We have encountered a problem in trying to use our Elechouse Voice Recognition Module V3 (link: http://tinyurl.com/prnf9xu). We have carefully followed the steps mentioned in its manual, but after the part wherein we are instructed to send a command via serial monitor, an error message is returned.
As stated in the manual:
Then, after sending the "settings" command, we get this result:
The connections between the voice recognition module and the Gizduino (Arduino clone) goes like this:
Other steps done:
*Soldered the pins that come with the module, for "better connection"
*Interchanged the RX TX connections
... yet we still get the same result; then we tried a different approach - we connected the RX TX pins of the module to the 0 and 1 pins of the Gizduino (which are labeled with RX and TX). We connected the module's TX to the 0 pin and the module's RX to the 1 pin then edited the part of code to be uploaded that seems to define the RX TX pins to be used
Note: we edited the part VR myVR(2,3) to VR myVR(0,1) since we changed the pins where we are connecting the module to
we uploaded the code but without having connections on the RX TX pins of the Gizduino, then after upload is done, we sent the same "settings" command via serial monitor and instead of the receiving the usual error message, the serial monitor freezes.
By the way, whenever we connect the voice recognition module to the Gizduino, a LED that seems to be indicating power goes on, so I guess our module is still functional.
Since the day we have received the module from the seller, we haven't been able to make it work. We would like to ask for your assistance since we are clueless on where the problem lies. Your help is very much appreciated. Thank you.

*Before arriving into that part wherein a wall of text is flashed on the serial monitor (as indicated on the first image), we have uploaded beforehand a sample "train" code that came from the library mentioned above.
