The linked blueferry doc is excellent. Back in 2020, inspired by a comment on HN, I looked into writing a proxy to send and receive iMessages on Linux through an iPhone connected with Bluetooth Message Access Profile (MAP). I was able to send and receive messages, but I ran into the problem mentioned in the doc in the "Group metadata side channel" section: the bMessages in the inbox included the message originator, but didn't include the recipients, even though the MAP standard says that it "shall" be included (see page 22). I didn't know about ANCS, so it didn't occur to me to use that channel, and without any way to tell what context a message was sent in, I couldn't do threading, so I decided it wasn't worth pursuing.

The group messages were the biggest problem, and that's what made me give up, but there were some other issues:

- Shared links showed up as "Website: Short description (example.com)" and didn't include the URL

- Images weren't shown at all

I might take a look and see how blueferry handled those limitations.
