at the bottom of the arduino.cc page it says " Corrections, suggestions, and new documentation should be posted to the [Forum]"
which takes me to these forums which have no category for documentation. so i guessed this category "website/community".
then the forum says to use github to report issues - but has no link to github nor an indication if this means regarding documentation problems or otherwise.
but anyway. the link is broken. This is the borken link:
Apparently "Standard Services" is not a standard piece of bluetooth jargon because searching for that phrase on the web does not provide any kind of basic definition or list.
Unfortunately, this particular content is not hosted in a GitHub repository, nor in a manner that allows direct collaboration from the community. I actually don't even have access to this content.
