Iron Python Error: expected <type 'bytes'> or bytearray, got <type 'str'> for Serial comm

问题

Unable to understand this: When I run using python shell it works but doesn't: when invoked using Iron python. It throws above error

C#:

scriptEngine.ExecuteFile(path);
var testFn = scriptScope.GetVariable("InputSelection");
var stream = new MemoryStream();
scriptEngine.Runtime.IO.SetOutput(stream, Encoding.Default);
scriptEngine.Operations.Invoke(testFn);

Python:

def send_data(message,check):
    if message:
        ser.write(message.encode('utf-8'))

    time.sleep(2)
    response = ser.read(1024)

def InputSelection():
    send_data("Hello","Hello")

Looks like you're hitting a bug in IronPython. In the meantime you can workaround it by using:

ser.write(bytes(message.encode('utf-8')))
