Ahhh I wanted to use the esp32, and thus the esp-at for some specific stuff, but I'm a bit clueless about what else is available and what I'd be missing. What are the more stone agey parts of it?
An obnoxious mountain of binary blobs, no 5 GHz, no WPA3, and if you plan on using Bluetooth, you're gonna have to re-flash the ESP every time you want to add a new GATT attribute.
