    FAQ

    • Can you share the code that you used for the project video which you posted here on youtube for this module:

      Hi thanks for responding.

      I think the sample could show more usage of the other commands. There are 26 commands in the wiki and the sample shows how to use 2 of them. I added one file 1 (17.mp3) onto the module, then updated the sample code to "call play(0x11)" and nothing plays.

      The video is using sounds that you've added, so I'd like to see that code to see how you were able to make that happen.

      Also, can you tell me how to replace the files. Even after I delete all the default sample files, they still are playing. IF I replace them with other files, they still play the old sounds. I'm just connecting the module to the computer, opening up the ZH folder and removing, or replacing, but when I connect back to arduino, same sample files play.

      Thanks.
