[android-developers] Re: Bluetooth Peer to Peer network in Android..

Hi,

I have had 3 and 4 ptp bt connections on real android devices ( all
different ) & once 5, but I found getting reliable connections beyond
3 is usually quite difficult.

Configuration was 1 server & multiple clients, I think you may do
better if you daisy chain connections.
