Official bladeRF forum

Hey,
I've been working on BladeRF and I'm able to generate signals from it using gnuradio flowgraph (osmocom sink). But I'm not been able to receive signals using osmocom source. The osmocom_fft example was not working either. Can anyone help me with this. I just had a wild idea that would there be need of using external power (adapter) to receive signals properly.

Thanks

Can you be a little more specific on what is not happening?

Is you run with osmocom_fft, what do you see? Do you see anything? Are there errors on the console?

No I didn't got any errors. The output I'm getting is in this video. https://docs.google.com/file/d/0B5ZnEve ... t0dGM/edit. I am trying to receive a sine signal transferred from my USRP. The other way i.e., transmitting it from BladeRf and receiving it from USRP works fine.
When I run osmocom_fft in XY mode the output is like this. https://docs.google.com/file/d/0B5ZnEve ... ZiTFU/edit.

Thanks

On the bladeRF receive side, could you try bringing that VGA1 gain down -- 33 dB is quite a lot. I too, have seen some instability when the gains are set way too high -- I believe this is currently being investigated. Try just a few dB, rather than 33.
