TS_RE or later after setting the device in Receive mode, any incoming packet will be detected and demodulated by the
transceiver.
4.2.6.3. Time to RSSI Evaluation
The first RSSI sample will be available TS_RSSI after the receiver is ready: equivalently TS_RE + TS_RSSI after the
receive mode instruction was issued.

TS_RSSI depends on the receiver bandwidth as well as the RssiSmoothing option that was selected. The formula used to
calculate TS_RSSI is provided in section 2.5.4.
