Softdevice Naming rules

[Himanshu]

I am newbie here. I was reading ‘Introduction to Nordic nRF5 SDK and Softdevice' dated 15 Jan 20. The softdevice naming rule establishes Sxyz

wherein z – denotes the SoC family; 0 indicates nRF51 series. 2 or 3 indicated nRF52 Series.

One of the examples given is S112: - z in this case is 2 and hence nRF52 series

In second rule, the last two digits of the softdevice number refer to chip model. The example used is S140; digits 40 means softdevice can only run on nRF52840.

I am not sure about usage of S140. As per information, 40 means softdevice can only run on nRF52840 i.e. a chip of nRF52 series. But with pattern of Sxyz; z here is 0. A 0 value of z indicates nRF51 series.

I find the above information contradictory unless I have interpreted it wrong. Can someone please answer?

Hi,

There is not a strict naming rule. We have several SD versions that supports different chips. Please look at the compatibility matrix to see what softdevice's are supported on the chip you are using. i.e. SDKs and SoftDevices
