WiFi | 软件：茶鄧淺談 高通 Wi-Fi EasyMesh 初始設定Sample 1

關鍵字 :EasyMeshSPF12.xQualcommMLOSample Configuration

前言:

高通支持Wi-Fi EasyMesh功能。將裝置分為CAP以及RE兩個角色。透過IEEE 1905協議，彼此交互傳遞訊息。隨著WiFi6、WiFi7規格的進程，EasyMesh也需要對6G Band以及MLO等功能進行支持。初始設定也有些許的修改。列出Miami-RDP468/RDP441 MLO[BH: 5+6; FH: 5+6] 的設定供大家參考。

範例 CAP:

Onboarding :

使用WPS功能做Onboarding。 直接按WPS button或用WPS command模擬按WPS button的動作

==============

env -i ACTION="pressed" BUTTON="wps"  /sbin/hotplug-call button; sleep 1; env -i ACTION="released" BUTTON="wps"  /sbin/hotplug-call button

解析:

  1. 首先使用/usr/sbin/wifimeshconfig map 指令，將程式集鏈結到mesh。
  2. 設定network。 CAP是路由器，RE是Repeater
  3. 設定wireless。確保6G band可以使用

uci set wireless.qcawifi.ema_ap_support_wps_in_6ghz=1

uci set wireless.wifi2.band='3'

使用mlo的介面

uci set wireless.wifi1.mloenabled=1

uci set wireless.wifi2.mloenabled=1

  1. 設定ezmesh，基本都是預設值，不需要更改
  2. 設定ezlbd﹑，基本都是預設值，不需要更改
  3. 設定repacd， repacd是最主要的啟動程序。會自動去修改wireless中的設定，比如ssid, password等等。
  4. 設定wpslcd，這個設定是針對clone行為的參數，所以BSS的數量很重要要特別設定 uci set wsplcd.config.MapMaxBss=8
  5. 最後/etc/init.d/repacd start 用來當作mesh的entry point。進行一系列的設定跟初始化。

結論:

高通Wi-Fi EasyMesh，透過repacd來實現自動設定。在uci中做一些關鍵性的設定。腳本會自行對wireless區動作設置，雖然uci的設定看起來很複雜，但是執行起來也是很直觀的。畢竟高通已經提供了相當完整的腳本應用。

提問:

1.使用mesh與不使用mesh的差異?

Ans: 使用mesh的時候 wireless會被repacd腳本做重新配置，所以不可以自己去建立uci wireless 的內容。

2.為什麼要執行/usr/sbin/wifimeshconfig map?

Ans: 過去高通有SON的功能，使用的hyd等程式相對於ezmesh是相同的功能。這個指令就是做SON, MAP的切換。

3.Wi-Fi 6G的使用一定要啟動MLO嗎?

Ans: MLO是WiFi 7的規格之一，高通的Easymesh同樣可以支持WiFi 6E 所以MLO並不是一定要啟動的。

4.ezmsh、wsplcd、ezlbd這些程式的功能?

Ans: ezmesh : 是建立mesh topology的主程式。 ezlbd : 主要實現wifi load balance的功能。 wsplcd:  住要實現wifi clone的功能。

5.一定要使用WPS來做Onboarding嗎?

Ans: WPS，DDP都是使用來Onboarding的方法。
