You’ll need to use timed commands for tuning, in order to phase align the LOs.
Unfortunately there is no direct support for this in GRC. So you’ll have to
edit the output code from GRC to change you tuning functions.

I am trying to connect my E310 (sg1) to the internet with a WIFI Dongle

Hi Rajesh - Sorry for the delay. Which branch / commit of gr-ieee802-11 are
you using? The version of GR is pretty old (3.7.6), and there's a
reasonable chance it's not compatible with the version of gr-ieee802-11 ...
but it could be something else too. Otherwise, yes, the settings you list
look
Looks like you built the master branch of GNU Radio, which defaults to
Python 3. To resolve those failing tests, you need python3-scipy and
python3-zmq.

Hi Rajesh - CMake found your GR38 install, not your GR37 install. You
should pick GR37 or GR38 and go with just it, and remove the one you're not
going with. Then, pick the same branch of gr-ieee802-11. Hope this is
useful! - MLD

Hi Rajesh - The block "OFDM Sync Short" is part of the GR out-of-tree (OOT)
module "gr-ieee802-11" ... as are many of the other blocks in the image you
provided. If that OOT is not installed already, it shouldn't be difficult
to do so. Hope this is useful! - MLD

Adding library in CMakeList.txt and setting environment variable
LD_PRELOAD=/usr/local/lib/"my lib" fixed the original problem.
I did not have to set --whole-archive option.
Thank you.

Just wanted to follow up on this, because I thought of something in the
shower this morning.
If you compile your block controller as a shared library and you want your
block to be initialized/used with the default UHD apps, you can use
LD_PRELOAD to ensure the block registration happens at

Using:

We are able to use our controller.

OK, I looked further into it. UHD registers out-of-tree block controllers
using the UHD_RFNOC_BLOCK_REGISTER macro, which under the hood creates a
static function and a fixture which calls it before main(). Problem is,
when linking your out-of-tree executable, the linker sees that the static

Make very sure that your program is actually linking in the library

Your program needs to be linked against the library which your custom block
