Thank you. I had suspected that step wise migration might be difficult, so I appreciate you confirming that.

Hi,

There has been a lot of changes since SDK v6 up to the now current nRF5 SDK v15. You are most likely best off by starting a new project in SDK 15 and porting/adding one feature at a time from the old project. Nine stepwise migrations from one version to the next is not an option.

Better write a new firmware completely than trying to migrate. There is a library that could help writing BLE firmware easier.

Hello,

How did this approach at migrating go?

I am about to start something similar(code from another developer as well) and would appreciate any insight you gained during the process.

Our current firmware was developed using SDK v6 on a nRF51 based device and supporting another device with nRF52 hw seems like it will take substantial development time.

There is a migration guide that comes with the documentations of each SDK. You can find it in there.

Is there any migration guide between the different SDK versions? What kind of role does the softdevice play in this? The code I am dealing with (that I inherited from another developer) seems extremely married with the library, i.e. there is no encapsulation whatsoever, the code is littered with references to SDK functions and definitions.

Since you already based on the hrs example. I would recommend using the hrs example from SDK14 and bring in your code. There are too much changes between the 2 hrs examples. Not just that you are also changing to a different processor. The intermediary moves are a waste of time.

Hi,

You are correct that there are a few changes from SDK 12 to SDK 14, although the biggest leap in that strategy would be from SDK 8 to SDK 12.

In our experience, the easiest way to migrate several major releases is often to start out with a fresh project based on a suited example from the latest SDK and then gradually copy functionality over from the old project to the new one. That way you migrate smaller portions of the original project at a time, and if done in a thought-through order you should be able to test each new addition on the way.

Regarding the diff from SDK 12 to SDK 14 for main.c of the ble_app_hrs_c example, I find approx. 250 lines changed, of which many changes are actually in comments or whitespace. That being said, I see quite a few API changes as well, both for SDK libraries and for new version of SoftDevice.
