Re: [Bluez-devel] AVDTP socket?

Marcel,

Shouldn't this work to send the header in a separate write() and have a 
struct for it?

I thought everything ended up being little-endian on the wire, but

     buf[2] = seq_num >> 8;
     buf[3] = seq_num & 0xff;

looks big endian to me (00 then 01 for 0x0001). When my code writes to 
sequence_number, it comes out little endian (01 then 00 for 0x0001).

Brad

    while(!terminate) {
-    memset(buf, 0, 12);
-    buf[0] = 0x80;
-    buf[2] = seq_num >> 8;
-    buf[3] = seq_num & 0xff;
-    buf[12] = 0xff;
-    buf[13] = 0xff;
-    size = read(fd, buf + 14, mtu - 14);
+    memset(&packet_header, 0, sizeof(packet_header));
+    packet_header.cc = 8;
+    packet_header.sequence_number = htobs(seq_num);
+    packet_header.csrc[0] = htobl(0xffff0000);
+
+    //    dump_packet(&packet_header, sizeof(packet_header)); exit(0);
+
+    size = read(fd, buf, mtu - sizeof(packet_header));
      seq_num++;
      if(size <= 0) {
        terminate = 1;
      } else {
-      // framing, fragmenting, a2dp headers: avdtp p.45 and a2dp spec p.23
-      write(streamfd, buf, size + 14);
+      // avdtp p.45
+      write(streamfd, &packet_header, sizeof(packet_header));
+      // what about framing, fragmenting, a2dp headers (a2dp spec p.23)
+      write(streamfd, buf, size);
      }
    }
    close(fd);
