The S112 soft device and the nRF52810 datasheet both advertise support for BLE LESC, so I think it's reasonable to assume that it should work. However, none of the example sdk_config.h for the S112 even contain BLE_LESC_ENABLED, let alone with any value. (I solved this by adding the attribute, but if I edit with the CMSIS tool, I'm afraid it will revert my change.)
Additionally, the ble_lesc.c file in the SDK cannot compile with the S112 headers, as the S112 does not support the GAP Central role but the ble_lesc.c file looks for defines based on this. Applying this tiny patch (based on styles used elsewhere in the BLE portion of the SDK) seems to make things compile correctly, but I'd love to know if there's another way I should be doing this.
