Dear all, I have problems to get the example "wifi_tx.grc" from gr-ieee802-11 [1] to work with my HackRF device. In the example, I just replaced the USRP sink with the osmocom sink and tried to run it. I always get underrun errors:

I also tried the latest gr-osmosdr v0.1.4-91-gcf954948 version but without any luck. I'm also using the latest firmware (2017.12.01) of my HackRF device. I asked [2] Bastian Bloessel, the author of gr-ieee802-11, but it seems like it is a general problems with tagged stream blocks and my HackRF device. As he mentioned, I created a simple GNU radio file like the following: Message Strobe -> Random PDU -> PDU to Tagged Streams -> Osmocom Sink Also in this example, I get a lot of underrun errors. Does anyone have an idea what might be the problem? GNU Radio Version: 3.7.11 and 3.7.9 HackRF Kernel Module: 4.10.13-1-ARCH Gr-osmosdr: 0.1.4 and v0.1.4-91-gcf954948 Thanks in advance!
