I think I know what is causing this...

This line in your python script  
` mens=bytes(payload).decode("utf-8",'ignore')`  
is creating a python bytes object

Try this code

```auto
        BOARD.led_on()
        #print("\nReceived: ")
        self.clear_irq_flags(RxDone=1)
        payload = self.read_payload(nocheck=True)
        send_mqtt_message('loramessage', str(payload))
        #print ("Receive: ")
        mens=bytes(payload).decode("utf-8",'ignore')
        mens=mens[2:-2] #to discard \x00\x00 and \x00 at the end
        print(mens)
        send_mqtt_message('loramessage', str(mens))
        BOARD.led_off()

```

I'm working on it, but as I am installing and using paho for the first time, it takes some time to solve errors, and the latest one is :

As you also guess, I have used str() lately to solve the problem in pythonshell and daemon,but face no change in answer there !

@tarahi  
I have updated the script further, I believe I have solved it, when I simulate the data it works but you should run it with python3, like "python3 scriptname.py"  
This is because python3 handles bytes/bytearray differently than python2
