The Arduino ESP32 version 2.0.2 based on the ESP-IDF v4.4-beta1 includes mainly peripheral APIs refactoring, improvements and bug fixes.
Here is a summary of the major changes.
Peripherals refactored to use ESP-IDF APIs:
- Timer
- LedC
- DAC
- RMT
- SigmaDelta
Improvements:
- Boards added and some updated (TTGO-LoRa32, Adafruit boards, DPU ESP32...)
- Added Sonoff DUALR3 support with RainMaker example
- GPIO defines for C3 added
- Github CLI workflow updates
- Added support to change LoopTask Stack size
- New Documentation added (USB, GPIO, Arduino as component)
Bugfixes:
- I2C Clock stretching
- SD card status check
- Baudrate with CPU Freq < 80MHz
- SetCpuFrequencyMhz() changes Serial bauds if frequency<80Mhz
- Lib Builder compiling errors
- WiFiSecureClient memory leaks when SSL/TLS connection fails
- Change default WiFi STA encryption to WIFI_AUTH_WPA2_PSK
- Forces UART Flush() to wait until all bits are sent
