Difference between nrf proprietary and BLE phy modes?

[sandeepvl]

Hi,

I am trying to understand the different PHY modes available in nrf52840. What are the differences between nRF 1Mbit and 2Mbit proprietary modes when compared to BLE 1Mbit and 2Mbit modes? 

Thanks

The only difference is the modulation index, or the deviation. BLE 1 Mbs uses 250 kHz deviation while nRF mode is 160 kHz. And 500 kHz / 250  kHz for 2 Mbps.

Thank you for the clarification.
