pattern. These 80 bits are not FEC encoded as usual but they are sent directly to the radio channel. It is followed by a header block ("FEC Block 1") which is always transmitted in S=8 mode. The header block only contains the destination address ("Access
Address" / 32 bit) and an encoding flag ("Coding Indicator" / 2 Bit). The Coding Indicator defines the Pattern Mapping used for the following payload block ("FEC Block 2") where S=2 is possible.

transmission power—is achieved at the expense of a lower data being at an eighth with 125 kbit. The old transmission packet format, as it continues to be used in the 1M PHY and 2M PHY modes, has been named "Uncoded" in
Bluetooth 5. The intermediate "LE Coded" S=2 mode allows for a 500 kbit data rate in the payload which is both beneficial for shorter latencies as well lower power consumption as the burst time itself is shorter.

While the discovery latencies of BLE can be approximated by models for purely periodic interval-based protocols, the random delay added to each advertising interval and the three-channel discovery can cause deviations from these predictions, or potentially lead to unbounded latencies for certain parametrizations.

Bluetooth 5 has introduced two new modes with lower data rate. The symbol rate of the new "Coded PHY" is the same as the Base Rate 1M PHY but in mode S=2 there are two symbols transmitted per data bit. In mode S=2 only a simple
