OS: Ubuntu 18.04
Laptop: Dell Latitude 5490
GNU Radio : 3.7.13.5
UHD : UHD_3.15.0.git-1-gf83faf28
SDR: Ettus N200
I did a fresh install today using pybombs.
Then tried running wifi_rx.grc from gr-ieee-80211 package and flooded with
errors. Never seen them before. Bold marked part is coming with all the
programs where I am connected to USRP such as uhd_fft while the rest
happens with wifi_rx.grc (this is what I have observed so far).
However, all the programs are working flawlessly with older version.
Any tips to solve it.
Regards
Sumit
