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);

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??

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
