Till now i am able to connect and send some characters to the esp32 but when i try to split that data nothing happens.
I am using the StringSplitter library to split data. I am able to use it with a String that i initialize in my code but couldn't do that with the data that i got from my phone app.
herer is my code :
Code: Select all
void connectBluetooth (){
String message = "";
String btInput = "";
String mySsid;
if (Serial.available()) {
SerialBT.write(Serial.read());
}
if (SerialBT.available()) {
char incomingChar = SerialBT.read();
if (incomingChar != '\n'){
message += String(incomingChar);
}
else{
message = "error#erreur";
}
//Serial.write(incomingChar); // here i am able to write the data before converting it to String and split it
delay(20);
btInput += String(incomingChar);
//writeString(btInput); // writeString() is a method to print the String value
StringSplitter *splitter = new StringSplitter(btInput, '#',3);
int itemCount = splitter->getItemCount();
for(int i = 0; i < itemCount; i++){
mySsid = splitter->getItemAtIndex(1);
}
writeString(mySsid);
}
}
