Hi all,
Dimitri merged the patch set to gr-osmosdr master yesterday.
Beware of a little catch, there are some examples floating on the net with
"hackrf=1" as the device argument. Device index numbers are 0-based (like
with rtlsdr and other drivers), so you'll have to use hackrf=0 if you
only have a single device attached, hackrf=1 would be the second device.
Before this patch the hackrf gr-osmosdr driver did not care about the
parameter at all.
Device selection by serial number tail ("hackrf=beeff00d") requires
updated hackrf firmware. The firmware changes have been in the hackrf git
master, but there's no official firmware binary published yet.

Hi,
I have a little pull request for gr-osmosdr, to enable multiple devices
support for hackrf. This allows doing things like full duplex using two
boards in a single graph.
You can specify either hackrf=0 and hackrf=1 to select by a device index, or
the serial number (or an unique suffix of a serial number), hackrf=f00d and
hackrf=1234abba. hackrf_info lists multiple devices and their serial numbers.
Apps like gqrx seem to magically work, too, and allow device selection.
The hackrf project just merged the pull request for libhackrf & tools 3 days
ago, and it's already available in macports at least.
The gr-osmosdr patches here do work against old libhackrf as before, it
detects the presence of the new hackrf_device_list API and enables multiple
device support only if it is available.
What is the preferred patch format, I have the changes available as a feature
branch in github?
