The SerialToSerialBT compiling failed for ESP32S3 why?

[lladam]

Hi all,
the compiling for ESP32 Dev Module passed, failed for ESP32 S3, why and how to fix?
Thanks
Adam

Code: Select all

#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);
}

This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.

I think the error message could not be any clearer.

It is only available for the ESP32 chip.

The original ESP32 has the required hardware for SPP (Bluetooth "classic", or "BR/EDR"), the ESP32S3 does not (BLE only); so nothing that could be fixed here.
