Voice recognition module :Recognition stage problem.
Posted: Fri Dec 16, 2016 11:56 pm
Hello, I'm writing regarding your Geeetech VR module, as I'm facing two problems.
The first problem:
The first problem, is the TTL device, after a while, it's gets kinda an "open" circuit. It is not recognizable by the computer (I'm using windows 7, and an Hterm software), even though the Voice recognition module LED is contentiously blinking, as well as the TTL's LED which is still on. I tried using it on different USB ports but no use (neither windows or the software is aware that a USb is connected), so I had to order new TTLs. I ordered two as a back up as I have an urgent upcoming project.
I understood the recording method, and did it pretty well, did not face a lot of issues.
I then have to disconnect the module from the TTL, as it obviously saved my voice commands in hex forms, and then connect it to my arduino mega 2560. I would power up the module using the arduino 5V power output pins, once this is done, you'd usually hear a "USB" sound notification from the computer.
The purpose of this module is to control my linear actuator, via HIGH and LOW outputs after it recognizes the command (via the "Switch case" codes), and I did copy and paste the sketch that is found on the device' wiki link.
The second problem:
But here is second the annoying yet strange problem, once connected the to the arduino, the voice module sometimes isn't just ready for the voice recognition stage! the LED keeps blinking fast (waiting for a serial instruction), and after numerous attempts, it was "ready" for voice instructions for 3 or 4 times by having a "pulse" like blink, just like the one you would see in the recording stage (please speak). Once that was achieved, my linear actuator responded perfectly. However most of the time, the LED blinks continuously, and is obviously not in the recognition stage mode.
I don't know what is the problem, I kept connecting the disconnecting the 5V VDD ports, the Rx and TX (although this one doesn't need a TX) pins before uploading, but the problem is still there and looks very random!
I even though of checking if the module forgot my instruction by reconnecting it to the computer and sending a AA 21 code through the software to test, but it seems that the instructions are still there with the correct hex responses.
Please help me as soon as you can regarding the arduino issue, I would really appreciate it, because I'm in real real hurry but stuck. I fear that this will embarrass me during my upcoming presentation.
