Any other embedded programmers or older people that remember what an AT protocol really is confused every time they see a story about Bluesky?

To be fair, anyone who's worked with cell modems knows that the other AT protocol is also an obtuse crock of shit.

Yeah, the headline even more "that's not news" when you're talking about modems. ;-)

That was the protocol I thought I was going to read a rant about by the title, and I was all ready to agree wholeheartedly with the author.

But it was a different protocol that I have no experience with. It might be a crock of shit, too, but it's hard to tell from that rant.

Interestingly, the original modem AT protocol was reasonable. Then as modems became more featureful, the protocol kept getting extended, and extended, and then I stopped using POTS modems and thought I'd never have to deal with it again.

Until I built my own cellphone discovered that not only does it live on, but it's been extended even more.

I’ve always wondered if a cable/DSL modem is an actual AT-style modem somewhere in there, but I’ve been way too scared to ask.

Some things are best left a mystery. Ignorance really can be bliss.

Not sure about DSL but cable is DOCSIS which resembles Ethernet more than telephony.

Yep, definitely right there with you on this one. Every time I think oh this will be an interesting blast from the past, followed by bah, get off my lawn...

I was just about to post that this article isn't about the AT modem commands.

With the first comment mentioning XRPC, I was even more confused, since that's the name of a protocol from around the same time period. I believe TI-RPC won that battle.

Yeah, i just wanted to comment how the AT protocol is really old, and that mobile developers decided to reuse it and add a gajillion extensions to it, so it's not really the (base) protocols fault...

We might be getting old...

This is the first time I’ve even heard of Bluesky and I’m still not sure what it is and what this new AT protocol is, so yes, was confused.

I'm happy I went straight to the comments because with yours I found out the article won't talk about the "good" old AT command protocol, which indeed, not so long ago I had to integrate with a C project for AVR chips. What else could it be? :-)

    ATZ
    OK

Yes AT is something that runs over serial links, no doubt about it
