Connecting multiple devices in a Wifi Direct group

I have 3 devices (I call them device A,B, and C) and I want to connect them in a group.
I can do one-to-one connection now and it works fine.

However, while I am trying to connect the third device, the connection between the other two devices fails.
For example, first I connect A and B. After negotiation, A becomes the group owner. Now everything is alright. Then I try to connect A and C. The accept message prompts successfully on C, but "most of the time" the connection fail, and A and B also disconnect.

Why I say "most of the time" is because it really works, although the probability is very low (< 10%).

Anyone happen to know why this happen?

Once A is a group owner, it can't initiate any more connections. The connection has to be initiated by the device outside the group.

When you try to connect using wifi-direct, you're setting up a wifi network with the group owner as the access point. If you try to connect again, you're going to be trying to set up a new wifi network, which will force you to leave the old one.

Short version: Each device can only connect once.
