Hello,

I'm still having problems with getting information from beacons using
the DBus API. Using the DBus API is generally working well. But if
there are devices that are advertising in 'broadcast' mode then I
can't seem to get the service data being broadcast by the beacon.

Following on from discussions had before
(http://thread.gmane.org/gmane.linux.bluez.kernel/65201/focus=65263)
I've experimented with Bluez 5.36 and 5.37.
I've compiled the above versions with --enable-experimental  and
--enable-maintainer-mode and have the bluetoothd running with -E

Linux kernel:
$ uname -a
Linux raspberrypi 4.1.13+ #826 PREEMPT Fri Nov 13 20:13:22 GMT 2015
armv6l GNU/Linux

I have various beacons around and also have got another Raspberry Pi
broadcasting an Eddystone URL using the Bluez DBus API. All of these
beacons can be seen fine by various apps on my phone.
The code for the advertiser using DBus API can be found at:
https://github.com/ukBaz/python-bluezero/blob/master/examples/eddystone-url-beacon.py
which can be run with:
python eddystone-url-beacon.py http://www.bluez.org/

To do the scanning for the beacons I'm using either bluetoothctl or
using the test/test-discovery script in the Bluez download.

Any help or suggestions as to what I'm doing wrong would be appreciated.

Thanks in advance,
Barry
