Earlier, it was the application code's responsibility to call the
esp_rmaker_user_mapping_endpoint_create() and esp_rmaker_user_mapping_endpoint_register()
APIs at appropriate places in Wi-Fi provisioning code to enable user node mapping
functionality. To simplify this, the logic has been moved to RainMaker Core, so that
this happens automatically.
For some reason, if you want to retain the older logic in your application code
and do not want RainMaker_core to enable this, please set the
CONFIG_ESP_RMAKER_DISABLE_USER_MAPPING_PROV config option.
If IDF version being used is 4.0, following changes will happen:
- tcpip_adapter will be used, instead of esp_netif.
- MQTT port 8883 will be used, even if 443 is chosen, because
443 requires ALPN options in MQTT, which aren't supported in IDF 4.0
MAC address is a public information and can also be sniffed easily. Creating the proof of
possession pin from that is not secure enough. Instead, a random stream of bytes is now generated
and stored in the fctry partition during claiming and that is used for the PoP.
