Another option could be to advertise with A, B and C in the whitelist.

If A connects first, you stop advertising.

If B connects first you continue to advertise with A in whitelist, and then if A connects you disconnect B and stop advertising.

If C connects first you continue to advertise, if B then connects you disconnect C and continue to advertise with A in the whitelist and so on..., and if A connects you disconnect C and stop advertising.

trying to whitelist all single hosts will be too slow for me. But now I know that it can't be done in "normal" way. Thanks!

It is not possible to block B and C if A is available. Either the devices are in the whitelist or not.

The only way I can think of is using a timer. When the device is powered up you whitelist with A for x ms, then after x ms you put in B and then after x ms you put in C.

Yes, this would make the connection to C slower if only C is available, but what is too slow I can't say for your application. You can tune it by selecting how long you want to wait before you put more devices into the whitelist.

Will this work for you?
