Decoding binary data from serial port

should help you out I am trying communicate with a Simplebgc board via serial on my Raspberry Pi. I am writing commands to the board which seems to be working but I need help decoding the binary response. Why am I getting 23 byes when the guide seems to add to 18? I am new to both C and binary. , The response is a message which has a header:
    Start Character    1u
    Command ID         1u
    Payload Size       1u
    Header Checksum    1u
    18 bytes as defined by you.
    Body Checksum      1u

Reading Binary data from a Serial Port

wish of those help Serial communication allows to break data flow into messages by using timeout. But following KISS TNC there no such functionality is presented in this protocol.

Reading binary data with PySerial from serial port

Tag : python , By : Paulh

wish of those help It seems that PySerial (or a library that Pyserial depends on) is translating a single "0x0a" (\n) character into two characters "0x0d 0x0a"(\r\n). Both communication end-points are running on Linux, so I am not sure why someone would like to even translate those line endings at all...
Here strace indicates that sender sends only \n to ttyS0:
write(1, "M\n", 2)                      = 2
write(1, "\n", 1)                       = 1
write(1, "M\n", 2)                      = 2
write(1, "\n", 1)                       = 1

How to write binary data to serial port in C#

Any of those help I try to write some binary data to the Serial Interface with C#: , you can try this :
using System.IO.Ports;

public void TestSerialPort()
SerialPort serialPort = new SerialPort("COM1", 115200, Parity.None, 8, StopBits.One);
byte[] data = new byte[] { 1, 2, 3, 4, 5 };
serialPort.Write(data, 0, data.Length);

How to read Binary Data from Serial Port without any Encoding?

Tag : chash , By : Frank Bradley

I hope this helps . Your code is constructing a System.String instance from a byte array, which will attempt to form a valid text value from the bytes using the default encoding, whatever that happens to be on your system.
Either you need to change your SerialDataEventArgs class to use byte[] instead of string or convert the byte array to a string of hex digits using BitConverter.ToString(data) or similar. Something like:
//class SerialDataEventArgs
public class SerialDataEventArgs : EventArgs
    public string Data;
    public SerialDataEventArgs(byte dataInByteArray)
        Data = BitConverter.ToString(dataInByteArray).Replace("-", " ");

C# send data over serial port in binary mode

like below fixes the issue
Can someone please let me know what is the difference between "Binary mode" and "Not-binary mode"?
If you select this option, received characters are sent without any modifications.
Otherwise, new-line codes are converted and control characters (except TAB, LF and
CR) are stripped out.
