I’m just learning there’s a whole class of low computing power devices that can’t connect to WiFi without a phone detecting and onboarding them. How does this work? Does the device broadcast a “help me connect” signal that the app detects and then sets an IP address?

The common thing is that the device creates its own WiFi network that the phone connects to and then sends it the ssid and pw it needs. Which is a shame given how zeroconf was designed to solve this problem 20 years ago.

Are they nominally Bluetooth3+HS?
This is a version of BT that uses BT discovery (ie can find your phone) but can then switch to WiFi for bulk data transfer.

No but this is cool

I have a security camera where their phone app sends a series of audio tones that the camera's microphone picks up to set the wifi network.
