send source route frame

[mbPejvak]

I create source route frame data structure as a string (the sequence of data explained in XBee manual) in python and I need to send it to xbee module through UART. I do not know how to do it, which class or function in XBee python library can perform it.

I'm guessing you're interested in the RouteInfoPacket type. This isn't implemented in the official API, but I wrote a patch to add it in, if it helps.

Hi @mbPejvak,

In master we already included the method get_route_to_node() to get the route to a node.

xbee = ZigBeeDevice(PORT, BAUDRATE)
xbee.open()

[...]

remote = RemoteZigBeeDevice(xbee, x64bit_addr=XBee64BitAddress.from_hex_string("1234567890ABCDEF"))

status, route = xbee.get_route_to_node(remote, timeout=5)
print("Transmit status: %s (%d)" % (status.description, status.code))
print("Route source: %s" % route[0])
print("Route destination: %s" % route[1])
print("Route hops (closest to src to closest to dst): %s"
          % " <<< ".join(map(str, route[2])))

[...]

It is also possible to register a callback to listen for received routes with add_route_received_callback() and remove it with del_route_received_callback().
The callback receives 3 parameters: source node, destination node, and the list of hops from closest to source to closest to destination:

xbee = ZigBeeDevice(PORT, BAUDRATE)
xbee.open()

[...]

def new_route_cb(src, dest, hops):
    print("Received route: %s%s%s <<< %s (hops: %d)"
          % (dest, " <<< " if hops else "", " <<< ".join(map(str, hops)),
             src, (len(hops) + 1)))

xbee.add_route_received_callback(new_route_cb)

[...]

xbee.del_route_received_callback(new_route_cb)

[...]

This support will be released in the next version. In the meantime, you can download the source code from the master branch and install the library from there (see instructions at https://github.com/digidotcom/python-xbee/blob/master/README.rst#install-from-source).

Best Regards.
