Delete Matrix Voice Internal Program

Hi,

i have installed the demo on my matrix voice: https://www.hackster.io/matrix-labs/get-started-w-esp32-on-the-matrix-voice-d01e0d
This demo is loaded directly into the ESP32 so it is independent from my raspberry pi.
Now i want to install snips.ai as described here: https://www.hackster.io/matrix-labs/matrix-voice-and-matrix-creator-running-snips-ai-b48344
Somehow it seems that there is a problem with my matrix voice, since it does not record any sound.
I guess it is because there is still the demo running on the internal chip.

How can i reset this programm so that i have my matirx voice on factory defaults?
Thanks in advance for your Help!

I already had a look at this comment: [Solved] Reseting Matrix Voice ESP32 software in order to run Alexa demo?

But i am not sure where and how to run the commands to reset the interal program…

I use my own method:

  • ssh into the pi, execute this command: voice_esp32_enable. If you get a permission denied, execute the command again.
  • esptool.py --chip esp32 --port /dev/ttyS0 --baud 115200 --before default_reset --after hard_reset erase_flash
  • reboot the pi

Funny that you mention no sound recording, I also came across that but when I flashed again it was working again…
