Error while running XBee_to_UDP

I tried to run your first commit since what you've done is kind of like what I am trying to do with xbee. But I am getting this error when running the UDP side of the code.

The change that I did compared to code of yours is, my XBee device supports sending only 73 bytes at a time. So, I changed

                if 100 <= px4.in_waiting < 4095:
			data = px4.read(px4.in_waiting)
			while data:
				print('[PX4 -> XBee] {}'.format(data[:255]))
				pkt_sent = xb.send_data(GCS, data[:255])
				data = data[255:]
		elif px4.in_waiting == 4095:
			px4.reset_input_buffer()
		else:
			pass

to

                if 100 <= px4.in_waiting < 4095:
			data = px4.read(px4.in_waiting)
			while data:
				print('[PX4 -> XBee] {}'.format(data[:70]))
				pkt_sent = xb.send_data(GCS, data[:70])
				data = data[70:]
		elif px4.in_waiting == 4095:
			px4.reset_input_buffer()
		else:
			pass

Can you please help me with this.
