Question about Bluetooth Long Range with nRF52840

Hello everyone,

right now I have two BMD-340 Evaluation Kits which used nRF52840 module and I want to evaluate Bluetooth Long Range and Data Rate of this module. I used s140 Softdevice in this case. When I used this s140, that means all of the examples which I used in nRF_SDK using Bluetooth 5 with Long Range? 

And if it's possible, an explanation about Softdevice is very helpful for me. I have read about it but it is outdated since 30-11-2018.

Best regards,
