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 ?

Hi @ei_francesco

No, with the edge-impulse-daemon I can connect to edge impulse and the device is on green and connected so I can click on “start sampling”

#4

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

#5

Yes, than nothing happens.

I downloaded the audio firmware from here: Arduino Nicla Voice - Edge Impulse Documentation

and flashed the flash_windows.bat

Thats the log when I try the “edge-impulse-daemon --verbose”-command and start sampling:

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.

regards,
fv

Hi @ei_francesco

sry for asking, but I dont know which command you mean :sweat_smile:
Should I run the command in my console? And what does this command do? I couldnt find something helpful on the internet when I google “format_ext windows command”

Thank you.

#9

Hi @gom9sgm ,

you can find the file in the zip.

For win, the file is format_windows_ext_flash.bat

let me know
