On: The AT protocol is the most obtuse crock of shit

[cozzyd]

Speaking of which, does anybody know a good freestanding C library that doesn't use dynamic allocation for the Hayes AT protocol?

[sgtnoodle → cozzyd]

I've certainly had to implement AT commands in C, but within a proprietary codebase.

It's tough to do in a freestanding way given that it's a command-response protocol. It's very convenient to depend on the specific uart API that's available.
