I have two SDRplays, but I do not see a method in the API for addressing more than one unit. Is this possible?

Thanks

dtaviation, you don't say what software you are using - assume SDRuno. Please look at this for an obvious solution. I have not tried it, but I suspect SDR-Radio will support multiple radios. Enjoy, John.

Question for Moderator - How many of my posts must be vetted before they are posted?

I'm writing software using the API. RTL SDR dongles have an index in order to select which of multiple dongles are plugged in. I do not find such a thing in the SDRplay API.

dtaviation, I opened SDR Console (SDR-Radio) then Select Radio - Definitions and see that AirSpy has a serial number but my SDRPlay does not. I don't know what happens if I plug in two SDRPlay radios but you might try it. It looks like the developers need to answer your questions. Have you tried the Contact page? Sorry I could not help. Enjoy, John.

Hi
That is a good question.
With 2 identical RTLSDR dongles I had problems too.
But sometimes it is simpler to use 2 or more devices instead of a complex mixing/switching antenna setup.
As a bonus you can run them at the same time .

dtaviation, while I was doing some testing on VirtualBox (a virtual machine application), I see this in their USB manager when my SDRPlay is plugged.

Maybe there is some useful information here.
Enjoy, John.

I also would like to see an answer to this question from the SDRPlay development team.

I also have a need for support of 2 receivers. What say, SDRPlay development team ?

Multiple RSP devices work (I regularly test 3 at the same time just fine on Windows) - you access them in the order that they are connected to the bus. Just be careful of bandwidth and make sure you don't connect more than 2 on a given USB hub. You can use something like USBView to make sure.

Best regards,

With some research, I found that the RSP has firmware (MSI2500). It is loaded by the driver at connect time. I have also seen articles describing how to change the serial number of the RTL dongle so they can be distinguished in SW. I would think if the SDRPlay team could give the user access to the firmware (update) there might be a path for a similar process. Enjoy, John.
