I have this challenge of receiving data when I send a command to voice recognition v3 module. the uart connections are okay, but when I send a command I don't receive a response on the terminal. the prolific usb-ttl with drivers installed blinks when I send a command but still I get no response. please help in debugging.

  • Can you be more specific about what you have done. E.g. show your code, circuit and the "commands" used. – MichaelT Oct 25 '18 at 15:51
  • I am using ACCESS PORT in trying to train the module as per the manual commands. But haven't achieved any success. Any suggestions please? – Bibby_muthandi Oct 31 '18 at 18:12

The module can't communicate with Serial Monitor over a USB to TTL Serial adapter. It uses binary communication. Use Arduino, Arduino library and one of the example sketches of the library to communicate with the VR module.

And read the manual.
