Relationship between SDK and sotfDeivce

[takashina hiroki]

I have a question about the relationship between SDK and sotfDeivce.

I want to use nRF SDK v15.3.0.
I know that the document has the following description.

    This version of the SDK supports the following SoftDevices:
    S132 SoftDevice v6.1.1 (API documentation)

Is it possible to use an older version of softDevice with this version of SDK?
For example, "S132 SoftDevice v5.0.0"

Thank you you in advance.

Why would you want to do that?

As the name suggests, a change in the  "Major" version number - eg, 5.x.x to 6.x.x - usually indicates a Major change; so they are unlikely to be compatible.

Thank you for answer.

I need to use S132 SoftDevice v5.0.0 due to hardware limitations.
The hardware is not approved for technical compliance unless it is S132 SoftDevice v5.0.0.

I want to use the sample project "ble_app_multirole_lesc".
nRF SDK v14.2.0 (S132 SoftDevice v5.0.0) does not operate as intended.
nRF SDK v15.3.0 (S132 SoftDevice v6.1.1) operates normally.

Therefore, I want to move with the combination of "S132 SoftDevice v5.0.0" and "nRF SDK v15.3.0".

I understood that the combination of "S132 SoftDevice v5.0.0" and "nRF SDK v15.3.0" is impossible.
Thank you for answer.
