Hi Marius,

There are something I want to clarify here.

If we are talking about the Initiator role, where the device scan for advertising packet from a whitelist or from one single device (with our S120 there is only the latter option), then we are not be able to receive other adverting packet from other device outside of the list.

But if you are talking about Central role where the device is in a connection with a peripheral, then it's possible (by spec and with the S120) to do Scanner role concurrently. This means between the connection events we can do scanning and can receive advertising packet from other device. Of course only after the earlier connection event ends and before the next connection event starts. The S120 can handle 8 connections with peripherals and do scanning in between.

Just found the part in the Core Spec which would rule my request out: Corespec 4.0, Volume 6, Part B, 4.3.4 - This basically demands the Link layer to ignore packets that are not whitelisted for a connection.
