Here a little more technical description:
I would like to know if it is possible to send data over bluetooth using
SPP stack in transparent mode (without any higher layer encapsulation from
Android).
When I send a data via Bluetooth using the following command in Android
device:
byte[] buffer ={0x33, 0x34, 0x42, 0x33, 0x34, 0x42, 0x34, 0x42, 0x33, 0x34,
0x42};
outStream.write(buffer);
I received the data (at the receiver side) as below:
+RADI=010,3334423334423442333442\r\n <----- in ASCII
I really would like to have the received data in pure binary form, without
the +RADI encapsulation etc.
Is that possible with Android?
