You can use this intermediate build. WiFi/BLE service classes are still under development but can be programmed in SDK style
Installation instructions here http://ask.winnermicro.com/article/187.html
core_w80x.zip
Attention! I don't see what users write to me here. The last entry is Put build800.zip (unzip!)
If you cannot download the main package through the board manager, Try through the Chinese mirror http://ask.winnermicro.com/article/172.html
For Linux w800build is not needed
問 求一個與w801適配的arduino環境,在這個環境下怎麼連接wifi
