Problem of multi-link using the relay unit

[KIYOMI]

I would like to carry out communication with a plurality of peripheral using a central multi-link function.

When performing the communication via the relay unit, the communication of the second and subsequent, there are cases where advertising is not accepted.

At that time, Central SCAN is operating normally, it is possible communication with another peripheral.

Why, in the second and subsequent communication, Will advertising can not be accepted?

Thanks for the quick answer. I am sorry that the description was not sufficient. My problem is not that the two peripherals can not connect. In the following 3rd step, Central can not respond to advertising from the relay. Central can respond the advertising from the peripheral. Do you know the reason why the Central can not respond?

1st step：first communication 　　　　peripheral -> relay -> central -> relay -> peripheral 2nd step:all disconnect 3rd step:second communication relay -> central : NG

Thanks for the quick answer. Unstable communication is not in either of the above conditions.After all has been disconnect, via a peripheral device again relay, it may not be able to connect to the central.

Here describes "unstable communication".

When there are two communication paths as described previously (see below);

Peripherals’ communication paths:

1. A peripheral can directly communicate with the central.
2. A peripheral can communicate with the central via a relay station.

Communication with path 1 is fine, but communication with path 2 has a problem. The peripheral can establish communication with a relay device, then it may or may not establish the communication with the central (unstable communication). We tested the environment only with path 2, then the communication was established fine. The question is if there is any known issue to have two types of paths we currently have?
