I am trying to connect ESP32 via bluetooth classic to my PC to transfer some data from a sensor.
As a first step, I am simply trying to send some random data over bluetooth serial. The code is at follows:
#include "BluetoothSerial.h"
#if !defined(CONFIG_BT_ENABLED) || !defined(CONFIG_BLUEDROID_ENABLED)
#error Bluetooth is not enabled! Please run `make menuconfig` to and enable it
#endif
int myData[8];
BluetoothSerial SerialBT;
void setup() {
Serial.begin(115200);
Serial.println("Opening Serial Connection on COM4");
SerialBT.begin("ESP32"); //Bluetooth device name
SerialBT.println("Opening Serial Bluetooth Connection on COM6");
}
void loop() {
for(int i = 0; i < 8; i++)
{
myData[i] = random(0,500);
}
if(Serial.available())
{
for(int i = 0; i < 8; i++)
{
SerialBT.write(myData[i]);
}
}
delay(20);
}
In Windows Bluetooth settings, I have paired the ESP32 with windows and connected it. I have set up incoming and outgoing COM ports for Bluetooth where incoming port is COM6 and outgoing port is COM5.
However, when I open the Arduino serial monitor for COM6, it is empty and no data is being printed. I am using the Arduino IDE. Furthermore, on COM4, there is nothing printed despite the Serial.println("Opening Serial Connection on COM4"); command which I think should work regardless of Bluetooth.
I have tried everything I can think of. I would be grateful if anyone can help me solve this problem as I have been stuck for days.
