Can two applications use one bladerf board ?

[blrfuser]

I have a single bladeRF board.

I am sucessfully running a single application like this:

airprobe_rtlsdr.py -f 1960.8M

and everything works fine.

However, I would like to monitor *two* GSM base stations at the same time with just the single bladeRF by running two difference 'airprobe_rtlsdr.py' commands, each on a different frequency. Is this possible ? Can you timeshare the bladerf device, perhaps configuring timeslices to switch back and forth on ?

Thanks.

No, this doesn't work especially with USB.

What are the two frequencies you want to see? How are you configuring your device?

The two freqs would be something like 1960.8mhz and 850mhz ...

I was hoping I could hop frequencies every second or so ... spending one whole second on each frequency.

Maybe I could just do that myself with a script ... run airprobe for one second, capturing the output, and then kill that process and run it again with a different frequency ... I could just timeshare the device myself.

So am I correct that the gnu radio framework locks the device and only lets one process access the bladeRF at a time ? When I start a second 'airprobe' process simultaneously, it does not work because it can't access the bladeRF instance... ?

Any program that opens the bladeRF locks it - that is my experience.
I would suggest investing into GNURadio. You could make a flow graph to suite your needs.
But it is not going to be easy...so if time = money then maybe best option is to just buy another bladeRF

Out of curiousity, is it the same situation with a RTL-SDR device ? If I started a second userland program (like airprobe) that listens on the device, it will be locked out by the first instance of the program ?
