BluetoothClient(C#) write delayed while reading from Android client

Question

I am trying to write the continuous data from bluetoothclient(C# NetworkStream) to Android client (BluetoothSocket). But I observed that C# write is getting blocked , while trying to read data from Android bluetooth socket.This block is not observed if I am not trying to read data from client. Tried using BufferedStream for writing , but still I see the same issue.

C# Bluetooth server Code :

NetworkStream _st = _clnt.GetStream();
while(true){
   _st.Write(_serData, 0, _serData.Length);
   // Required delay is given before writing next chunk
}

Android Bluetooth reader :

InputStream inputstream = btSocket.getInputStream()
while(true){
 int len = inputstream.read(buffer, offset, buffer.length);
 offset += len;
}

You should post some code if you want people to know what you're doing. — Peter Duniho, Oct 22 '14 at 18:39
Do you have any clue if this is blocked on android side or server side? I am immediately thinking this could be android permissions: http://developer.android.com/reference/android/Manifest.permission.html — Doff3n, Oct 29 '14 at 13:14
Even more code and specifications of the problem could help too — Doff3n, Oct 29 '14 at 13:15
Problem I am facing here is delay in writing data(C#) while reading data on other side. — MGK, Oct 30 '14 at 08:59
