Hi,

I have problems to get the python test scripts running.

My configuration is Ubuntu 13.10 with Kernel 3.8.0-27-generic. For the
installation of Bluez 5.7 I used the following commands:

./configure --prefix=/usr --mandir=/usr/share/man --sysconfdir=/etc
--localstatedir=/var -disable-systemd
make
make install

Then I changed the init.d script to the new bluetoothd, as pointed out
here: http://permalink.gmane.org/gmane.linux.bluez.kernel/35011

/etc/init.d/bluetooth stop
# do a backup of the original executable
mv /usr/sbin/bluetoothd  /usr/sbin/bluetoothd.orig
ln -s /usr/libexec/bluetooth/bluetoothd /usr/sbin/bluetoothd
/etc/init.d/bluetooth start

Everything worked fine and I can connect to the Bluetooth chip (Nordic
nrf51822) using the command:
sudo gatttool -b D1:83:15:3C:26:F0 -t random --interactive
I can read the descriptions, enable notifications as expected.

However, when I start the python heart rate example, I get the following error.

markus@markus-G33M-DS2R:~/ble-server/bluez-5.7/test$ sudo
./test-heartrate -b D1:83:15:3C:26:F0
Traceback (most recent call last):

dbus.exceptions.DBusException:
org.freedesktop.DBus.Error.UnknownMethod: Method "RegisterWatcher"
with signature "s" on interface "org.bluez.HeartRateManager1" doesn't
exist

Attached you'll find a dump (btmon -w btmon.dump) during the
./test-heartrate call as mentioned
here:http://article.gmane.org/gmane.linux.bluez.kernel/37419
I suspect that the dump is empty because of the small file size.

How can I get the script running?

Best Regards
 Markus
