Calling GR Functions in a Sync Block

2020-12-06 Thread Adam Gorski
Community,

Is there any way to call GR functions from within a sync block? I am attempting 
to put code from a deprecated hierarchical block (dbpsk_demod) into a custom 
sync block that carries out dbpsk demodulation from within a sync block. I am 
using the sync block because I need to demodulation to occur only for specific 
packets that are tagged by a preceding block.

Any calls to gr.() result in an error, ex. 'module' object has no attribute 
'agc2_cc'.

As an alternative I figured perhaps I can add the tag selection code from the 
sync block into the hierarchical block, however I am not aware how to combine 
the work function of the sync block with the hierarchical block code.

Any help is appreciated, thank you!

from gnuradio import analog
agc = analog.agc2_cc()

Library libbladeRF for bladeRF 2.0 micro xA4

2020-12-06 Thread Alvaro Pendas Recondo
Hello,

I am considering buying an SDR model bladeRF 2.0 micro xA4 that is supposed
to be compatible with GNU Radio through the library libbladeRF. Does anyone
have previous experience handling this model with GNU Radio or other models
by Nuand? I have experience with USRP and UHD, witch integration with GNU
Radio is great, but I do not if that would be the case with libbladeRF. Any
input would be greatly appreciated.

Thank you in advance!

Alvaro

I built the bladerf stuff on a raspberry pi a couple of years back to go along 
with OpenBTS/gnuradio.  It was fairly straight forward

I used gnuradio with a bladeRF 2.0 micro xA9 this summer with a raspberry
pi running ubuntu. Once I got everything figured out it worked great. You
just have to make sure you have all of the necessary dependencies
installed. You should also use Ubuntu 20.04. I got compilation errors for
Raspbian and older Ubuntu versions because they lacked the necessary
dependencies.
