[yocto] connman and dhcp

[Mauro Ziliani]

Hi all.

I'm working with connmanctl, a dongle wifi EDIMAX EW-7881UN with 
imx6dlsabresd, yocto Krogoth.


By connmanctl I can authenticate the pc, and set the connection for dhcp 
ip assignment.

The device is recognize as wlan0.


connmanctl>  connect wifi_XXXXXX

OK


After I try to switch to manual ip, and it works . The new setup is 
active after some second.

connmanctl> config wifi_XXXXXX --ipv4 manual ip netmask gw


Then I try to return with dhcp assignment

connmanctl> config wifi_XXXXXX --ipv4 dhcp.


After this sequence when I return to dhcp option, The ip isn't renewed 
anymore

I stay with the ip 169.254.86.142


It seems that when I come back to dhcp setup, the dhcp server doens't 
answer, or connman doesn't send dhcp request.


Any idea?
