How does the xbee.send_data() work for HA messages?

[pablovi96]

Hi I want to send a message with an xbee3 zigbee with this python library to a Home automation device. The thing is that I dont know what the message should be, because i dont know how the function works. I have to send all the API frame from length to payload bytes as in XCTU (with theframe generator) or I can put only the bytes corresponding to the cluster ID and payload?

Thank you in advance

Hi @pablovi96,

You have to use the appropriate methods to send explicit data, see this chapter: https://xbplib.readthedocs.io/en/latest/user_doc/communicating_with_xbee_devices.html#send-and-receive-explicit-data.

Hope this helps. Regards.

Ok, this seems to work but when I send the same order as in the example the following error occurs:

Traceback (most recent call last):
  File "etc/init.d/udp.py", line 45, in <module>
    xbee.send_expl_data(remote,1,1,clid,prfid, message)

    if dest_endpoint < 0 or dest_endpoint > 255:
TypeError: unorderable types: bytes() < int()

I thougth that I could change the inputs from bytes to int but didnt work. I have put it like this also:

se=b'\x01' #source endpoint
de=b'\x01' #destination endpoint
clid=b'\x00\x06 ' #cluster id
prfid=b'\x01\x04' #profile id

any idea of how should I put the function inputs?

They must be integers:

xbee.send_expl_data(remote, 0x01, 0x01, 0x0006, 0x0104, message)

Please take a look at this example: https://github.com/digidotcom/xbee-python/blob/master/examples/communication/explicit/SendExplicitDataSample/SendExplicitDataSample.py.

Ok the problem was that I was trying this: xbee.send_expl_data(remote, 0x01, 0x01, 0x0006, 0x0104, message) and as in the example i need to put in this order: xbee.send_expl_data(remote, message, 0x01, 0x01, 0x0006, 0x0104)

Thank you very much!
