Serial Bluetooth and receiving/ storing strings

Projects Programming
1

Hello,
I use SerialtoSerialBT example of Arduino IDE (hereunder).
I need to put following strings in my ESP32 'PowerOn, PowerOff, Rec, Stop'. These strings are issued from a Smartphone linked thru Bluetooth.
All is working... , but I need them to be stored inside ESP32. Each trial to put 'char' strings in the loop gave weird additional characters or loss of characters. Any idea/ help to store in buffers instead of just printing in Serial Monitor ? Thanks for help and advice.


BluetoothSerial SerialBT;

void setup() {
  Serial.begin(115200);
  
void loop() {
  if (Serial.available()) {
    SerialBT.write(Serial.read());
  }
  if (SerialBT.available()) {
    Serial.write(SerialBT.read());
  }
  delay(1);
}

Hi bernhard,

serial.read() read a single byte.

Be the change you want to see in the world

This notion of be the change you want to see in the world does 3 powerful things when we adopt it:
It stops us from judging others;
It replaces complaining about others with reflection on self;
It stirs us into taking action within the only thing in the world over which we have any control: ourselves.
