enum type

struct scoped enum wrapped by the class

Enumerator
NONE	No phy selected. Note This value can be used to indicate the absence of phy
LE_1M	1Mbit/s LE. Note This physical transport was available since Bluetooth 4.0
LE_2M	2Mbit/s LE. Modulation is similar to LE_1M but differs in rate. Therefore range performances are in the same ballpark as LE_1M while the increased rate minimize time spent to transfer or receive a packet which leads to a better power consumption and/or faster transfer. Note This transport has been introduced with the Bluetooth 5. When operating at 2Mbit/s range is not exactly identical to the range at 1Mbit/s due to a loss in sensitivity.
LE_CODED	LE Coded PHY. This transport reuse the 1Mbit/s channel with different coding schemes. Either two (S=2) or eight (S=8) symbols can be used to represent a bit while the 1Mbit/s transport use 1 symbol to code 1 bit of data. Here is the data rate of the two coding schemes: S=2: 500kbit/s S=8: 125kbit/s The goal of the coded PHY is to increase the range of BLE devices. Of course given it takes more time to transfer data, transmission and reception last longer which leads to an increase in power consumption. Note This transport has been introduced with the Bluetooth 5.
