Question/Issue:
On Ubuntu 24.01 connecting to Grove Vision AI Module V2 via edge-impulse-daemon, device is shown in device list. Collect-Data for camera seems to work. Collect data for microphone fails with error message “Failed to start sampling - sample length is too long, maximum allowed 0 ms”.
Changing to 0ms triggers sampling at the device - but returns no data 
Project ID:
Context/Use case:
Want to use the board for voice-sampling.
Summary:
Error message on start of sampling via microphone:
“Failed to start sampling - sample length is too long, maximum allowed 0 ms”.
Steps to Reproduce:
- Connect device via command-line
2.Check device is visible - Data collection for microphone
Expected Results:
Sampling to start
Actual Results:
“Failed to start sampling - sample length is too long, maximum allowed 0 ms”.
When using with “0” connections works, but doesnt sample anything
Reproducibility:
- [x] Always
- [ ] Sometimes
- [ ] Rarely
Environment:
Ubuntu 24.01 LTS
