I am working on serial port communication. While using BaseStream
I am writing and reading the port.
port.BaseStream.Write(dataItems, 0, dataItems.Length);
int receivedBytes = port.BaseStream.Read(buffer, 0, (int)buffer.Length);
Thread.Sleep(100);
var receiveData = BitConverter.ToString(buffer, 0, receivedBytes);
Hereafter write, I am sleeping the thread so that I will get full bytes. Is there any other way around that I can wait that all bytes are available?
Note
The last byte should be 22
. Also the above code is running in Task
named as public async Task PortHitmethod(Iterations iterations)
This is certainly a wrong way to use Stream.Read
. The correct pattern is in the documentation :
Stream s = new MemoryStream();
...
// Now read s into a byte buffer with a little padding.
byte[] bytes = new byte[s.Length + 10];
int numBytesToRead = (int)s.Length;
int numBytesRead = 0;
do
{
// Read may return anything from 0 to 10.
int n = s.Read(bytes, numBytesRead, 10);
numBytesRead += n;
numBytesToRead -= n;
} while (numBytesToRead > 0);
s.Close();
PS If you think you should use Thread.Sleep
then you can be sure you are certainly doing something wrong.
