Help reading data from serial RS485

[korenron]

so what do I need to do?
what do I need to to make it work ?
change something in the send code?
the sender is using python2 and the receiver use python3

now I'm sending only this:

send.write(bytes('test\r\n'))

and I get this

b'\xbe\x1b\xff'
b'\xbb\x1b\xfe'
b'\xbb\x1b\xfe'
b'\xbb\x1b\xfe'
b'\xbb\x1e\xfe'
b'\xbb\x1b\xfe'
b';\x1b\xff'
b'\xbe\x1b\xff'
b';\x1a\xfe'
b'\xbb\x1b\xfe'
b'\xbb\x1b\xfe'

so I'm getting bytes - but how do I get from this the work 'test'? (which I have sent )?

I assume it's something very easy to do ?

Thanks,
