I am wondering when espressif start advertising ESP32 as USB capable, like they did with bluetooth and after adding ble mesh ESP32 become bluetooth 5.0 certified.

In your case i would just make softAP ssid based on MAC address, so every device would have different SSID and RFID sticker on it or even better with QR code. Sure, its not best solution if you have 100 devices, but you can easy write app on smartphone which can read RFID or QR code and connect that...

I believe this function should be used https://github.com/espressif/esp-idf/blob/master/components/esp_netif/include/esp_netif.h#L477 https://docs.espressif.com/projects/esp-idf/en/stable/esp32/api-reference/network/esp_netif.html#_CPPv421esp_netif_set_ip_infoP11esp_netif_tPK19esp_netif_ip_info_t ES...

How about using HAL and small magnets?
This solution does not require additional hardware, but im not sure hal is still enabled in API.
It also is not the safest option, but you still have wifi password protected.

I know its hardware, not software solution, but maybe if you try devkit with IPEX antenna which is not connected.

Hi, i am trying to make C++ library which will help more users to build ble mesh devices with esp-idf. Library is in very early stage, like alpha or something, because ble mesh is very extensive topic with all SIG models (ble mesh v1.1 is adding a lot more models). Currently only most basic models a...

Yes, its default and can be configured in menuconfig IIRC.

Usually you want to send message to unicast or group address.

The name devkit is suggesting its for development purpose, so for our convenient we have the CP21xx. It helps to see logs when we are working on code with USB support. When you want to connect USB you can do as you said, cut USB cable and connect 2 (signals only), 3 or 4 wires to devkit and it works...

It looks like you are trying OTA before wifi connection is fully established.
