RE: Converting firmware from S140 to S132

Hi Austin,

I think it can be a good idea to do a quick side-by-side comparison of a pca10040 (nRF52 DK board with nRF52832 as the target IC) and pca10056 (nRF52840DK board with nRF52840 as the target IC) configuration for one of the existing SDK examples to get an overview of what the differences are. There aren't that many.

Here's for instance a diff of the ble_app_hrs example from SDK 17.0.2

I am hoping that I can just swap out the s140 files with the s132 files, change the keys to match and also change the command I use on the nrf util line when I am generating packets and I will be good to go.[/quote]

It depends on the project, but it's often pretty straight forward to convert a project from one 52 variant to another. I guess the trick is to work directly with the xml encoded .emProject file and not do everything through the GUI (takes time to navigate through the setting menus).

[quote user=""]First off, am I correct in assuming that I will have to convert to the s132 soft device on the NRF528232 chip?[/quote]

Yes, s140 has not been qualified for this chip as you can see here: SDKs and SoftDevices.

The nRF52 Series comparison table can also be used as a quick lookup to compare the difference in HW features between the 52832 and 52840.

Best regards,
