Re: [Discuss-gnuradio] Airspy: multiple boards available with GNU Radio?

Quick look.

libairpsy provides an API to open based on serial number.  Near as I can tell, gr-osmosdr hasn't caught up with the newer airspy API.

Mr. Tom Rondeau,

Thank you for the info.  Yes, I thought of controlling the airspy by the source-block parameters.  But, reading this URL.

http://sdr.osmocom.org/trac/wiki/GrOsmoSDR

Airspy explanation is like this.

AirSpy? Source
  airspy     Use this argument without a value
  bias=1|0   Enable or disable DC bias at the antenna input

So there seems no parameter for choosing 1 device from 2 (or more).
How can we control?   I want to know this point...

Regards,

Mamoru Yamamoto

 

Any osmosdr people here that can help Mamoru? Sylvain, do you know anything about this?

    Dear Experts,

    We recently found Airspy as a very interesting SDR board for our
    purposes.  Our project, some may already know, is to develop 2-channel
    (or more-channel) coherent receiver for satellite beacon.  We so far are
    successful at 2-ch (150/400MHz) RX with USRP-1.  We now search for new
    SDR boards for future expansion.

    My question is simple.  We bought 2 units of Airspy.  Now we can run
    Airspy on Ubuntu, but do not know how to run 2 units from GNU Radio.  Is
    it possible?  Airspy software with Ubuntu consists of several programs.
      For example "airspy_info" can find 2 units on the PC and show info.
    "airspy_rx" can run by selecting one of the 2 units.  Running 2
    "airspy_rx" programs from Ubuntu seems OK.  However, now we do not know
    whether it is possible to control 2 Airspy from GNU Radio python code or
    not.  We hope to know current situation and (hopefully) near-future
    possibilities.

    Sincerely,


You can use the gr-osmosdr's source block to address multiple devices:
