I recently graduated with my degree in Computer Engineering, and the GNU
Radio project is by far the most complex thing I've desired to work on. I'm
looking for tips on how to get started learning GNU Radio from the ground
up, build custom modules, and help develop the source.
For example, an
I'm looking for some tips on how to improve file transfer using two USRP's.
I understand the method I'm using might be fairly crude, but I'm just
starting out.
Problem is I'm dropping a lot of data out of the file (receiving missing
parts of a string and such). This gets really bad when one of
I'm looking for tips on how to deal with the USRP TX/RX leakage. I'm
transmitting with 30db (max) gain while trying to measure RSSI on the RX2
channel and experiencing about 40db of energy leakage from the TX/RX. My TX
and RX chains are separated by 50MHz. Not sure how I can filter it out.
I'm
Looking for an explanation,
File Source - GMSK MOD - GMSK Demod - Head Block - File sinks
Works fine, terminates after x number of bytes have been transferred and
returns.
However:
File Source - Packet Encoder - GMSK MOD - GMSK Demod - Packet Decoder
- File sinks
Does not return after head
How can you restart a flow graph after a head block kills it?
For example, I want to do something like the following:
tb.start()
tb.wait() # head block will terminate
... do some reconfiguration ...
tb.start()
However, I get a seg fault if I ever try to call tb.start() after the head
block
How can we diagnose make test failures? All tests passed initially, but I
had GRC disabled, so I recompiled everything w/ GRC enabled and this test
failed.
Also, is there a way to re-compile just parts of gnuradio, instead of
recompiling everything?
99% of tests past, only qa_fft_filter failed
Has there been any progress on this bug?
Would this effect performance enough to cause The under run uUuUuU at 250k
sample rate on a beaglebone black (1ghz arm v7- nothing running)?

The volk test is failing on my gnuradio build on a Beaglebone Black
(armv7h) running Arch Linux Arm.
Configuration that failed to enable:
gr-ctrlport *** disabled [do i need this?]
gr-comedi *** disabled [don't need]
gr-qtgui *** disabled [don't need]
gr-documentation *** disabled [don't need]
