I've been using the OptoMMP Driver for a while now (with awesome success) for a bunch of communication we're doing. We're looking at possibly using a SoftPAC for a customer though, and, although the primary functions that we use (Scratchpad read and write) work great, I noted that one particular function does not. (There may be more, but I haven't needed them!)
The command is OptoMMP2.OptoMMP.ReadBrainDiagnosticInformation which I use to monitor a bunch of stuff. On my S1 it works as expected with SoftPAC controller it returns an empty structure.
Admittedly I could re-write this to directly grab the information that I'm looking for (with a direct read of an address), but I'm curious if this is a known bug and therefore should wait?
