I’m following @janjongboom’s steps and I am able to get the Micro:bit working with his keyword "Micro:Bit and the LED display shows the smiley face. When I try and run my own keyword, I can verify in the serial terminal that it’s correctly predicting my keyword but I lose the smiley face on the Micro:Bit to verify it that way. I’m using what @aureleq taught us in his workshop to use Docker to do the build.
Have you set your keyword here? https://github.com/edgeimpulse/voice-activated-microbit/blob/master/source/MicrophoneInferenceTest.cpp#L32 It needs to exactly match the label in the Studio.
