I am researching Bluetooth 5 for work and I cannot find anywhere the PHY layer of the different bluetooth modes (LE 1M (legacy Bluetooth 4), LE 2M (Double the Speed), LE Coded scheme 2 (2 x Range) & scheme 8 (4 x Range).
I know that LE 1M is IEEE 802.15.1.
This source (http://dev.ti.com/tirex/content/simplelink_cc2640r2_sdk_1_35_00_33/docs/ble5stack/ble_user_guide/html/ble-stack/phy-2mbps.html) says LE 2M is the same as LE 1M but with a different modulation. Would this make it still IEEE 802.15.1?
I haven't been able to find any sources that directly say if LE 2M, LE scheme 2 or scheme 8 are IEEE 802.15.1 or some other protocol. Any help is very appreciated, Thanks.
BLE is not IEEE 802.15.1 at all.
The PHY layers in BLE are specified in the Bluetooth Core specification under "Low Energy Controller volume Part A Physical Layer specification" which can be found at https://www.bluetooth.com/specifications/bluetooth-core-specification/.
