Feature request: ability to remote control the app over serial

[lachesis]

I'd like to be able to issue commands to the app over serial. In particular, I'd like to be able to send at least the following:

upload_image <tagId> <page> <imagePath> (optional: image options)
upload_text <tagId> <page> <text> (optional: font options)
page_flip <tagId|(0 for broadcast)> <page> <duration|(0 for forever)>
blink_led <tagId> <duration|(0 for forever)>
send_command <tagId|(0 for broadcast)> <command> (optional: arguments)

The use case I have in mind is to leave a Flipper Zero plugged into my miniPC server and have it drive some tags around my office with different states once or twice a day. For example, one might show the weather forecast, or my meeting schedule, or whether I'm on or off air in a meeting, etc.

I'm sure this will wreck their battery lives but such is life.

I might take a stab at doing this myself, or asking Claude to do it, with reference to the stock IR firmware serial app.

Are there any immediate pitfalls, opinions, or suggestions that you have for me on this feature?

To be fair, I think you should use an esp32 with IR transmitter for this.

I was thinking about this too as a really awesome project but i feel like using a Flipper Zero for this is too unpractical.

With a strong enough IR transmitter you could put it anywhere in your room and leave it 24/7 without worrying doing updates all day long and I wouldn't also eorry about the ESLs battery life as it only wakes up when you send thr wake up command.

I'm working on integrating it to Evil-M5project which run esp32s3 😉

(Also find the way to change the brightness of the led during some test)

Just as a demo, I vibe coded up a little Python tool that renders this to the correct 2bpp format.

@7h30th3r0n3 I'd love to know any other commands you find around the LED color, brightness, timing, etc.

I'm working on this over in lachesis/raw-send-cmd. I opened a Draft PR #27 with a vibe-coded bad C "rawsend" command. It is only able to handle 128 bytes for now. I will maybe make that better if I keep hacking on this, but that's good enough for a few things for right now, like page-flipping a given tag by its PLID.

How did you @lachesis get a digital price tag? (I mean from where) I have been looking around to manage to buy one and couldnt find it :/
