Yes, it is a good starting point indeed, but for example if one doesn't
use the replay block it is not clear how to do the frequency tune.
I had to discover myself that it is possible to send the tune request
action also from the streamer and not from the replay block.
For someone starting with the project it is not so clear.

Hi,
Have you had a look into rfnoc_replay_samples_from_file.cpp? It shows
basic TX setup and also utilizes the replay block.

*Subject:* [EXTERNAL] [USRP-users] Tx example with RFNoC missing
Hi, I noticed that on the UHD repository examples there isn’t an
example that shows how to setup a TX streaming using RFNoC. There is
the example for the RX but not the one with TX.
There’s an example for the replay block, but it can’t be used for
transmitting a big file for instance.
I searched through the mailing list and found some posts of user that
attached some rfnoc_tx_from_file, but they did it in 2018 and it was
on UHD 3, it obviously doesn’t work on UHD 4.
Could someone post a simple example of transmitting from file using
RFNoC 4?
Maybe it is considered trivial, but it could help as a reference.
Personally I tried to write a sample code, but as I stated in another
thread I’m not sure it is working correctly.
Could anyone help here?
