Hello, I am a French teacher and I am having difficulty using the Seed Groove V3.01 module.
This module does not respond to any AT command And I would like to change their HmSoft ID to another Name. How should I go about it? I am using an Arduino R3 board coupled to a Groove 2.1 shield.
Im using this code
#include <SoftwareSerial.h>
SoftwareSerial hc06(8,9);
void setup(){
Serial.begin(9600);
Serial.println(“ENTER AT Commands:”);
hc06.begin(9600);
}
void loop(){
if (hc06.available()){
Serial.write(hc06.read());
}
if (Serial.available()){
hc06.write(Serial.read());
}
}
Looking forward to an answer from you, please accept my greetings. Mr Leroy
Hello,
please have a look at the line of ‘AT+BIND’ in the command list. And send it from your computer to your Arduino then to your grove.

I hope the information can help you.
Hey, i try the AT+BIND:?, it’not working to.
I change my code and i use this :
#include <SoftwareSerial.h>
#define RxD 2 //Pin 2 pour RX (pin0=serial) vert
#define TxD 3 //Pin 3 pour TX, on peut changer noir
SoftwareSerial BTSerie(RxD, TxD);
void setup()
{
Serial.begin(57600); //115200 si on veut
delay(500);
Serial.println(“Boready for AT Commands”);
// Configuration du bluetooth
pinMode(RxD, INPUT);
pinMode(TxD, OUTPUT);
BTSerie.begin(57600); //57600
delay(500);
BTSerie.print(“AT”); //ASk for AT ready
delay(1000);
BTSerie.print("\r\n");
Serial.print (“Asking”);
}
void loop()
{
char recvChar;
//On lit caractere par caractere sur le BTSerie et on affiche sur le Terminal Serie
if (BTSerie.available()) {
recvChar = BTSerie.read();
Serial.print ("receipt msg : ");
Serial.print(recvChar);
}
//Serial.print(BTSerie.read());
if (Serial.available()) {
recvChar = Serial.read();
BTSerie.write(recvChar);
Serial.print ("Send AT command : ");
Serial.println (recvChar);
}
}

but no answer… WHY ??? I’don’t understand why the Bluetooth Module not responding to my AT order.
Somebody can help me ?
Bonjour, j’ai eu le même souci, le module ne semble que répondre en 115200 bauds.
