I'm actually on 3.9.5 but I will investigate on the PDUs to know if it

Hi Fabien,
Personally, I use PDUs to control when TX starts. GR 3.10 integrated a
lot more of these.

Besides, the gr-pdu_utils OOT might be a good reference.

Hi Johannes,
Yes this is exactly my problem : after unlocking the flowgraph, I get
some underruns (only, no overrun).
Do you have an example of code using EOB/SOB ? Ok for sending EOB before
locking but is it necessary to send a SOB also and when ?
Your suggestion of idling the TX flowgraph
Hi Fabien,

or vice versa? Do you see overruns as well?
I'd assume the USRP expects a constant sample flow and even a short
interuption, like your lock/unlock task interrupts that flow.
Still assuming this is the root caus
