My most common usage for Remote Messages is when I'm using WiFi in a public setting (coffee shops, mainly), and want to be able to have the speed and ease of a keyboard, as well as the simplicity of not constantly task-switching with my phone. Remote Messages is fantastic for this. However, it's also frequently the case that the connection is very spotty; sometimes the WiFi router's firewall outright blocks the connection. I could connect over USB, and sometimes do, but often I don't have access to a power outlet, and connecting via USB charges the phone and thus drains my laptop.
Bluetooth would seem the perfect solution here: it establishes a strong, direct connection between the computer and iPhone, without any power transfer. But I can't seem to figure out how to make the connection work. Does anyone know?
