Thanks Jan

I think perhaps the OP should read the FAQ of BLE 5 improvements

Hi JoonDong,

I believe Roger has answered your question, there is not much to say about SoftDevice:

It works pretty much the same, all "mechanisms" of interaction between HW, stack (SoftDeccice) and application looks the same.
As you see differences between BT4.2 and BT5 (LE part) are not so big, it is backward compatible and the same way as previous releases you don't need to support full feature set to be compliant with BT5. So if you are interested in particular feature then look it up in the infocenter.
If you already have application running on nRF52832 with SD S132 V2.x then migration to higher version of S132 or to nRF52840 and SD S140 V5 is easy.

If you mean anything specific by your question you need to tell us;) Cheers Jan

Do you mean what are the API differences between BLE 4.2 and BLE 5.0 ?

what I wonder is the method of softdevice between BLE 4.2 and 5.0..

Currently only the nRF52840 is fully BLE compliant, as the nRF52832 can't do the low data rate modes needed for long range, or the higher powered transmitter.

So. Looking at the product spec for the nRF5240 you will see that only the S140 SD is BLE 5.0
