この手順は C-11AH-A2（802.11ah HAT）をセットアップして IEEE802.11ahでの広域MPP（アクセスポイント）/ MP（ブリッジ）共通のセットアップ方法です。
実行コマンドで MPP か MP を選択して起動させます。
7. MESH(MPP/MP) モードについて
セットアップは共通で、最後のコマンドで MPP か MP を選択します。
| 略称 | MPP（アクセスポイント） | MAP（アクセスポイント/中継器） | MP（中継器） |
|---|---|---|---|
| 役割 | メッシュ入口 | 中継と接続 | 中継専用 |
| 用途 | 線LAN（モデム/ルーター）と接続し、メッシュネットワーク全体を外部インターネットへ繋ぐゲートウェイ | 他のメッシュノードとデータをやり取り（バックホール）しながら、スマホなどの端末（STA）をWi-Fi接続させる | メッシュネットワーク内のデータ転送（ルーティング）のみを行い、通常はエンドユーザーの端末を直接接続させない。 |
8. SSHで接続
beatcraft提供イメージでのデフォルトのID/PWは pi/beatcraft でログイン可能です。
- MPP / MP モードで疎通を確認する
起動オプションはNRC7394 Software Package for Host mode (Linux OS)/Access Point (AP) running procedureに記載されてていますので、それに合わせてコマンドラインから起動します。
１台のみでも機能は確認できますが、疎通を試すには本機構成で組み上げた2台が必要です。
まず、SSHで接続します。
- MPP側の機器は dnsmasq を起動するために、halow用dhcp設定ファイル(halow.conf)を用意します。
sudo vi /etc/dnsmasq.d/halow.conf
interface=wlan0 bind-interfaces # DHCP レンジ（必要に応じて変更可） dhcp-range=192.168.200.10,192.168.200.100,255.255.255.0,12h # MPP の固定 IP dhcp-option=3,192.168.200.1 dhcp-option=6,192.168.200.1 # ログ log-dhcpdnsmasqを起動
sudo systemctl enable dnsmasq sudo systemctl restart dnsmasq - MP側の機器は dnsmasq を停止しておきます。
sudo systemctl stop dnsmasq sudo systemctl disable dnsmasq
