How to read chip ID, chip Revision & BLE softDevice version number (nrf5340 project)

Hi Gerard,

in nRF5-SDK, the SoftDevice, is both Bluetooth Host and Bluetooth Controller combined.In nRF Connect SDK, we use the Zephyr Bluetooth Host, and the SoftDevice Controller. If you run a bluetooth sample in NCS, it always prints this SoftDevice revsion thing at the start of the log.

So you can use sdc_build_revision_get() to get the build revision.

Hope this helps.

Hi Priyanka,

Thanks for your answer. I guess I am now REALLY confused! I have been developing on the nrf5340 for more than one year so I thought I knew it well by now! :)

You say: "The 5340 does not have a SoftDevice on it".
So guess I am using the wrong terminology!? When I use the word "SoftDevice" I am referring to the BLE Stack (aka netapp) running in the network core of the nrf5340 (after one has built a system with SDK v2.3.0 - for example). I thought this is called the "SoftDevice"!!? I am surprised to hear that you don't use that term and that you say it doesn't run on the nrf5340!?

Anyway, I need to know how to read the version of the BLE Stack or "network app" (which I thought consists mainly of the so-called SoftDevice) from my "cpuapp" code running on the 2nd core?

This seems a pretty straightforward question to me - please let me know what YOU call the "BLE Stack" (software) that runs on the 5340 (if it is NOT called the "SoftDevice"). As I said - I am mow REALLY confused!

Thanks!

Gerard

Hi Gerard,

The 5340 does not have a SoftDevice on it, and the chip ID etc you can find in the FICR.

Please also take a look at the Compatibility matrix.

Best Regards,

Priyanka
