ASAMMDF does not read my data there is onely "b' '" in the Samples

[RacingMonkeyCode]

Hi,
ASAMMDF does not read my data there is onely a b' ' in the Samples. I know the Samples are there in the MF4. I can read them with CANape and other tools.
Is there som other way to import the MDF?

What is the output of this?

ch  = mdf.get(channel_name, raw=True)
print(ch)

This data looks quite valid. I don't really understand it, I had actually tried raw=True, but maybe I was at get_can_signal.

ch  = mdf.get('channel_name',raw=True) 
print(ch)
ch  = mdf.get_can_signal('channel_name', raw=True)
print(ch)
