Made some progress tonight. I'm not sure why but logCommand() is very touchy. If I even reference &Serial1 it stops streaming. If I do not provide a heartbeat, (with the btRateLimit enabled) it won't stream.
If I remove btRateLimit completely and ensure I have a filter that removes the bulk of the noise, it works fine.
