====== Digi.Xbee library:======

Usage of digi.xbee library for wireless data communication:
Source: [[https://xbplib.readthedocs.io/en/latest/getting_started_with_xbee_python_library.html]]
<code bash Install > pip3 install digi-xbee </code>
<code bash fix install error> pip3 install --upgrade setuptools </code>

===== Typical required imports: =====
<code python imports>
import time
import sys
from digi.xbee.devices import XBeeDevice, RemoteZigBeeDevice, XBee64BitAddress, ZigBeeDevice, RemoteXBeeDevice, XBeeMessage, IOMode
from digi.xbee.io import IOLine
from digi.xbee.packets.common import TransmitStatusPacket
</code>

===== Typical instantiation of local device: =====
<code python init local devices>
# instantiate XbeeDevice object:
#device = XBeeDevice("/dev/ttyS2", 9600)
device = ZigBeeDevice("/dev/ttyS2", 9600)
#device = ZigBeeDevice("COM13", 9600)
device.set_sync_ops_timeout(5)
device.open()
</code>

===== Typical instantiation of a remote device: =====
<code python init remote-devices>
# Instantiate a remote XBee device object.
remote_device = RemoteXBeeDevice(device, XBee64BitAddress.from_hex_string("0013A200xxxxxxxx"))
</code>

===== remote pin control: =====
<code python set IO>
remote_device.set_io_configuration(IOLine.DIO11_PWM1, IOMode.DIGITAL_OUT_HIGH)
</code>
===== Typical serial data transmission: =====
  * Send text to remote receiver 
  * receive text back from remote receiver
<code python serial data communication>
# Send data using the remote object.
#state = device.send_data(remote_device, "Hello XBee!")
sendID = 0
while(True):
    if(sendID == 3):
        sendID = 0
    else:
        sendID += 1

    #h = hex(sendID)
    #v = ("\xFF".encode('Latin-1'))
    #state = device.send_data(remote_device, v)

    state = device.send_data(remote_device, chr(sendID))

    if(state != None):
        print(state.transmit_status)

    time.sleep(0.2)

    # Read data.
    xbee_message = device.read_data()
    if(xbee_message != None):
        remote_device = xbee_message.remote_device
        data = xbee_message.data
        is_broadcast = xbee_message.is_broadcast
        timestamp = xbee_message.timestamp

        print(str(data.decode()))
    else:
        print("No return message")

</code>

===== At end of program: =====
<code python close port>
device.close()
</code>
