Hardware Configuration

N/A

Version

v2.0.0

IDE Name

Arduino IDE

Description

Error when using BluetoothSerial.h libarary the example sketch SerialToSerialBT fails to compile.

I'm not sure what the problem is. I didn't see anything in the readme mentioning the need to define or modify any variables in the SerialBluetooth.cpp file.

Any help or advice would be greatly appreciated. I'm trying to get this up and running for a Halloween costume.

Sketch

//This example code is in the Public Domain (or CC0 licensed, at your option.)
//By Evandro Copercini - 2018
//
//This example creates a bridge between Serial and Classical Bluetooth (SPP)
//and also demonstrate that SerialBT have the same functionalities of a normal Serial

#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

#if !defined(CONFIG_BT_SPP_ENABLED)
#error Serial Bluetooth not available or not enabled. It is only available for the ESP32 chip.
#endif

BluetoothSerial SerialBT;

void setup() {
  Serial.begin(115200);
  SerialBT.begin("ESP32test"); //Bluetooth device name
  Serial.println("The device started, now you can pair it with bluetooth!");
}

void loop() {
  if (Serial.available()) {
    SerialBT.write(Serial.read());
  }
  if (SerialBT.available()) {
    Serial.write(SerialBT.read());
  }
  delay(20);
}

Looking at the paths that give error, you are not using this core's Bluetooth Serial library, but some other one located in your sketch folder: C:\Users\eshel\OneDrive\Documents\Arduino\libraries\Bluetooth Serial

I compile for first time a esp32 bluetooth example and give this error "Bluetooth is not enabled! Please run make menuconfig to and enable it"

board manager is https://raw.githubusercontent.com/espressif/arduino-esp32/gh-pages/package_esp32_index.json

So... the problem is that in BluetoothSerial.h call sdkconfig.h but in \AppData\Local\Arduino15\packages\esp32\hardware\esp32\2.0.5\tools\sdk\esp32 is declared sdkconfig without h extension

So i put .h a sdkconfig and working fine sdkconfig.h

also can see here https://github.com/espressif/arduino-esp32/tree/master/tools/sdk/esp32 that all packages contain sdkconfig not sdkconfig.h
