- It's possible that the callback function is not triggered because the frames are arriving faster than the callback function can handle them. In this case, please try adding a delay or using a different synchronization mechanism to ensure that the callback function is not overwhelmed.
- Make sure that the termination character specified in the "configureCallback" function matches the actual termination character used in the serial data stream.
- If the serial port buffer becomes full, it may prevent the callback function from being triggered.
- Check that the serial port is configured correctly with the appropriate baud rate, parity, data bits, and stop bits. Incorrect settings can cause communication issues and prevent the callback function from being triggered.
configureCallback is not triggered in termination mode for the serialport communication

I try to read the output of serial port sequantially. For example , it is expected that 400 consecutive frame will come through serial port .However, after some number of frames , configureCallback is not triggered even if readline command is able to read next frame .
s = serialport("COM6",921600);
...
configureCallback(s,"terminator",@readSerialData);
function y=readSerialData(s,~)
data = readline(s) ;
end

Hi Yunus,
As per my understanding it is expected to receive 400 consecutive frames through the serial port. A callback function using the "configureCallback" function is set up in termination mode, where the callback function "readSerialData" is triggered when a termination character is received. Kindly refer to the following troubleshooting steps when encountering the issue where the "configureCallback" function is not being triggered:
Please refer to the MATLAB documentation on "configureCallback" function for more information:
I hope the suggestions helps in solving the issues you were facing.
Regards,
Maneet Bagga
