Sending AT Commands to Remote XBee using python-serial

Question

I have connected coordinator xbee to serial port of beaglebone i.e . tx and rx of beaglebone. My router's D0 pin is connected to relay. I want to remotely disable or enable the D0 pin. For that i am using python-xbee library. What I did is (my python code snippet)

myRouter='\x00\x13\xA2\x00\x40\xE4\x29\xB3'
#For Off
xbee.remote_at(dest_addr_long=myRouter,command='D0',parameter='\x04')
#For switch ON
xbee.remote_at(dest_addr_long=myRouter,command='D0',parameter='\x05')

code is working fine without error but I am not getting the output. I tried it using without beaglebone i.e. using usb explorer it works. Here is the link of example @ digi.

I am using python-xbee library. What would be the error?

Answer 1

I had the same problem as you with my beaglebone. I got success only after I specify the frame_id.

xbee.remote_at(frame_id='\x01',dest_addr_long=myRouter,command='D0',parameter='\x04')

This is my whole code that works. Note that I broadcast (address FFFF) the command.

#! /usr/bin/python
import serial
from xbee import ZigBee
import time
ser = serial.Serial('/dev/ttyO2', 9600)
xbee=ZigBee(ser)
myRouter = '\x00\x00\x00\x00\x00\x00\xFF\xFF'
xbee.remote_at(frame_id='\x01',dest_addr_long=myRouter,command='D0',parameter='\x04')
time.sleep(1)
response = xbee.wait_read_frame()
print response
