Hi,
I am facing kind of the same problem with ScenePlayer on Android.

For some time ago, I wanted to make another phone application 
communicate with ScenePlayer. My idea was to inject the data into 
ScenePlayer via localhost using networking utilities of Pd. For this 
purpose, I recompiled ScenePlayer including externals from the mrpeach 
library, then I tried several configurations in order to test the 
different network protocols between the phone and my computer.

My conclusion is that there is only one way to have a working 
bidirectional data exchange: [tcpclient] on the phone and [tcpserver] on 
the computer. In all the other configurations (simple 
[netsend]/[netreceive] or [tcpsend]/[tcpreceive] for example) it was 
possible to send data from phone to computer but not from computer to 
phone. When I tried to invert the working configuration (putting a 
[tcpserver] on the phone), the following happened: the [tcpclient] on 
the computer seemed to be connected (outlet 2 was set to 1) but could 
not send (nor receive) any data to the phone.

Unfortunately, this does not enable me to have a direct connection 
between an external mobile application and ScenePlayer as I had hoped. I 
gave up momentarily with the idea of using network utilities, but I 
think that this is a question of interest for people working with Pd on 
Android: is there a reason for incoming TCP and UDP streams to be blocked?

Cheers
