Here's a way in Python you can pull in SC16 and recover the FC32 from a
file. It'll scale the values from the INT16_MAX back to -1.0 to 1.0 too in
one shot.
import numpy
file="somefile.iq"
dat = numpy.fromfile(file, dtype=numpy.int16)
data = dat[0::2]/32767.0 + 1j*dat[1::2]/32767.0 # ::02 says
arameter in the advanced file sink.

Morning everyone, not sure my note yesterday hit the list correctly so I'm
trying again.
Mark: I have a solution for you. I added a new block yesterday to
gr-filerepeater (pybombs or github). There's now a state timer block
that'll generate a message based on block-specified timing. Trigger
Hi Mark,
If you look at gr-filerepeater (https://github.com/ghostop14/gr-filerepeater
or from pybombs), I just recently added an advanced file sink to the
module. One thing it has is a message port that you can pass a state key
in the metadata to (1 to record, 0 to stop).The block will also
I second RFNoC for the B series would be great. They're an incredibly
popular and affordable series and I feel a little left out of the
capabilities of RFNoC due to the Spartan6. Bringing the Artix to the
B-series or supporting the Spartan6 could both be options I'd love to see.

Hi folks,
I have a weird issue I've been attempting to troubleshoot for a bit and I'm
stuck.
So setup:
USRP B205 connected to a Raspberry Pi 3 (so USB 2 mode)
Huawei E3372 USB LTE adapter connected as well
Running the latest Raspbian (stretch)
Problem:
I'm using C++ code to read stream blocks
