Re: Help using UCLA Zigbee PHY examples updated for UHD

Hello Josh,

I realized that the error was coming from this loop in ieee802_15_4_pkt.py

try:

                self.callback =kwargs.pop('callback')

                self.threshold =kwargs.pop('threshold')

                self.chan_num=kwargs.pop('channel')

except KeyError:

pass

so I changed       self.chan_num=kwargs.pop('channel')

to                            self.chan_num=kwargs.get('channel')

It seems to be working now with

Statistics : good 0 received 0

I hope I have not messed anything else in ieee802_15_4_pkt.py.

Respectfully,

Looks like a pretty strait forward error. There is no chan_num attribute. So what class is "self" and why is it missing chan_num? How does chan_num get initialized?

Perhaps there is a command line option you are not passing, and there isnt any input checking/sanitation, so the error falls all the way through to this part of the code.
