How To connect GR PEACH Board with Bluetooth?

How about the following sample? It is likely to work If you change the Serial terminal.

A change example of a Serial terminal.
  Serial Blue(p28,p27);
  ->
  Serial Blue(P8_14,P8_15);

Other bluetooth modules.

Hi Okamiya Yuuki,

How to connect HC05 with GR PEACH Board?  I tried with Arduino code and interfacing type by connecting TX,RX pins.Its is not working here.Why??

In reply to Suresh:

Hi Suresh,

We have interfaced HC05 successfully with the GR Peach. As HC05 (Tx and Rx) supports 3.3V you can connect directly it to GR Peach no need of Voltage-Level Translator. Just connect the Tx pin of HC05 to Rx Pin of GR Peach and Rx pin of HC05 to Tx pin of GR Peach.

GR Peach has 7 channels for UART communication. 

Serial0: 0(RX), 1(TX) 
Serial1: 41(RX), 42(TX) 
Serial3: 25(RX), 26(TX) 
Serial4: 8(RX), 9(TX) 
Serial5: 7(RX), 6(TX) 
Serial6: 22(RX), 23(TX) 
Serial7: 63(RX), 64(TX)

In my project i connected the HC05 to Serial4 and used Bluetooth to send data to GR Peach and show the same data on the PC serial monitor.

#include<Arduino.h>

String inString = "";    // string to hold input

void setup() {
 Serial.begin(9600);
 Serial4.begin(9600); //set baudrate(9600) accordingly
}

void loop() {
 // put your main code here, to run repeatedly:

if(Serial4.available()){
    while(Serial4.available())
      {
        char inChar = (char)Serial4.read(); //read the input
        inString += inChar;        //make a string of the characters coming on mySerial
      }
      Serial.println(inString);
      inString = "";  
  }
}

Hope you find this useful!!

Hi D_Amol,

I tried your code,Still i didnt get any value in serial monitor.Will u pls send your serial monitor screenshot.

@Suresh

check whether TX of your module is connected to RX of the Serial4 and vice-versa.

check your baud rate
