ENUM NL80211_CQM_RSSI_THRESHOLD_EVENT(9)

💖 NAME 💖

enum nl80211_cqm_rssi_threshold_event — the RSSI threshold event, bestie. Yes that's the whole vibe. It's the enum that tells you a signal-strength threshold got crossed (or, spoiler, one reserved member that literally never shows up).

So you're in the Kernel API Manual, the enum nl8021...eshold_event(9) page, and honestly? It's a short one. A little snack. A palate cleanser between the giant wireless enums. Enjoy it while it lasts 🍓

✨ SYNOPSIS ✨

enum nl80211_cqm_rssi_threshold_event {
    NL80211_CQM_RSSI_THRESHOLD_EVENT_LOW ,
    NL80211_CQM_RSSI_THRESHOLD_EVENT_HIGH ,
    NL80211_CQM_RSSI_BEACON_LOSS_EVENT

};

That's it. That's the whole enum. Three members, one of which is a decorative ghost 👻 (more on that below).

---

🎀 Constants 🎀

Okay so here are the members, one by one, no skips, no cap:

• NL80211_CQM_RSSI_THRESHOLD_EVENT_LOW — the RSSI level dropped below the threshold you configured. The signal said "I'm lowkey not doing great" 📉
• NL80211_CQM_RSSI_THRESHOLD_EVENT_HIGH — the RSSI level is higher than the configured threshold. Glow up, signal. We love to see it 📈
• NL80211_CQM_RSSI_BEACON_LOSS_EVENT — and this one? reserved, never sent. Periodt. It's in the enum for Reasons™, but nothing will ever actually fire it at you. If you're waiting for this event, bestie, you're gonna be waiting forever 💀

Fr fr: don't build your whole event-handling logic around NL80211_CQM_RSSI_BEACON_LOSS_EVENT arriving, because the manpage is extremely clear that it's reserved and never sent. That's not a vibe, that's just the facts 🫶
