Err("Data not recordable") From data_request.py Example

[billyen33]

I tried running my data_request.py example from this repository with my nScope v1 and got the error seen in the title from line 13:

data = nlab.read_all_channels(sample_rate, number_of_samples)

I verified that my nScope is connected by running the list_all_nlabs.py example and also was able to successfully print out power from the monitor power example. This is the output from list_all_nlabs.py:

List of all detected nScopes:
Link to nLab v1 [ available: true ]

Is there a reason why this doesn't work? I used the example as-is and did not change anything. The error is:

Err("Data not recordable")

After this error the kernel just hangs here. I would like to access the nScope voltage readings via Python so I can write some additional code to use it as a logic analyzer.
