Error reported by Wireshark - do I need to import some lua packages maybe? #2

Hi Roddy. Thanks very much for providing these invaluable tools.

With the latest Wireshark on Win64 (V4.4.0) and your latest SWP-08 dissector, I get this error: Lua Error: ...ogram Files\Wireshark\plugins\probel_swp08_dissector.lua:209: attempt to index a nil value (global 'bit32')

I wonder if perhaps I need to add Lua packages like bit32 to my Wireshark install somehow?

Thanks for any suggestions,

Maurice Snell

Good catch - Wireshark 4.4 uses Lua 5.4 which no longer includes the bit32 library. I'll post an update shortly.

Glad to hear you're finding these useful.

Now resolved, using the bitop library which is present in all Wireshark versions.

I've also fixed a bug where SW-P-08 messages crossing a packet boundary weren't reassembled correctly.
