S110 and secure connection

Not really, but we have a many examples that support pairing. I believe they should work with "rolling" address as well.

Do you have sample code with S110 v8 or S130 v2 that use rolling address with pairing?

The address will change every time you call sd_ble_gap_adv_start() independent of interval.

Not exactly on each. To check I use hcitool with and without --duplicate. I found the address change each time I call sd_ble_gap_adv_start. Maybe it's the problem? I start and stop advertising because it's a remote with CR2032 battery and I doesn't want to use a lot of power. I also change the interval between advertising frames for the same reason (depending if the remote move or not).

Currently all remote sold have S110 V7.1.0 and if it's possible we prefer to keep this version to avoid OTA of softdevice and the application. Maybe we can switch to S110 V8 if needed but for S130 we need to check if we have enough memory (S130 is bigger I suppose) and if it's possible to perform OTA on existing device to switch from S110 to S130.

On each advertising frame? Are you sure? How are you checking? I need to look into which SDK version that supports bonding with IRK. Are you tied to S110 v7.x? Do you have a good reason for not using S110 v8 or S130?
