How to achieve 2Mbps with Bluetooth 4.2 on nRF 51 series.

Question

I read the specifications on nRF51 series and the spec say that Bluetooth 4.2 with 2Mbps. However, standard Bluetooth 4.2 only support maximum 1Mbps bitrate. 
 First, I wonder about that how to achieve 2Mbps with Bluetooth 4.2 and the chipset can support 2Mbps mode actually. 
 If so, could nRF52 support 2Mbps mode actually?

Hi, 
 
 nRF51 series has a 2 Mbps mode (called 2Mbps NRF mode) that is not compatible with the 2Mbps BLE mode introduced in Bluetooth 5. You may use it as you like for non-BLE purposes, e.g. Enhanced Shockburst . 
 
 nRF52 series supports both 2Mbps NRF mode and 2Mbps BLE mode, and thus has support for 2Mbps in the respective Softdevice versions. 
 
 Best regards, 
 Andreas
