AT Protocol Overview
- blueflow 4y agoThis is not to be confused with the Hayes command set with is also called "AT" and is still used by mobile data modems.
- OJFord 4y agoBut of course, that is confusing. This is the 'Social networking technology created by Bluesky'.

- r721 4y agoEvery HN discussion about this protocol contains a huge subthread about this name collision :(
- techdragon 4y agoBecause its is a really stupid thing to name a protocol... Given how there is a genuinely historic, still actively used protocol with the same name. About the only thing I can think of that might be stupider to name a newly created protocol today would be some variation of "TCP" or "IP". The "AT Protocol", or more properly the Hayes AT Command set provided the fertile ground for two decades of modem compatibility work and eventual standards and helped fuel the very earliest growth of general public access to the internet. While not technically the exact same command set, the GSM standards for sending SMS messages over all cell networks, use what is effectively a derivative of the AT Command set, and to this day you can still find similar AT style "derived" commands in the heart of devices using cellular modems as part of the software that initialises a data connection out to the internet via a modern 4G or 5G modem. It's just such such a spectacularly bad name for anything new to do with communication of any kind.
- VectorLock 4y agoI clicked on it expecting it to be exactly that.
- lucb1e 4y agoOkay so this is some protocol reference document. What is one supposed to use this for / what problem does it solve?
- mdaniel 4y agoI'm guessing the previous thread (https://news.ycombinator.com/item?id=33252108 https://news.ycombinator.com/item?id=33252108) will offer more insight, but the short version is "nothing" because it's just a spec

Its future under Musk’s pared-down company looks shaky. >Bluesky was formally organized as a public benefit LLC led by software engineer Jay Graber in late 2021, and as of April, it had received $13 million from Twitter. https://www.theverge.com/2022/10/29/23428241/elon-musk-twitter-bluesky-decentralized-social-networking-future https://www.theverge.com/2022/10/29/23428241/elon-musk-twitt...
- grishka 4y agoSo they saw ActivityPub and invented their protocol that achieves the same thing but does it in a much more convoluted way.
- strangus 4y agoNot the AT I was expecting.
- vilkkala 4y agoHacking with an SMS controlled HVAC system and I clicked the link with probably similar expectations as you.
