Re: Error reconnecting to a hidden AP.
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.

Re: Error reconnecting to a hidden AP.
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.
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.

Re: Error reconnecting to a hidden AP.
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 enabled in the binary?

Re: Error reconnecting to a hidden AP.
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?

Re: Error reconnecting to a hidden AP.
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.

Re: Error reconnecting to a hidden AP.
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 On Thu, Dec 4, 2014 at 10:00 AM, Joaquim Duran wrote: > Dear all, > > I'm working in Gem-med company (http://www.gem-med.com).
