And it can be sent at any time? multiple times? Do we expect the backend to handle any endianess? Thanks for the feedback. I tried to write the docs to the same level of detail of the other messages, but agree that we should start to make an effort to have more elaborate documentation. I'll address your questions on the spec and send a v2. I also noticed the "id" above (on the doc) should be 23. Thanks, Felipe
