I'm trying to connect to the MindWave neuroheadset via bluetooth. Does not work.
Sketch
#include "BluetoothSerial.h"
#if !defined(CONFIG_BT_SPP_ENABLED)
#error Serial Bluetooth not available or not enabled. It is only available for the ESP32 chip.

BluetoothSerial SerialBT;
String MACadd = "20:21:04:08:39:93";
uint8_t address[6] = {0x20, 0x21, 0x04, 0x08, 0x39, 0x93};
String name = "MindWave";
const char *pin = "1234"; //<- standard pin would be provided by default
//const char *pin = "0000";
bool connected;
void setup() {
Serial.begin(115200);
//SerialBT.setPin(pin);
SerialBT.begin("ESP32test", true);
SerialBT.setPin(pin);
Serial.println("The device started in master mode, make sure remote BT device is on!");
// connect(address) is fast (upto 10 secs max), connect(name) is slow (upto 30 secs max) as it needs
// to resolve name to address first, but it allows to connect to different devices with the same name.
// Set CoreDebugLevel to Info to view devices bluetooth address and device names
//connected = SerialBT.connect(name);
connected = SerialBT.connect(address);
if(connected) {
Serial.println("Connected Succesfully!");
} else {
while(!SerialBT.connected(10000)) {
Serial.println("Failed to connect. Make sure remote device is available and in range, then restart app.");
}
}
// disconnect() may take upto 10 secs max
if (SerialBT.disconnect()) {
Serial.println("Disconnected Succesfully!");
}
// this would reconnect to the name(will use address, if resolved) or address used with connect(name/address).
SerialBT.connect();
}
void loop() {
if (Serial.available()) {
SerialBT.write(Serial.read());
}
if (SerialBT.available()) {
Serial.write(SerialBT.read());
