Re: Problem with reconnect to WiFi
by Tomasz Bursztyka
Ok, it's been a while since I read connman logs, but it seems you have
ethernet cable plugged
in (and it autoconnects at boot time), right?
That would explain why connman does not connect wifi: it's already
connected through ethernet.

Waiting time to restart DHCP after receiving DHCPNAK
by Saurav Babu
Hi All,
When connman's gdhcp client receives DHCPNAK message then it restarts DHCP
after 3sec. Is there any specific reason for this delay of 3sec?
In RFC 2131 "If the client receives a DHCPNAK message, it cannot
reuse its remembered network address. It must instead request a new
address by restarting the configuration process, this time using the
(non-abbreviated) procedure described in section 3.1. This action also
corresponds to the client moving to the INIT state in the DHCP state diagram."
I didn't find any specific waiting time after receiving DHCPNAK messages in RFC.
Is it fine to reduce this waiting time?
Thanks,
Saurav

Problem with reconnect to WiFi
by Pushkin Andrei
Hello. I use connman 1.12 with embedded linux on mips platform.
I implement my custom connman client with agent. But connman do no reconnect to WiFi:
1. I connect to WiFi (with PSK). Its connect.
2. I reboot my board. WiFi does not connect to AP after reboot. .GetServices show me:
object path "/net/connman/service/wifi_bc14efa91c57_50726f6d7761642054657374_managed_psk"
array [
dict entry(
string "Type"

)
dict entry(

)
dict entry(
string "Immutable"
variant boolean false
)
dict entry(
string "AutoConnect"
variant boolean true
)
dict entry(
string "Name"
variant string "Promwad Test"
)
3. When I choose connect in my application, agent does not ask password, and WiFi does not associate. GetServices :
object path "/net/connman/service/wifi_bc14efa91c57_50726f6d7761642054657374_managed_psk"

)
dict entry(

variant boolean false
)
dict entry(

)
dict entry(

4. My /var/lib/connman:

5. It fixed by removing all from /var/lib/connman/* and reboot board.

Fast connect path in wpa_supplicant
by Naveen Singh
Hi All
Just after losing wifi link because of an incoming deauth with reason
code 6 or 7, wpa_supplicant sets the fast_reconnect and
fast_reconnect_ssid to current bss and current ssid.
Later on if fast_reconnect is not NULL it tries to connect to same
SSID. This makes sense for some devices which does not use connman.
Devices using wpa_supplicant with connman this connect is not useful
at all as connman when it gets notified of this disconnect would
disable the network that would end up causing a locally generated
deauth and would nullify this connection attempt.
In stead of having this feature turned on all the time, it would be
good to have a configuration from connman. Initialized value of this
configuration would be turned on meaning fast connect is enabled and
devices using connman along with wpa_supplicant would disable this
feature.
Does this make sense?
Regards
Naveen

Wifi interface not recognized by connman
by Francis Leblanc-Lebeau
Hi everyone !
I have a yocto 1.8.1 build for a Zynq board with a Marvel 88W8787 wifi
device (wysbcvgxa chip).
The wifi device is not recognized by connman, but it is by wpa_supplicant
(named mlan0) and working if manually configuring wpa_supplicant.conf,
dhcpd, etc.
I am trying to find the problem as the connman debug prints don't give any
error AFAIK.
I have included the debug output for connman (debug.log), from this command:
# connmand -d -n -c /etc/connman/main.conf > /tmp/debug.log 2>&1
At first our build was using connman 1.28, but I updated to the latest
version 1.31 with the same results (which was used for this debug.log)
Here's more info from connmanctl output:
# connmanctl technologies
/net/connman/technology/ethernet
Name = Wired
Type = ethernet
Powered = True
Connected = True
Tethering = False
# connmanctl enable wifi
Error wifi: Method "SetProperty" with signature "sv" on interface
"net.connman.Technology" doesn't exist
Thanks in advance for your help,
Regards

[RFC 1/2] Storage based service retrieval
by MANIEZZO Marco (MM)
Hello,
I'm proposing changes related to the attached discussion, on retrieval of stored services information, in two RFC proposals:
RFC (1): Add a method GetKnownServices to the Manager that has similar behavior of GetServices but the source is not the active services list but the services stored in STORAGEDIR.
RFC (2): Deletion of stored service: as far as I understood, provisioned services (the one with a .config file) cannot be deleted with Remove method of Service, but after testing of the WiFi technology I saw that it is not possible to remove (STORAGEDIR)/service_folder/settings even if there is no .config file, with the Remove method of a Service. This will lead to an increasing storage unless manually file deletion is done. The RFC then is to change the _connman_service_remove function to actually delete folders and files, when possible, meaning I would preserve current conditions to return false in _connman_service_remove and moreover the .config files in (STORAGEDIR) won't be touched.
This email is to start with the RFC (1) modifications and see if my ideas are approved, because I made some assumptions that I hope are not a misunderstanding:
a) currently from Service component, using Storage component it is possible to access only information stored in (STORAGEDIR)/service_folder/settings and not (STORAGEDIR)/files.config. The latter is only accessed by Config component
b) the user can create a .config file in STORAGEDIR containing the information of connection (including passphrase for WiFi) of the services he already knows, so connman can connect (or autoconnect) to them without interaction. If a connection is made to these services with success, then a corresponding folder with a settings file will be created in (STORAGEDIR)/, that will reflects the .config file. Until a connection is done, only the .config file will exists. For services that don't have a .config file, after the user succeeds to connect to them the (STORAGEDIR)/service_folder/settings will be created.
Basing on the above assumption, mainly for (a) which would require further modifications, the GetKnownServices only retrieves the services that have (STORAGEDIR)/service_folder/settings; it will not read the content of the .config files. For our personal usage this is not a limitation because we won't have .config files, moreover the Remove method won't be able to remove them, but I'm open to change if you have suggestions.
Here's my proposal for RFC (1):
