Configure WiFi

• Scan for access points (run multiple times for more complete scan):

    # connmanctl scan wifi
    Scan completed for wifi
  

• Display access points discovered:

    # connmanctl services

• Displays details on the AP of interest:

    # connmanctl services wifi_009e959b585c_32426c756557694669_managed_psk
    /net/connman/service/wifi_009e959b585c_32426c756557694669_managed_psk
      Type = wifi
      Security = [ psk ]
      State = idle
      Strength = 63
      Favorite = False
      Immutable = False
      AutoConnect = False
      Name = 2BlueWiFi
      Ethernet = [ Method=auto, Interface=wlan0, Address=00:9E:95:9B:58:5C, MTU=1500 ]
      IPv4 = [  ]
      IPv4.Configuration = [ Method=dhcp ]
      IPv6 = [  ]
      IPv6.Configuration = [ Method=auto, Privacy=disabled ]
      Nameservers = [  ]
      Nameservers.Configuration = [  ]
      Timeservers = [  ]
      Timeservers.Configuration = [  ]
      Domains = [  ]
      Domains.Configuration = [  ]
      Proxy = [  ]
      Proxy.Configuration = [  ]
      Provider = [  ]
  

• Write config file for connecting to secure AP:

    # cat << EOF > /var/lib/connman/<SSID>-psk.config
    [service_wifi_<hash>_managed_psk]
    Type = wifi
    Name = <SSID>
    Passphrase = <passphrase>
    EOF
  

  • Should be automatically re-read without needing to restart connman.
  • Verify this worked correctly by re-running connmanctl services and observe Immutable, AutoConnect and Favorite are set to true.

• Connect to the new secure AP:

    # connmanctl connect wifi_009e959b585c_32426c756557694669_managed_psk
  

  • Verify correct operation by running connmanctl services and observe the local interface address as well as DNS. Also can check ip addr ls and cat /etc/resolv.conf

Comments / Issues

• WiFi driver + connman-1.17 + beaglebone appears to be buggy with connmanctl disable/enable
• Connmanctl connect seems buggy, potential it calls enable?
