I think it is something that would be in the Amazon code and there is no way to change it on the fauxmo side. This is a legacy integration that Amazon did back when echo was still new so that something would work with echo right away. All the newer integrations use Alexa skills in the cloud.

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. The external flash and internal flash should hav...

Move the partition table to 0xA000 the bootloader looks like it needs 36KB

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...

Is that what the test lab said? Even if they are mounted separately at a minimum distance they are considered colocated because they share a power supply? There are antenna switch gpio outputs that can be used to know when esp32 is transmitting but I don't know if there is a way to prevent esp32 fro...

Also please post when there is a resolution

Separate enclosures means not colocated imo I think you just have to instruct the user to mount them at least 10cm apart
