Why is discovering peers for Android Wi-Fi Direct so unreliable?

Question

I am experimenting with Android\'s Wi-Fi Direct (or P2P if you prefer). I thought it was working very nicely between my two phones, but I realized I am encountering issues w

Answer 1

I had a really big problem with establishing connection between devices:

• first device turns on peer discovery
• second device turns on peer discovery
• one device tries to establish connection with the second one
• sometimes it works, sometimes not (I would say 50/50)

I guess the issue was the group owner negotiation (I've tried change groupOwnerIntent param also to force who should be group owner, but it didn't helped).

So, what did I do?

I change flow to:

• one device creates group (mManager.createGroup(...)), so this device is always a group owner
• second devices connects with group owner
• whooala, now is very rare to stuck on invited state.
