Thanks for the logs. Really helpful.<br>

IIRC, deauth leaving means the local device has decided to leave the<br>
network. Though this doesn't make any difference for ConnMan. It's =
the<br>
same code path. Only reason code 6 is handled differently.<br>

<br>
That is what I suspected. So wpa_supplicant doesn't tell us excactly<br=

what it is doing. Suddenldy we see state transitions and we have to<br>
guess what's happending.<br>
<br>
But then we get a new message which it the disconnect reason:<br>
<br>
connmand[3595]: ../connman-1.37/src/rtnl.c:rtnl_message() NEWLINK len 72 ty=
pe 16 flags 0x0000 seq 0 pid 0<br>
connmand[3595]: ../connman-1.37/gsupplicant/supplicant.c:signal_interface_c=
hanged()<br>
connmand[3595]: ../connman-1.37/gsupplicant/supplicant.c:interface_property=
() DisconnectReason<br>
connmand[3595]: ../connman-1.37/gsupplicant/supplicant.c:signal_bss_removed=
()<br>
connmand[3595]: ../connman-1.37/gsupplicant/supplicant.c:update_network_sig=
nal() New network signal -90<br>
connmand[3595]: ../connman-1.37/plugins/wifi.c:network_removed() name purpl=
eline<br>
<br>
Could it be, whenever it works you don't get an disconnect reason<br>
after we assume wpa_supplicant is roaming?<br>
<br>
Thanks,<br>
Daniel<br>
