Audio_char information Text , How to seperate each Info a a own char ?

[Micha2007fe]

Hi,
I use this great lib and now I try to send the audio_char text . e.g.

• audio_info
• audio_showstation
• audio_showstreamtitle

.... to an second ESP over Uart....

Can anybody help me please and advise me , how to seperate each to a own char or string ?

Char 1 or string 1 = audio_info
Char 2 or string 2 = audio_showstation

and so on....

I say many thanks for any tips and hints ....

Hello Micha2007fe,
I suspect you have a setup similar to this: https://quadmeup.com/arduino-esp32-and-3-hardware-serial-ports/
and connected with 3 wires for bidirectional transmission (ground, TX and RX crossed)

then put a number in front of the data packet, for example, so that the recipient can assign the packets

transmitter

#include "HardwareSerial.h"
HardwareSerial MySerial(1);
void setup() {
    Serial.begin(115200);
    MySerial.begin(115200, SERIAL_8N1, 13, 14);
    ....
}
// optional
void audio_info(const char *info){
    Serial.print("info        "); Serial.println(info);
    MySerial.printf("%c%s\n", 1, info);
}
void audio_showstreamtitle(const char *info){
    Serial.print("streamtitle ");Serial.println(info);
    MySerial.printf("%c%s\n", 2, info);
}

receiver

HardwareSerial MySerial(1);
void setup() {
    Serial.begin(115200);
    MySerial.begin(115200, SERIAL_8N1, 13, 14);
    ....
}

void loop(){
    ....
    if(MySerial.available() > 0){
      int8_t r;
      String info, st;
      r = MySerial.read();
      if  (r == 1) {info = MySerial.readStringUntil('\n'); log_i("info: %s", info.c_str());}
      if  (r == 2) {st   = MySerial.readStringUntil('\n'); log_i("streamtitle: %s", st.c_str());}
    }
}
