getRX - size of incoming data

[haddock443]

Hey,

i have a problem while using this library. If i send a message to the arduino, i can only send a payload under 16 characters. As soon as I send anything above 15 characters, my String is empty.
I just want to store a message like this:
text = myLora.getRX();
and then work with it.
Am i doing something wrong?
I know this is not much information from my side, but i dont know where to start.

One thing that i noticed is: When i restart the arduino, i can receive a longer message once. After that i can only receive 15 characters.

Code:

switch(myLora.txCnf("!"))
{
case TX_SUCCESS:
{
Serial.println("TX successful and acknowledged");
break;
}
case TX_WITH_RX:
{
String received = myLora.getRx();
received = myLora.base16decode(received);
debugSerial.println("debug" + received);
delay(100);
//here i just cut the string and store the parts in global variables
int commaIndex = received.indexOf('$');
int secondCommaIndex = received.indexOf('$', commaIndex + 1);
int thirdCommaIndex = received.indexOf('$', secondCommaIndex +1);
var1 = received.substring(0, commaIndex);
var2 = received.substring(commaIndex+1, secondCommaIndex);
var3 = received.substring(secondCommaIndex + 1, thirdCommaIndex);
var3 = received.substring(thirdCommaIndex + 1); //To the end of the string

    break;
  }
  default:
  {
    Serial.println("Unknown response from TX function");
  }
}
