M300 被 planet 反應說 setting wizard 在每一次的 login 後都會跳出來很煩

希望有個選項可以把 setting wizard 關掉

M300[release/v2.02]

Products/Vendor = M300/0_GENERIC

1020

我應該開一個 wiki 來整理一下目前 setting wizard 的狀況

先把自己想要的 implement 方式整理在 wiki 上

m330[release/v0.08] 有 web ui 的需求

Vendor/Products = PI/0_PI_WIFI

m330[release/v0.08] - trigger wifi_apsta.cgi?act=status&index=0 at the beginning while 'WiFi > Client' List page opened

    trigger wifi_apsta.cgi?act=status&index=0 at the beginning while 'WiFi > Client' List page opened
    - trigger the status while user click each nav - just like the 'Refresh' button

利用最新的 m330[release/v0.08]

Vendor/Products = PI/0_PI_WIFI

準備好以下環境

測試結果

root@(none):/tmp# ./grek_20_sv &
root@(none):/tmp# ./grek_20_cl ::1 hello
Server received 5 bytes from (::1, 46385)
Response 1: HELLO

耐著性子好好的理解每一個細節
