您好，RTL8720DN产品请求支持  
關於這款產品，請問這個網址下是最新的固件嗎？[https://github.com/ambiot/ambd\_sdk](https://github.com/ambiot/ambd_sdk)  
在Ubuntu環境下編譯后menuconfig選單裏很多功能都不能使用。  
謝謝。

您好 @Asyulin  
開源固件都從GitHub下載，您貼的鏈接是對的。因爲 Meuconfig 并不完全開源所以想瞭解您想使用哪些功能？  
謝謝

請問你是否已經從官網下載了AMB21 Application Notes 或者 AT command 手冊？  
鏈接：[Standard SDK – Realtek IoT/Wi-Fi MCU Solutions](https://www.amebaiot.com/en/ameba-sdk-summary/)

可以先讀AN瞭解sdk結構以及如何編譯。

- AP Mode 請參考 [如何将8720DN 配置为5GHz频段下的AP #181 - #7](https://forum.amebaiot.com/t/8720dn-5ghz-ap-181/2013/7)
- UART 參考 GitHub 開源提供的範例 [https://github.com/ambiot/ambd\_sdk/tree/dev/project/realtek\_amebaD\_va0\_example/example\_sources/UART](https://github.com/ambiot/ambd_sdk/tree/dev/project/realtek_amebaD_va0_example/example_sources/UART)
- UDP 和 AP Mode 類似，采用 ATWU AT Command 運行即可。

謝謝
