I've recently purchased and installed a voice command module on my Nybble, but cannot get it to mechanically work.
I've tried using the original fully working Firmware using Voice mode and I've also tried using the latest Firmware
In BOTH cases "play sound" works and I get a verbal response from the module (in English) for every command I that I try
The problem is that Nybble is disobedient and never responds to any commands!
I have the voice command module plugged into D8 and 9 and I have plugged and unplugged both ends of the cable many times but no change
Have you tried the debugging routine at https://docs.petoi.com/extensible-modules/voice-command-module#how-to-debug-if-the-voice-command-doesnt-work ?
I also notice that the desktop app you use is an old one. Please download the latest one at: https://github.com/PetoiCamp/OpenCat/releases/tag/1.2.0
