* Fix signal calculation for WEXT-based driversGatis Paeglis2015-04-162-8/+15
| | | | | | | | | | | | | | | | | | | | | This patch introduces a behavior change. Previously the 'SignalStrength' role was interpreted as dBm. This was working fine for nl80211 based drivers, for WEXT-based drivers it contained garbage values. Now the 'SignalStrength' role will always be interpreted as percentage. The wpa_supplicant passes back only the 'level' of the scanned BSS, which with nl80211-based driver is almost always dBm (val < 0). WEXT-based driver has its own interpretation of 'level' - it can contain dBm, percentage [0-100] (and some other values for historical reasons, but these are converted by the wpa_supplicant to dBm). This is what I have concluded from looking at NetworkManager and wpa_supplicant sources and git history. Even the official GUI tool wpa_gui for the wpa_supplicant is out-of-date and can not be used as a referance.

* Pass "-D nl80211,wext" to supplicant by defaultGatis Paeglis2015-02-091-39/+49
| | | | | | | | | | | | | | | nl80211 is the current standard, but not all wireless chip's modules support it, wext is currently deprecated, but still widely supported. Supplicant will choose which of the these kernel interfaces to use for controlling a wireless driver on a specific device. This for example fixes the issue of QtWifi not working properly on a Nitrogen6_Max board with a wifi chip that comes on it by default.

* [Wifi] graduate from Qt.labs.wifi 0.1 to B2Qt.Wifi 1.0Gatis Paeglis2014-12-0216-0/+2536
- Make wifi library available from c++ 1) included with "#include <B2QtWifi>", available classes are: QWifiDevice, QWifiManager, QWifiConfiguration - Re-design of API: 1) connectedSSID -> currentSSID get current network from this property instead of networks state change events 2) networkStateChanaged(QWifiNetwork *) -> networkStateChanged(NetworkState) Don't expose QWifiNetwork objects to library users, use data model roles instead, no need to pollute API with "read-only" class. The flaws of exposing QWifiNetwork become apparent when looking at C++ API. 3) New BackendState enum for backend state changes events, backendStateChanged(BackendState) Initializing backend can be lengthy operation and can block GUI thread, same is true for DHCP requests, now these operations are moved into a separate thread and backend state change events are delivered asynchronously. 4) Make WifiManager a Singleton, we don't want several instances starting and stopping system processes and it makes global state handling simpler. 5) Rename Interface -> WifiDevice 6!) Introducing QWifiConfiguration. This abstraction allows for easy way to add new features, whatever we choose to support from: http://w1.fi/cgit/hostap/plain/wpa_supplicant/wpa_supplicant.conf The idea for it is to be a Qt-style wrapper for "network {}" configurations from wpa_supplicant.conf. Also this makes life simpler for developers if they know what network they will be using, they can omit scanning, listing, selecting parts and do something like this instead: WifiConfiguration { id: config ssid: "network name" passphrase: "12345678" } if (!WifiManager.connect(config)) print("failed to connect: " + WifiManager.lastError) - Optimizations: 1) Async. event delivery. 2) eLinux: Don't use "ifup", it is slow because it starts dhcp request even before any network has been configured. Use start-stop-daemon and ifconfig directly. - Bug fixes (many), but most importantly: 1) Get backend state properly when WifiManager is created. - Public header cleanup - Other: 1) Added categorized logging. 2) Methods to get/set wifi interface name. Not exposed to qml. - Missing parts that will be added as a separate patch: * [doc] Getting started guide for c++ and qml * [doc] Update for qml docs and new docs for c++. The current docs are out-of-date. Task-number: QTEE-649 Task-number: QTEE-810 Change-Id: I7dc8709aed2de622828a119749aef31534a4296d Reviewed-by: Laszlo Agocs <laszlo.agocs@theqtcompany.com>
