Provides P2P (WiFi Direct) session management for wpa_supplicant, as used in the PiPedal project.
For support, please go to the PiPedal Project page.
Built as a submodule in the PiPedal Project Build.
The project is currently fairly tightly coupled to PiPedal. The current implementation addresses PiPedal's needs adequately; but there's functionality missing for a general-purpose library.
If there's interest, I could be convinced to speed up the development of a full component library. (nudge nudge sponsor sponsor. ;-P ). But that's fairly far down my list of personal priorities.
Please rename binaries and libraries if you fork the code. Not doing so will break your installs and mine. And there's a good chance that some or all of this code will get upgraded to a more generally usable component.
What's provided:
-
P2P (WiFi Direct) session management for autonomous groups (no GO negotiation), with LABEL authentication only. (i.e. a fixed pin that would be printed on a label attached to the bottom of the device).
-
Fast reliable pairing with Android devices.
-
Runs on the dhcpcd network stack used by Raspberry Pi OS.
-
libcotask -- a fairly effecient and interesting C++20 coroutine library providing co-routine-based I/O on sockets (not yet for filesystem objects). Mostly documented through a doxygen build. It's bound for general release, but not there yet.
What's not provided:
-
Proper keypad, display, pbc authentication. (Needs a control socket to interact with UI).
-
Provides P2P UPNP service discovery. Needs P2P DNS-SD service discovery.
-
Support for more than one running autonomous Group is designed-in, but incomplete (Raspberry Pi can only run one GO anyway).
-
Testing and configuration for newtworkd-based network stacks.
-
Automonous GO only.
-
Testing on fully-compliant C++20 compilers coroutine implementation. (Raspberry Pi OS only supports G++10.2).
-
Switch the coroutine library over to iouring libarary in order to get asynchronous file i/o as well.
A CMake based build and VSCODE configuration files are provided. Actual production builds are done using this project as a sub-module of the PiPedal project. Installation and systemd configuration are also done in the PiPedal project.
Depencies are pretty minimal. libuuid, and libsystemd, and that's probably it.
