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,
sudo hciconfig hci0 leadv
However, when I try to run a BLe GATT server using,
bluetoothd -d -n
I get the following output:

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).
The BlueZ 5.27 stack was built from the source code as follows:
./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
No errors were reported during the build and installation.
Why is the Sap driver failing to initialize?
Thanks for any help you can provide.
After a reinstallation, it seems to have corrected itself. For the benefit of others, I'm listing how I installed, and got the example GATT server running:
My environment:
Installed packages:
Downloaded BlueZ 5.31 from here: https://www.kernel.org/pub/linux/bluetooth/bluez-5.31.tar.xz
Installation of updated kernel:
A reboot is necessary. I'm using Vagrant and lost shared folder access. If this happens to you, wait for vagrant to report the error and go into the VM anyway (vagrant ssh). In the VM, issue this command to fix the shared folder problem:
I would reboot again (probably not necessary), to check that the shared folder is active again.
Once back in the VM, continue the installation of BlueZ 5.31:
Installation completed. Check it as follows:
You should get the follow response (or something similar):
Bring up the Bluetooth adapter, start advertising, start example GATT server (heart rate service) with verbose on:
Go to another device (I've used an iPod and another PC running BlueZ but having problems with Android devices) and connect to the service. Here is how I did it on another PC running BlueZ:
You can issue other commands to read and write to the GATT server.
I love this forum finding many answers here. I hope this small contribution helps at least one other frustrated developer out there.
