The error I get is that struct.unpack should be passed a string of
at least size 2
That means that the code is being handed a string of length < 2 bytes.
Not getting the bug after your changes was probably coincidental. I've
seen this happen on occasion when a packet is receive erroneously and
the header is corrupted. The framer state machine looks for the repeated
packet length after correlating with the access code. What's probably
happening is the header is being read in as double 0's, so it passes on
a packet of length zero. When unpacking, Python is throwing an exception.
The right thing to do here is catch the exception and mark it as a
missed packet.
