Zdravím, měl bych dotaz. Chtěl bych docílit aby se raspberry pi 3B+ (dále jen rpi) samo po startu připojilo k wifi pokud je dostupná.
Na většině distribucí co jsem používal stačilo informace o síti zapsat do /etc/wpa_supplicant/wpa_supplicant.conf a povolit supplicnat po startu, zde to ale nefunguje. Zkoušeno na čistém aktualizovaném Archlinuxu pro architekturu armv7.
V případě že v systemd povolím wpa_supplicant.service tak poté mi to po restartu do logu vypíše
úno 25 22:29:58 alarmpi systemd[1]: Starting WPA supplicant...
úno 25 22:29:58 alarmpi wpa_supplicant[272]: Successfully initialized wpa_supplicant
úno 25 22:29:58 alarmpi systemd[1]: Started WPA supplicant.Ale rozhraní je pořád down.
Pokud se pokusím připojit pomocí příkazu: wpa_supplicant -B -Dnl80211 -c/etc/wpa_supplicant/wpa_supplicant.conf -iwlan0 -d
tak se připojím a po zavolání dhcpcd dostanu i IP adresu.
V logu dostanu toto
wpa_supplicant v2.6

Ale je to jen laický odhad. Vím že si můžu udělat vlastní skript co se mi pustí po naběhnutí systemu a připojí se k wifi protože poté už wpa_supplicant funguje, ale já hledám nějaké čistější řešení.
Za každou radu díky

Tak jsem ten problem vyřešil. Zatímco v ostatních distribucích je pro připojení spustit wpa_supplicant.service tak v archlinuxu pokud potřebujete např. připojit wlan0 k wifi tak je potřeba spustit službu wpa_supplicant@wlan0.service. Tato služba se spustí už správně - tedy po inicializaci síťové karty kernelem a připojení proběhne správně.
