I have figured it out. Use webseriallite library. Also the msgCallback() function has been replaced with onMessage(). Just swap the words. Webseriallite still uses regular webserial commands. After the change I have had no issues.

Compilation error: ‘class WebSerialClass’ has no member named ‘msgCallback’

I am using the 2.0.7 version of webserial.
I have another sketch that used to work fine but now gives me the same error.
Is it possible when the library updated that something has changed?

I was able to change the port on which either the server you want, or webserial, when instantiating the server. Of course, you will have to change the name of the server from the examples, and any references to them in your code.

Example:
AsyncWebServer serial_server(80);
AsyncWebServer ota_server(81);

I have webserial running on port 80, and then I start the OTA server on port 81. I can assume any number of servers running all on different ports.

Hi.
Save the result of the currentTime – previousTime in a variable and convert it to a string before printing it using webserial.
Regards,
Sara

Hi Sara – I noticed that when I changed back WebSerial on one line to Serial.Print, the code compiled fine. The previousTime became unrecognised when I used WebSerial.Print….

Here is the error message:-src\main.cpp: In function ‘void loop()’:
src\main.cpp:180:50: error: call of overloaded ‘println(long unsigned int)’ is ambiguous
WebSerial.println (currentTime – previousTime);
^
And here is the block of code, which now compiles when I change one specific reference from WebSerial to Serial.

Any ideas what is happening here?

if (systemState != priorSystemState)
{
WebSerial.print (F(“States – FROM:- “));
WebSerial.print (messages[priorSystemState]);
WebSerial.print (F(” TO -> “));
WebSerial.println (messages[systemState]);
WebSerial.print (F(“doorSensorStatus:- “));
WebSerial.println (doorSensorStatus);
WebSerial.print (F(“masterSwitchStatus:- “));
WebSerial.println (masterSwitchStatus);
WebSerial.print (F(“Current Time:- “));
WebSerial.print (currentHour);
WebSerial.print (F(“H:”));
WebSerial.print (currentMin);
WebSerial.print (F(“m:”));
WebSerial.print (currentSecs);
WebSerial.println (F(“s:”));
WebSerial.print (F(“PriorPIR / CurrentPIR – INSIDE “));
WebSerial.print (priorpIRiNStatus);
WebSerial.print (F(” / “));
WebSerial.println (pIRiNStatus);
WebSerial.print (F(“PriorPIR / CurrentPIR – OUTSIDE “));
WebSerial.print (priorpIRoUTStatus);
WebSerial.print (F(” / “));
WebSerial.println (pIRoUTStatus);
WebSerial.print (F(“HBridge 1 / HBridge 2:- “));
WebSerial.print (digitalRead(HBridge1));
WebSerial.print (F(” / “));
WebSerial.println (digitalRead(HBridge2));
WebSerial.print (F(“Flap Elapsed Time: “));
Serial.println (currentTime – previousTime);
WebSerial.print(F(“motorEnable Pin: “));
WebSerial.println(digitalRead(motorEnable));
WebSerial.println (F(“***********************”));
