SDK
- the following SDK are available in github
- Standard SDK - mature solution, suitable for all kinds custom development
- NL6621_SerialNet_SDK(Wifi-UART SDK) - AT commands version, good for local LAN product development
- NL6621_SerialNet_WebServer_SDK - NL6621 WIFI to serial + WebServer SDK code, where WebServer used in SoftAP mode.
- Gizwits_SDK, Gizwits_socket_SDK, Gizwits_LED_SDK
- Other SDK: OneNet, Homekit(apple homekit), NuAgent, Yeelink, QQlink, WLANmeter
