thanks for the prompt fix, Paul,
below is a frame printed from a print statement i put in base.py to view the
unpacking. it does echo the same as in the x-ctu terminal. the correct 64-bit
address is in the frame & the len is correct, 0x26. [00 13 A2 00 40 2C 4F A8]
7E 00 26 82 00 13 A2 00 40 2C 4F A8 32 00 06 22 00 00 C2 00 97 00 21 00 2F 00
45 00 37 00 D1 00 99 00 85 00 7B 00 18 00 28 3C
however, the source_addr_long': '\x00\x13\xa2\x00@,O\xa8' is missing 3 bytes in
its printout
{'source_addr_long': '\x00\x13\xa2\x00@,O\xa8', 'rssi': '2', 'id':
'rx_io_data_long_addr', 'samples': [{'adc-0': 194, 'adc-4': 151}, {'adc-0': 33,
'adc-4': 47}, {'adc-0': 69, 'adc-4': 55}, {'adc-0': 209, 'adc-4': 153},
{'adc-0': 133, 'adc-4': 123}, {'adc-0': 24, 'adc-4': 40}], 'options': '\x00'}
i see in the struct, "source_addr_longit", is listed for a size of '8', though
upon returning the packet, it appears to get truncated or something. the "@"
char in the 4th byte of the "source_addr_longit", is that supposed to be there?
just something i noticed and this may be by design as i'm quite new to python.

That looks correct to me. If you take a close look at the 'source_addr_long'
string, you will see 4 raw bytes '\x00\x13\xa2\x00', followed by the @ sign, a
comma, and a capital O. Finally, there is the last raw byte '\xa8', for a total
of 8.
When representing string of binary characters, you will tend to see random real
characters, such as these, pop up whenever a byte happens to be of equivalent
value to a non-whitespace ASCII character.
For example, in the interpreter:
>>> '\x61'
'a'
>>> '\x00'
'\x00'
>>> '\x40'
'@'
Also, to verify that I'm sane:
>>> print len('\x00\x13\xa2\x00@,O\xa8')
8

thanks for pointing that out. indeed that is correct. i [see] it now & i didn't
investigate far enough.
you are still sane, and i'm still on the edge. ;-)
thanks
Bill
