<html> <head> <meta http-equiv="content-type" content="text/html; charset=UTF-8"> </head> <body> Hello, I've first posted on stackoverflow but couldn't get any usefull answer (gomenasai 😅) I'm trying to start a task when bluetooth is ready on a raspi (running raspbian 10 - buster) with systemd. I've added the file /etc/systemd/system/my.service with this content <blockquote> <pre><code>[Unit] After=bluetooth.target Requires=bluetooth.target [Service] Type=idle ExecStart=/root/my.sh [Install] WantedBy=multi-user.target </code></pre> </blockquote> Then I used the sudo systemctl enable my.service command, and rebooted. After reboot I look at services launch order with <code>systemd-analyse plot</code>, and it turns out that my service starts after bluetooth.target as expected. But bluetooth.target gets started very early (attachment bt1.svg). And <code>systemctl show bluetooth.target</code> tells me 'After=bluetooth.service' so why is bluetooth.target point is reached way before bluetooth.service? I precise that if I use <blockquote> <pre><code>[Unit] After=bluetooth.service Requires=bluetooth.service</code></pre> </blockquote> it's also weird: my service is started early, way before bluetooth.service and bluetooth.target (which as expected is activated rigth after bluetoothd is ready, attachment bt2.svg). Could you tell me what's wrong? Sincerely <code></code> <div class="moz-signature">-- <meta http-equiv="content-type" content="text/html; charset=UTF-8"> <title></title> Gildas Bayard Ingénieur de Recherche Responsable Sécurité des Systèmes d'Informations Coordonnateur pour la Protection du Potentiel Scientifique et Technique Télétravail le mercredi Laboratoire HEUDIASYC - UMR CNRS 7253 UTC Centre de Recherches de Royallieu BP 20529 - 60205 Compiègne Cedex Tél. 03 44 23 46 71 </div> </body> </html>
