Re: Error reconnecting to a hidden AP.

2014-12-07 Thread Tomasz Bursztyka

Hi Joaquim,


Finally We've fixed the issue that connman was not reconnecting to
hidden wifi's. These are the list of changes that we've done:

1 - When compiling wpa_supplicant, in the config file disable the options:
CONFIG_AUTOSCAN_EXPONENTIAL
CONFIG_AUTOSCAN_PERIODIC
CONFIG_BGSCAN_SIMPLE

>From wpa_supplicant config documentation, if any module of autoscan is
enabled (periodic or exponential) autoscan is enabled. (suggested by
Tomasz).


Keep CONFIG_BGSCAN_SIMPLE, that one is something you want if you are 
roaming.

In your case, only the 2 first ones are the one you need to disable.



2 - Change the contents of /etc/wpa_supplicant.conf file to

ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=0


IMO, in the connman documentation, It should also be specified the
contents of wpa_supplicant.conf file.


No because there is no need of any wpa_supplicant.conf when 
wpa_supplicant runs with DBus.


This configuration file is relevant only when wpa_supplicant is running 
with its own unix
socket interface used for IPC, usually for stand-alone usage via wpa_cli 
or others.

Hi Joaquim,


In wpa_supplicant, you're referring the option CONFIG_BGSCAN_SIMPLE, isn't it?


No, that one is fine and useful for roaming. I was referring to 
CONFIG_AUTOSCAN_EXPONENTIAL

If you don't have it, then it will be fine on that level.

I wouldn't say that ConnMan's autoscan is always better than using autoscan 
through wpa_s for every device. In real life experiment we did enable the 
CONFIG_AUTOSCAN_EXPONENTIAL after founding out that it behaves better on our 
device. 

So it varies..

Re: Error reconnecting to a hidden AP.

2014-12-05 Thread Tim Tisdall
After a lot of searching, it seems that the best way to determine the
configuration switches used is to look at the package build log such as
this:
https://launchpadlibrarian.net/168444110/buildlog_ubuntu-trusty-armhf.wpa_2.1-0ubuntu1_UPLOADING.txt.gz

It looks like it has DBSCAN on but no AUTOSCAN.

This is interesting...  I'm using wpa_supplicant that comes with the
package handler for my distro.  Is there a way to tell if that feature is

Could we have a patch to that documentation and not enable it by default
if we are?

Hello,

We're using connman 1.26 with wpa_supplicant 2.3.

In wpa_supplicant, you're referring the option CONFIG_BGSCAN_SIMPLE, isn't it?

Hi Joaquim,

Which version of ConnMan are your using?

Also, do you have wpa_supplicant built with autoscan support? If so, 
rebuild it without that option.
I think ConnMan's README advises to enable it but it's a mistake. 
ConnMan's fallback autoscan

is better since it handles properly the hidden SSIDs.

I think you may have to give more details...  I'm working on devices that
also connect to a hidden wifi in a hospital and I'm pretty sure it's made
re-connections properly.  I'm using a config file like this:

[service_hospital]
Type=wifi
Name=hospital-wifi
Passphrase=password
IPv4=dhcp
Hidden=true
