Xbee in API mode - how do I read a remote Xbee pin

Hi guys,

I have 2 x Xbee configured in ZigBee API mode and using the Python API wrapper to talk to the remote Xbee plugged into an Arduino Uno.

I can successfully send frames to the remote Xbee via a Python CGI script to turn an LED on and off but I don't know how to 'read' the Xbee pin state via the API.

Has anyone played round with the Python Xbee API handler ??

Cheers

Got a link to the python stuff that you want to share?

Sure !

As I said, you have to have the XBee's in API mode for this to work. I should have also added I am using series 2 XBee radios.

Cheers.

What does your sending script look like?

What is running on the arduino ? Nothing yet, I am simply trying to get the Xbee to switch one of its digital pins high / low which I will then use to trigger the arduino on on of its digital pins.

I have since found out that it is NOT so easy to read digital I/O state on the XBees....

# Receive samples from the remote device

        self._set_send_samples(True)

        

        while True:

            packet = self.hw.wait_read_frame()

            

            if 'adc-0' in packet['samples'][0]:

                # Stop receiving samples from the remote device

                self._set_send_samples(False)

                return packet['samples'][0]['adc-0'] > XBeeAlarm.DETECT_THRESH

This came from Paul W the creator of the Xbee Python API wrapper. I think I might rethink my requirement to gain pin status feedback in my project.

This is from the example alarm.py (GitHub - niolabs/python-xbee: Python tools for working with XBee radios) at around line 186.
