Can we decode wifi signal?
-
@jsulm Hi;
I really appreciated your reply! I want to develop a Qt application in which I need to scan the whole wifi running around where I will install my application. I need to scan the wifi SSIDs and the corresponding MAC Address to each SSID. I want to read this information from the wifi signal. Please provide me help.
Thanks in adavance! -
Is it possible to decode the wifi signal in qt creator?
@Mijaz No. Qt Creator is a glorified text editor. I assume you mean a program developed to use the Qt libraries.
The basic Qt libraries do not, as far as I can tell, contain any cross-platform facilities related to wireless hardware configuration or scanning. From a user program, wireless scanning (i.e. triggering it and retrieving results), status monitoring, and interface configuration needs to be done with operating system specific APIs (e.g for Windows). The user program never "decode the wifi signal", that is a kernel driver function. Once a wireless association is made, and configuration by the operating system complete, Qt can see the interface created and communicate via it as for any wired connection.
The Qt Device Creation commercial offering used to have some wireless hardware capability usable with the Boot to Qt (B2Qt) functionality. In this environment there is often no user-facing operating system to handle the configuration.

AP units are not required to broadcast the SSID. It's often not broadcast, as a security measure.
