Do note that the FWID is not located at the same address for all SoftDevices and versions. To find the correct address for a particular SoftDevice, look up SD_FWID_OFFSET in the SoftDevice header files. Or alternatively, see this answer for both FWIDs and locations for most SoftDevices.

Hello,

According to this post, the list of what firmware ID maps to which SoftDevice version is not public. Here are some SoftDevice versions with the corresponding FWID:

SoftDevice          | FWID
--------------------|-------
S110 v5.0.0         | 0x002C
S110 v5.2.1         | 0x0043
S110 v7.0.0         | 0x004F
S110 v7.1.0         | 0x005A
S110 v8.0.0         | 0x0064
----------------------------
S120 v2.0.0         | 0x0060
----------------------------
S130 v1.0.0         | 0x0067
S130 0.9alpha       | 0x005E
S130 v2.0.0-7.alpha | 0x0078
----------------------------
S310 v2.0.0         | 0x005D
----------------------------
S132 v1.0.0-3.alpha | 0x006D

The FWID value is available at address 0x300C. You can use the following command to read it. Here is an example:

$ nrfjprog --memrd 0x300C
0x0000300C: FFFF0067

Hi Craig

Yes, chapter 6 in the S110 softdevice specification 2.0 should answer both of your questions.

As of now, there is no table available that maps FWID with softdevice versions

Update 17.4.2015 The identification ID (FWID) for the softdevice is placed at address 0x300C in the softdevice hex file.

When you have flashed the softdevice to the nRF51 you can read the FWID with

nrfjprog --memrd 0x300C

The FWID numbers for S110 are:

S110 8.0.0: 0x64
S110 7.1.0: 0x5A
S110 7.0.0: 0x4F

Update 22.6.2016 More softdevice IDs are here
