ENUM NL80211_PEER_MEASUREMENT_FTM_FAILURE_REASONS(9)

✨ enum nl80211_peer_measurement_ftm_failure_reasons ✨

okay bestie so this is a page from the Kernel API Manual and it's literally the whole entire tea on enum nl80211_peer_measurement_ftm_failure_reasons — like, every single reason an FTM measurement can just. not work. 💅

---

🌸 NAME 🌸

enum nl80211_peer_measurement_ftm_failure_reasons — FTM failure reasons, i.e. the group chat of why your measurement ghosted you 😭

};

🎀 Constants 🎀

okay so here's each one, no cap, each one gets its own lil moment 👑

• NL80211_PMSR_FTM_FAILURE_UNSPECIFIED — the unspecified failure, and ngl it's not used at all. it's giving placeholder energy 🙈
• NL80211_PMSR_FTM_FAILURE_NO_RESPONSE — the FTM responder literally said nothing back. silence. left on read 💀
• NL80211_PMSR_FTM_FAILURE_REJECTED — the FTM responder straight up rejected the measurement. not a vibe. 🫠
• NL80211_PMSR_FTM_FAILURE_WRONG_CHANNEL — we already know the peer is chilling on a different channel, so we can't measure. tiny caveat though: if we didn't know that, we'd try anyway and then just get no response instead. iykyk 🦋
• NL80211_PMSR_FTM_FAILURE_PEER_NOT_CAPABLE — peer can't actually do FTM. it simply does not have the range, bestie 😭
• NL80211_PMSR_FTM_FAILURE_INVALID_TIMESTAMP — the T1/T4 timestamps that came through were invalid. expired receipts, basically 🎀
• NL80211_PMSR_FTM_FAILURE_PEER_BUSY — peer reports it's busy, so you may retry later — peep NL80211_PMSR_FTM_RESP_ATTR_BUSY_RETRY_TIME for the when 👀
• NL80211_PMSR_FTM_FAILURE_BAD_CHANGED_PARAMS — the peer changed the parameters and now they're no longer supported. moving the goalposts, iconic but rude 💅

and that's the whole page bestie, every last one of them, no skipping, we do not do skipping here 💖

okay so this little icon came from ./include/uapi/linux and it's dated October 2026 — periodt, that's the whole sign-off, go touch some grass and go measure some peers 🧚‍♀️✨🌸
