TypeError: argument of type 'NoneType' is not iterable. This problem disappeared on two devices, not sure why, but it stays present on the rest of the devices and I am thus unable to use my PlutoSDRs on these devices as a result. I was hoping somebody knows if this is a common issue or if somebody managed to fix this in the past. Cheers! DBK. You signed in with another tab or window. Reload to refresh your session.
