Anyone have experience scaling with more than 256 devices?
I use MQTTS at work and for my own projects. It is a very thin protocol (low code footprint), especially combined with Wi-Fi where those stacks typically eat up most of your MCU's flash if you're using a single-chip solution with TLS. I've used it on a max of 256 devices on a single BSSID, but I would be curious to know how it scales.
EDIT: Specifically, when all devices are subbed to a noisy channel. In some cases we had to stagger pub with random jitter to prevent both Wi-Fi and edge processing issues.
