Development / Changes in Networking (current version of Bridgecommand)
« on: September 19, 2018, 01:15:14 PM »
Firstly this is a thoroughly impressive (and comprehensive) simulator. I was playing around with its interface and hoping to make my own controller for it, when I noticed a forum member named Huckleberry had tried something similar and seemingly got it working really easily.

I opened up a listening port in Python (UDP on port 18304) and started the newest BC (ver 5.3 as of this writing) looking for the message described in the networking page. What I receive on there is fairly indecipherable, however it does look consistent between restarts of BC.

For instance - here is one such received string

b'\x8f\xff\x13\xe4\x82\xff\x00\x01\x00\x00\xff\xff\x00\x00\x05x\x00\x00\x10\x00\x00\x00\x00\x02\x00\x00\x1c \x00\x00\x07\x08\x00\x00\x13\x88\x00\x00\x00\x02\x00\x00\x00\x02\x9f4R\xd3\x00\x00\x00\x00'

I assumed it was some encoding/decoding error on my end - but I cant seem to find a codec which would change any of those byte to BC.

I tried running netcat on the same port and got essentially the same string (without seeing the hex representations of course)

I then downloaded an older version (4.6) and the strings immediately looked like what I expected from the documentation.
(  BC1289041152,0.0,1289041152#1369.59,4314.28,180.0,0.0,etc...) - essentially integer followed by the BC string.

Is there another encoding or perhaps something I've overlooked in the new version to get the right string there ?

Thanks very much for developing such an amazing piece of software and for all your help !
