Kind of Softdevices

Question

Hello. 
 I have a question. 
 I use nRF52 and S132v2. I found some programs of nRF51, they use S110, S130. What change does it with difference of Softdevice's version number ? or where are written them? 
 Please tell me.

Hi 
All nRF52 devices use S132 softdevices for BLE. 
All nRF51 devices use S1X0 softdevices for BLE. (Where X can be '1', '2' or '3') 
 I am not sure if I understand correctly what difference you mean to ask, but each softdevice is different from other in the role it can take. 
 The softdevice revision is explained in the relevant specification. For example for S132 the latest one can be found here 
 
 Chapter 20 SoftDevice identification
and revision scheme 
 The identification scheme for
SoftDevices consists of the following
items: 
 
 
 For revisions of the
SoftDevice which are production
qualified, the version string consists
of major, minor, and revision numbers
only, as described in the table below. 
 
 
 For revisions of the SoftDevice
which are not production qualified, a
build number and a test qualification
level (alpha/beta) are appended to the
version string. 
 
 
 For example:
s110_nrf51_1.2.3-4.alpha, where major
= 1, minor = 2, revision = 3, build number = 4 and test qualification
level is alpha. Additional examples
are given in table Table 46:
