Description
I am using the sample program that comes with the board: BletoothSerial -> bt_classic_device_discovery. but when I compile the program, I find that I get the error "#error Serial Bluetooth not available or not enabled. it is only It is only available for the ESP32 chip.", which seems to be caused by the esp32s3 not defining CONFIG_BT_SPP_ENABLED.
Sketch
#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;
#define BT_DISCOVER_TIME 10000
static bool btScanAsync = true;
static bool btScanSync = true;
void btAdvertisedDeviceFound(BTAdvertisedDevice* pDevice) {
Serial.printf("Found a device asynchronously: %s\n", pDevice->toString().c_str());
}
void setup() {
Serial.begin(115200);
SerialBT.begin("ESP32test"); //Bluetooth device name
Serial.println("The device started, now you can pair it with bluetooth!");
if (btScanAsync) {
Serial.print("Starting discoverAsync...");
if (SerialBT.discoverAsync(btAdvertisedDeviceFound)) {
Serial.println("Findings will be reported in \"btAdvertisedDeviceFound\"");
delay(10000);
Serial.print("Stopping discoverAsync... ");
SerialBT.discoverAsyncStop();
Serial.println("stopped");
} else {
Serial.println("Error on discoverAsync f.e. not workin after a \"connect\"");
}
}
if (btScanSync) {
Serial.println("Starting discover...");
BTScanResults *pResults = SerialBT.discover(BT_DISCOVER_TIME);
if (pResults)
pResults->dump(&Serial);
else
Serial.println("Error on BT Scan, no result!");
}
}
void loop() {
delay(100);
}Debug Message
bt_classic_device_discovery:8:2: error: #error Serial Bluetooth not available or not enabled. It is only available for the ESP32 chip.
#error Serial Bluetooth not available or not enabled. It is only available for the ESP32 chip.

Using library BluetoothSerial at version 2.0.0 in folder: C:\Users\mengd\AppData\Local\Arduino15\packages\esp32\hardware\esp32\2.0.7\libraries\BluetoothSerial
exit status 1
#error Serial Bluetooth not available or not enabled. It is only available for the ESP32 chip.
Other Steps to Reproduce
It looks like all the sample programs in BletoothSerial are not available on the ESP32-S3 series.
I have tried commenting out the program:
//if !defined(CONFIG_BT_SPP_ENABLED)
//#It is only available for the ESP32 chip.
//#endif
But it brings more error messages with undefined files:
undefined reference to esp_spp_disconnect' undefined reference to esp_spp_deinit'
undefined reference to `esp_spp_write'
