tcp/ip socket receiver decode type-CodePudding

I have use socket TCP/IP to receive a bit stream of an FPGA board in Octave and Python.

In Octave, with [data_tcp1,len_tcp]=recv(client_tcp, 70848, MSG_WAITALL);

I received the data with dimension 70848 with datatype is uint8

Now In python, I would have the same behavior like Octave, so I tried:

data_tcp1 = client_tcp.recv(70848)# data in byte

I got the same size: 70848 but with < class byte >. There is a lot of option in python that I have tried to get the same result like Octave.

data_tcp1 = client_tcp.recv(70848).decode('ISO-8859-1')

or,

data = client_tcp.recv(70848).decode('utf-8', 'ignore')

or, data = client_tcp.recv(70848).decode()

Is there any explication in this command? What is the option should I use to obtain the same behavior like in Octave?

Thanks with best regards!

.decode method of bytes instance is used for getting str (string) based on that bytes instance. If you wish to turn each byte into number you might use list, consider following simple example

data = b"\x00\x0F\xFF"
values = list(data)
print(values)  # [0, 15, 255]
