Start: send the payload. The toast shows the control page address, for example "Keep Awake v enabled / Control it at http://192.168.1.50:9031".
Turn off and on: use the control page. Turning it off lets the console go into rest mode, but the payload keeps running, so you can turn it back on from the page without sending the payload again.
Close: use "Close Keep Awake" on the page (tap twice to confirm), or send the payload again. This ends the payload, so it needs sending again to start.

Only one copy runs at a time. It uses TCP port 9031 to know whether it's already running.

Control page

While it's running, open http://<console-ip>:9031 in a browser. The page shows:

whether Keep Awake is on or off, and for how long,
which console it's on,
a button to turn it on or off, and a link to close it,
a QR code for the page. Open the page on a computer (or the console's browser) and scan the code with your phone's camera to control Keep Awake from your phone.

The page also has a small HTTP API:

Request	Does
`GET /status`	Returns JSON: `version`, `console`, `active`, `uptime` and `since` (seconds since start and since it was last turned on or off), `interval`, `ip`, `port`
`POST /on`	Turns Keep Awake on, and returns the status
`POST /off`	Turns Keep Awake off without closing it, and returns the status
`POST /quit`	Closes the payload

For example: curl -X POST http://<console-ip>:9031/off, or make quit-ps5 PS5_HOST=<ps5-ip>.

Building

The Makefile expects the SDKs next to this folder (../ps5-payload-sdk and ../ps4-payload-sdk). Set PS5_PAYLOAD_SDK or PS4SDK to use them from somewhere else.

make                              # build both
make ps5                          # or just one
make ps4
make test-ps5 PS5_HOST=<ps5-ip>   # build and send
make test-ps4 PS4_HOST=<ps4-ip>

Both builds need LLVM (clang, ld.lld, llvm-objcopy). The Makefile uses Homebrew's LLVM automatically when it's installed. Otherwise, set LLVM_CONFIG to your llvm-config.

The version is set by VERSION in the Makefile. It goes into the filenames, where Payload Manager reads it, the toasts, and the control page.

Working on the control page

The page is src/index.html. The build embeds it into both payloads with xxd. To try it without a console, run the PS5 code on your computer with the console calls stubbed out:

make host && ./build/keepawake_host

Then open http://localhost:9031.

Releasing

GitHub Actions builds both payloads on every push to main. To publish a release:

Bump VERSION in the Makefile and commit it to main.
Tag the commit and push the tag: git tag v1.1.1 && git push origin v1.1.1.

The workflow builds the payloads and creates the GitHub Release with them attached. It fails if the tag doesn't match VERSION.

Source

src/ps5.c: built with the ps5-payload-sdk.
src/ps4.c: built against libPS4 from the Scene-Collective ps4-payload-sdk. libPS4 has no select(), so this version checks for connections ten times a second.
src/web.h: the HTTP server for the control page, shared by both.
src/index.html: the control page, including a small QR code encoder (byte mode, error correction level M, up to 106 bytes).
