Voice Recognition Module Not Responding properly

[quique]

Hi guys

Yesterday I tried my VR module. At first it wasn't recognizing any sound I would get Start....No Voice...Start...No Voice.

I stopped using the microphone you include and I used a different mic connected directly to the terminals provided on the board for VOC and GND. This worked and I was able to record 5 commands for group 1.

Then I used the module in a sketch and it worked.

Then I tried re-recording new commands always for group 1 (and i later even tried for group 2) but whenever I send the command, any command to the module now, all I get is @A @B @C, not in that order.

What has happened and how can I fix this?

Here is a CoolTerm capture:

I also noticed my sketch does this:

Code: Select all

  Serial.write(0xAA);
  Serial.write(0x37);
  delay(1000);
  Serial.write(0xAA);
  Serial.write(0x21);

in the setup and then I disconnected it and tested the module by powering it from a battery pack.

But I noticed the Serial Monitor output this just before I disconnected it:

Code: Select all

�7�!

try changing the port speed to 9600 on the module by entering the command: AA 33
