SEN0539 Offline Voice Recognition Module - No Serial output
Jason.Davies 2023-09-03 14:16:47 1164 Views7 Replies Hi
I am having problems with the offline voice recognition module connected to Arduino via the DFRobot IO expansion Shield V7.1
Using the example code from the GitHub or the code from the wiki page - the code compiles & uploads fine but i get no output on the serial monitor! Also the demo code from the wiki the light does not turn on or off
Running the normal “Blink” sketch the LED works fine
I get audio response to my voice commands ok so i know the board is working
I have tried both Arduino IDE V 2.2.1 & V 1.8 = same result
I have tried different models of Arduino UNO - same result
I have tried a simple serial.print test - works OK
I have tried
I am running on Linux Ubuntu 20.04
Any help / advice would be much appreciated
To ensure proper functioning of a module, ensure proper wiring, power supply, baud rate, firmware/configuration, correct library/code, and module status. Double-check connections, power supply, baud rate, firmware/configuration, and library/code settings. Verify that the module is trained with voice data and has the correct libraries and code
pisowifi To troubleshoot the SEN0539 Offline Voice Recognition Module, ensure it's properly powered, the baud rate matches the module's default setting, check [url=https://100001.su/]10.0.0.0.1[/url] - [url=https://100001.su/]10.0.0.1[/url] TX/RX connections, and test with a simple example code to rule out software issues.
You should try communicating with the module using UART. Its default baudrate is 9600. Make sure to connect the ground pins of your module and your Arduino.
bradjshannon Hi I'm having similar issue. It is in I2C mode. Do you have a solution?
Thomas.Verpraet Does the module have the I2C setting active, or do you need to switch to UART interface mode? Mine arrived today with the switch already in the I2C position.

Robert.Riddle Sounds like you need to use UART interface mode, is the module set to I2C? I have only just received mine, and the switch was set to I2C.
