Using pyserial to send binary data

Question

I know there has been a lot of discussion on this but I still have a question. I am trying to send hex values through pyserial to my device using pyserial

command="\x89\x45\x56"
ser.write(command)

However I keep getting an error saying string argument without encoding. Does anyone know how to solve this?

Answer 1

packet = bytearray()
packet.append(0x41)
packet.append(0x42)
packet.append(0x43)

ser.write(packet)
