Hello bluez,
as the subject notes, I'm trying to receive non-connectable undirected
advertisements from a bluetooth low energy device, namely TI's
SensorTag. Their SDK contains a sample app named SimpleBLEBroadcaster,
that, supposedly, sends those advertisements including some data. There
is an overview of TI's understanding of this mechanism for download at
http://e2e.ti.com/support/low_power_rf/m/videos__files/653593/download.aspx
Is it possible to receive/display the *data* (up to 31 bytes, I believe)
that can be contained in those advertisements using bluez? I currently
don't care whether it's a commandline tool, C-based API, python, DBUS,
anything.
When I start SimpleBLEBroadcaster, btmon alone doesn't show anything,
but "hcitool lescan" says.
LE Scan ...
90:59:AF:0B:8A:7D (unknown)
The complete output of a btmon during lescan is attached below.
https://github.com/bmpm/bcast-observer-demos and a script named
"test-bluetooth-observer" made me believe that there should be an
org.bluez.Observer interface for this, which I couldn't find using
qdbusviewer.
I asked on #bluez before, but it seems noone knew.
Thanks!
