@gcjr

a recognizable line termination such as '\n'

This will work as long as the message itself never contains newlines.

@gcjr

send the value as an ascii string with a recognizable line termination such as '\n'

instead of your recWithEndMarker(), see readBytesUntil() and it's use in the code posted in #9

@Moris526

void recvWithEndMarker() {
 static byte ndx = 0;
 char endMarker = '\n';
 char rc;
 
 
           while (Serial.available() > 0 && newData == false) {
 rc = Serial.read();

 if (rc != endMarker) {
 receivedChars[ndx] = rc;
 ndx++;
 if (ndx >= numChars) {
 ndx = numChars - 1;
 }
 }
 else {
 receivedChars[ndx] = '\0'; 
 ndx = 0;
 newData = true;
 }
 }
}
