Binary data with pyserial(python serial port)

Question

serial.write() method in pyserial seems to only send string data. I have arrays like [0xc0,0x04,0x00] and want to be able to send/receive them via the serial port? Are there any

Answer 1

An alternative method, without using the array module:

def a2s(arr):
    """ Array of integer byte values --> binary string
    """
    return ''.join(chr(b) for b in arr)
