Here's a picture of my flowchart:
[image: gnuradio-runtimeError-bad_alloc.png]
Tested this on a different machine, and it works fine, so the problem isn't
with the flowchart itself. I'm working off the maint-3.8 branch, installed
from source.
An
there that are compatible with the HackRF AND gnuradio 3.8?
Thanks!

Has anyone else encountered this issue, or is aware of a solution? I'm on a
Fedora 29 machine, with every python qt4/5 library installed via pip.
Thanks!

l's gr-ieee802-11 repo so far, but it looks like I'll need
another approach.
Is there another method that could transmit 802.11 packets that would work
with the HackRF?
Thanks!

Bumping this, still can't figure out how to turn a binary file source into
a PDU that I can transmit. Any advice would be appreciated.

that into parameters for the osmocom source, which has 3
gain options: RF gain, IF gain, and BB gain, all in dB.
I tried setting the RF gain = 20log(.75) = -2.49877, but that just resulted
in mangled packets.
Any suggestions?
