Unable to connect Nicla Voice Board to edge impulse for sampling

Help
#1

Hello,

I’m currently trying to connect my arduino nicla voice to edge impulse to sample data with it.

When I use the edge-impulse-daemon, I can connect the board to edge-impulse, but when I try to click on “start sample” in data acquisition it changes to “waiting to start” and after that nothing happens. (Screenshot 1)

After a while I get the “Sampling failed” errormessage. (Screenshot 2)

Also when I try to use the data-forwarder I get the error message from the third screenshot.

Maybe you can help me, thank you.

Hi @gom9sgm

In the screenshot you are using the edge-impulse-data-forwarder, do you have the same error when using the edge-impulse-daemon ?

ok then with the daemon you get “waiting to start” and nothing happens, correct ?
Did you flash the board with an audio model ?

Can you connect with the daemon adding --verbose and past here the log of the connection phase and then when starting a sampling ?

thx

I’ll check, thx for reporting.

Hi @gom9sgm ,

can you try to run the format_ext command for your OS and then flash again ?
I just tested the bin in the zip and is working fine for me.

I’m having the same issue when I try to flash edge-impulse firmware for IMU.
The board is not responding for command ‘b’. Is there a updated version of IMU firmware that has the fix? I’m flashing the firmware using the flash_windows.bat file for IMU which is provided by Edge Impulse here -
