I clearly do not understand how to drive savvycan. I have two versions on a windows 10 laptop: ?, self identifies as V203, circa April 2021 1.0.245, self identifies as V204, circa May 2021 Connecting is very problematic. I started with my Cadillac which "works". As per the documentation I started with: can log start tcpserver discard gvret-b :23 I was never able to connect with the May version. (Meanwhile, the FreeBSD version 1.0.245 port "works" as well as the Windows May executable... BTW, I'm the port *maintainer* for this!) With the older, April version I can sometimes connect but it's painful; if anything goes wrong or once it disconnects, I do not know how to reconnect, the *only* option appears to be to delete the device and add it back... In the rare cases I was able to connect (to a vehicle with an ovms module that I have started a tcpserver on, and the engine running) it *always* disconnects after N frames are received (about 125K for the Cadillac). It's like it fills up a buffer and quits. As stated, I do not understand how to drive this tool. The 2nd gen CTS has two buses: a canbus @ 500k and a single wire canbus @ 33.333k. Is it really not possible to configure the buses to *different* speeds? (And if gvret-b allows savvycan to know how many buses the network device has why doesn't it know what their respective speeds are? And why is 33.3333 missing?) Sorry for ranting about savvycan issues on the ovmsdev list but I have to believe some of you folks understand how make it do something useful. Craig
