* @brief (int8_t) Received Signal Strength Indicator (RSSI)
*
* The RSSI is an indicator for the received field strength in wireless
* channels. It is often represented as the ratio of received power to
* a given unit, for example milliwatts. With a device-dependent scaling
* factor, the RSSI value can be expressed as power level in the unit
* dBm or ASU (Arbitrary Strength Unit).
