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
The common code for WS2812 RGB LED has been moved to a component ws2812_led.
The WS2812 LED is available only on ESP32-S2-Saola-1 boards and hence
it will be enabled only if IDF target is set to ESP32S2. It can
be disabled by disabling the CONFIG_WS2812_LED_ENABLE config option.
led_strip component files have also been moved to ws2812_led
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.
- APIs and data structures changed to a more object oriented approach.
- Some internal files split into multiple files to separate out functionality
of node, device and parameter.
- A new doc file CHANGES.md added to help understand the changes.
- Modified all the examples as per these changes in the RainMaker APIs.
switch: Used the default OTA Server certificate to demonstrate simplest usage.
led_light: Added OTA calls that demonstrate using own server certificate.
