Re: Seeking WiFi-based personal alert device

There are also Bluetooth buttons or "panic buttons" that you could keep in a pocket or on a necklace or bracelet and they would trigger the nearby phone to send a message which would have redundant wifi and cellular network available. Possibly more reliable, smaller, and commercially available.

Re: Need to erase efuse bits

You can't do it but you may be able to boot a custom bootloader from internal flash that will change to external flash then load the app. However two problems: 1. d2wd internal flash runs at 1.8v so your external flash and psram should also be 1.8v 2.

Re: WIFI_STA mode for FCC co-location testing

That is unfortunate. Imagine how many transmitters in the real world are installed near each other which have never been tested together. So does it require a new fcc id or just that they are tested together? If esp32 is a station connected to an access point I don't think you can assume it is not t...
