| LE_1M |
1Mbit/s LE.
|
| 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.
|
| 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:
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.
