nRF 52, S132: Security Mode 1, Level 4?

[Henry]

Hi,

Can someone tell wether Security Mode 1, Level 4 is available on the nRF52832 and SoftDevice S132?

In one PDF I found only Level 1,2 & 3 but in the S132 API reference I also see Level 4.

So is Mode 1, Level 4 really available?

Thanks, Henry

Yes, it is available. To enable it you can set SEC_PARAM_LESC to 1 (using the peer manager). However the security mode is not enforced so the peer has to support it as well. You can take a look at the softdevice migration document (nRF5_SDK_11.0.0_89a8197\components\softdevice\s132\doc\s13x_nrf5x_2.0.0_migration-document.pdf) for more details.
