Yep, it was obsoleted before it could catch one. Sadly not so with IoT devices. Today's IoT device hardware would run HTTPS, JSON etc just fine, but there are all kinds of constrained weird protocols used, and lots of companies there have incentives to perpetuate it.
- lxgr 2y agoI wouldn't underestimate how verbose JSON over HTTPS is, compared to a binary protocol that maybe only sends a single symmetrically encrypted UDP packet per sensor status report. Some IoT devices run on CR2032 Lithium cells, and even a single order of magnitude still matters there. Network data usage can be a consideration too. Some IoT devices use satellites as a backhaul; you definitely don't want to (and in fact can't) run HTTP over something like Iridium SBD, for example.
