RTL8720DN, RTL8710B, RTL8710BX Compatibility with OpenBeken?

✨ The discussion centers on the compatibility and support of Realtek RTL8720DN, RTL8710B, and RTL8710BX chips with the OpenBeken firmware and SDK. The RTL8720CF-based modules (e.g., BW15, WBR3) are confirmed to be supported by the AmebaZ2 family SDK and OpenBeken ports, with functional WiFi, GPIO, flash configuration, OTA, UART, and basic peripherals. However, RTL8710BX and RTL8710B (AmebaZ family) present challenges such as WiFi initialization freezes, memory management issues, and incomplete SDK support, including lack of static IP and WiFi scanning. OTA updates are functional but have occasional reboot issues, especially on RTL8710B. PWM support is mostly stable after fixes, while MQTT required patching due to missing authorization code in the Realtek LWIP stack. Power-saving modes and sensor drivers (DHT11, DS18B20) have been tested with varying success across platforms. Flashing RTL modules requires specific UART converters (e.g., CH340G) and careful wiring; some modules need manual pin pulls and special flashing tools like AmebaZ2 PGTool. TuyaMCU and energy metering ICs (BL0937, BL0942) support is under active development and testing, with UART and GPIO interrupt methods used. Memory partitioning for configuration, LittleFS, and Tuya config extraction is being optimized to avoid overwriting user data. Static IP implementation required workarounds due to sscanf inconsistencies on RTL and related platforms. A UART-to-TCP bridge driver has been developed for some modules. Overall, RTL8720CF modules have good OpenBeken support, RTL8710B is progressing but unstable, and RTL8710BX remains problematic. The community is actively testing, fixing, and improving support for these Realtek chips within OpenBeken and related tools.
