I have a project by using Elechouse Voice recognition module V3 as a sound recognizer, after my command recognized by VoiceRecognizer V3, i want my bluetooth send some character to Android phone, everything run Okay but when i say send to my recognizer my bluetooth cant send character. Anyone can solve my problem ? I use SoftwareSerial .listen() to separate the working of two serial communication but didnt success,.
Maybe someone ever use this recognizer. I use sample program from this recognizer to modified. this is my program : my configuration pin include inside my program :
#include <SoftwareSerial.h>
#include "VoiceRecognitionV3.h"
/**

* 10 -------> TX
* 9 -------> RX
*6 ------> TX(HC-06)
*5 ------> RX(Voltage divider)
*/
VR myVR(10,9); // 10:RX 9:TX, you can choose your favourite pins.
SoftwareSerial myBT(6,5); //BT pin
uint8_t records[7]; // save record
uint8_t buf[64];
int led = 13;
String bt="HELP";
char inbyte;
