBeaconDevice.TxPower|H21=!|H25=%|H28=(|H29=)|H2A=*|H2B=+|H2F=/|H3C=<|H3D==|H3E=>|H5B=[|H5D=]|H5E=^|H7C=|}}. 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.
