title: BlueZ error: Sap driver initialization failed
body: <p>I've exhausted my search on trying to resolve this problem. I can't seem to get the example GATT server running in BlueZ 5.27. I'm running a Linux VM (kernel = 3.16) connected to a Broadcom BCM20702A0 Bluetooth 4.0 USB dongle. I can run hciconfig, hcitool, and gatttool with the associated commands and these work properly. I start advertising using,</p>
  
  <pre><code>sudo hciconfig hci0 leadv
  </code></pre>
  
  <p>However, when I try to run a BLe GATT server using, </p>
  
  <pre><code>bluetoothd -d -n
  </code></pre>
  
  <p>I get the following output:</p>

  <p>The Sap driver fails to initialize and I'm guessing that this causes the hci0 adapter to fail to load the connection parameters (see output).</p>
  
  <p>The BlueZ 5.27 stack was built from the source code as follows:</p>
  
  <pre><code>./configure CFLAGS="$CFLAGS -Wno-sign-compare -Wno-format-security" --prefix=/usr --mandir=/usr/share/man --sysconfdir=/etc --localstatedir=/var --disable-systemd --enable-experimental --enable-maintainer-mode
  make
  sudo make install
  </code></pre>
  
  <p>No errors were reported during the build and installation.</p>
  
  <p>Why is the Sap driver failing to initialize?</p>
  
  <p>Thanks for any help you can provide.</p>
