Multiple SDR Devices on the same computer

GNU Radio

Dear all,

I’m using BladeRF hardware in my system. I want to use two devices on
the
same computer. The “osmocom Source” lets me choose several channels, I
actually need to use 2 channels. However, I don’t know how to set the
parameter “Device Arguments”. Could anyone help me with this?

Thank you so much,
Van-Ly

Use bladerf=0 in one instance of the osmocom Source and bladerf=1 in
another.

I’ve attached a text file with all the bladeRF arguments. A very useful
option for higher sample rates (above 5 Msps or so) is to increase the
USB buffering. I almost always use this argument list for my
applications.

bladerf=0,buffers=128,buflen=32768
