Ive tried using the Elechouse voice recognition v3.1 for a while now and I keep getting this error message:
I send “train 1”:
“Train with signature failed or timeout.”
I send “settings”:
“Check system settings error or timeout”
Ive checked the wire many times. Its TXD-2 RXD-3.
Im using the the VoiceRecognitionV3 library.
Adding a screenshot.
