Feasibility: SDK v11.0.0 S132, v2.0 on NRF52840

[Sami]

Hello,

Are there any hardware constraints or hard forks in putting an older version of an SDK, such as v11.0.0, on a much newer chip? 

I'd like to port SDKv11.0.0 to NRF52840. Are there glaring pros/cons? Thanks!

Hi

The nRF52840 does not support SDK v.11.0.0 nor the S132 v.2.0. If you check out the compatibility matrix you can see that the first SDK it supported was SDK v.12.2.0 with SoftDevice S132 v.3.0.0, and this was only applicable for the engineering A revision.

Thus, the later revisions are not tested with any SDKs older than v.15.0.0 and SoftDevice S140 v.6.0.0 and we can't guarantee any function what so ever. Furthermore, you will miss out on BLE 5.0 features such as long-range and extended advertising using this SDK, as well as support for some of the peripherals exclusive to the nRF52840, like the QSPI for instance. I definitely suggest using SDK v.15.0.0 and S140 v.6.0.0 or newer for an application for the nRF52840.

Best regards,

Simon

Thank you for the confirmation. I'll double check the compatibility matrix.
