Nicla Voice and its Bluetooth support

Official Hardware Nicla Family Nicla Voice

Hi everyone,

I’m genuinely frustrated with the Nicla Voice and its Bluetooth support. For a product that’s presented as professional-grade, I did not expect it to be this difficult to get even a basic BLE peripheral working.

What I’ve already tried

  1. Followed the official firmware update procedure for the NDP (the three files: patch, network, parameters). Update completed without errors.
  2. Tested multiple BLE example sketches (and my own minimal sketch below).
  3. Tried several phones and BLE scanner apps.
  4. Power-cycled the board, pressed RESET, re-flashed the sketch, reinstalled the core and libraries.
  5. Verified serial output—sketch reports that BLE starts and advertises.
  6. Tried different service/characteristic UUIDs and shorter local names.
  7. Swapped USB cables/ports and ensured stable power.

Arduino, you must be able to do better.

Where is that posted?

What exact sketch are you running and what problem do you have? You don't specify what's wrong as in, you don't see the BLE adverstisment on the phone, you can't pair with the device, a specific service or attribute doesn't exist or the data from it is unexpected?

Hi, I apologize. But I'm just so frustrated. I updated the firmware via this link. https://docs.arduino.cc/tutorials/nicla-voice/getting-started-ml/ Then I installed the bluetooth code from this link https://docs.arduino.cc/tutorials/nicla-voice/user-manual/

I can see the device using the iOS app LightBlue "VoltageMonitor" but I'm never allowed to connect.

And to exclude the possibility that this is iOS specific you tried this on an Android phone too? The tutorial references nRF Connect for Mobile and shows a screenshot of an Android device.

I have also tried the "nRF Connect" app on my iPhone. I also work with Portenta C33 and it works perfectly with iOS. So I didn't expect Nicla voice to cause problems??? Has anyone gotten Nicla voice to work with iOS?

Unfortunately you were deceived by the advertising, but if you had carefully looked through the getting started guides and examples before buying, their superficiality would have been obvious.

The Nicla Voice and similar products could be viewed as "work in progress", except there has been little to no progress since their introduction. They might more accurately be seen as dead ends.

This forum has many complaints similar to yours.

Thanks for the reply and have a good day. :slight_smile:
