Question/Issue:
When I try to stream audio from my Arduino Nicla Voice into Edge Impulse via the edge-impulse-daemon , sampling immediately fails with a timeout error (AT+SAMPLESTART=Microphone ).

Project ID:
DEEPKAKADIYA-project-1 (635596)

Context/Use case:
I’m building a keyword-spotting model. I need to collect raw microphone data from the Nicla Voice over USB so I can label it and train in Edge Impulse.

Steps Taken:

  1. Installed Edge Impulse CLI (v1.32.1) on macOS
  2. Flash-loaded the pre-compiled Nicla Voice firmware
  3. Ran the provided .sh script to start the daemon
  4. Tried edge-impulse-daemon --clean
  5. Swapped USB cables and ports
  6. Tweaked the AT-command baud rate in the launch script

Expected Outcome:
The daemon finds the Nicla Voice, enters sampling mode, and begins streaming microphone frames into the Edge Impulse Studio “Data acquisition” page.

Actual Outcome:
Sampling immediately errors out with:

Sampling failed  
Timeout when waiting for > (timeout: 35000)  
AT+SAMPLESTART=Microphone

Reproducibility:
100% — it always times out.
