But that requires some hardware hacking
You could use TTL serial port <-> USB adapter which are very cheap.

From what I see on photo, soldering should be easy, because these are pads.

For now, I hope to find a working example by someone who has already done the wifi setup with a Flucard or similar card.
LOL but what is the hack then ?

If you use EyeFi card then you are able to connect to AP, but not possible with FluCard ?

UPDATE: Code below from K-S1 can "connect" to existing AP or "establish" a new AP...

I have no idea how the Eye-Fi system works internally. It's not even clear if it uses a similar Linux setup. All the articles that talk about the Linux on the Flucard and Transcend cards never mentions that this is similar to Eye-Fi, so I doubt I can get into the Eye-Fi system as easily as into the Flucard. They're obviously not sharing the same setup.

What does your code show? Is that from the camera side again? The strings suggest that it's probably not. So, did you disassemble the busybux of the Flucard here or what are we looking at?

See my updated comment above. I suspect: camera decides if it makes new AP or not. Not a flucard.

Not yet.

Yes and yes. But an Eye-Fi card does not communicate with Pentax cameras. It only provides a file server to the files it has stored on its Flash drive.

So I don't think it'll help us in any way.

I ran into a more serious problem with the Flucard, though. I modified only the startup script a little by turning off the buzzer. I don't believe I've made any changes to the network (wireless) setup scripts. Yet, after these changes, even though the Linux system comes up fine, the http server on the card doesn't work any more - but the WLAN hotspot still works, ie. I can connec to the card's Wifi network and get an IP via DHCP assigned, but connecting to the web server times out.

I wonder if Pentax has added a second hacking protection level there, checking if the initramfs or parts of it have been messed with. After all, the "code" subdir of the firmware update for the Flucard contains some cryptic files, and one of them ("version") kind of looks as if it contains a MD5 or SHA checksum: 76 CA C9 9B 96 ED 9B 9E 30 60 B8 81 13 C5 0C 18 2E 60 C8 71 03 06 8B 18 30

The code inside "index.html" is also encoded or encrypted, no idea yet how.

The file "html", also part of the firmware updater, is an ELF executable that contains a reference to the "/code/version" file, so I guess I'd have to look there to see what this file is about. But not anytime soon, got some other things on my mind right now.

This is not correct. It is recognized in firmware and some special actions are done.

Do not think so.

Hi all,

Can I know what is the command for the flucard to release the shutter?

Thanks.

IMHO you guys should be helping shodan with hacking PENTAX firmware instead of hacking around on an SD-Card... ts ts ts...

Well yeah, in a perfect world I would agree, but poking around with some http commands and Javascript in the SD card's WiFi API is a world away from making potentially damaging changes to assembly code in the camera's firmware!

I'll stick to what I can handle, TYVM.

I disagree. It's obvious people care about this just as the others care about custom firmware. Why not just encourage people to follow their hacking passions with the equipment they own. Shodan is working on a K-30 and these folks are working on a FLU card. Two very different pieces of equipment that not every hacker owns nor can afford.

Besides, the more the merrier. What if Shodan hits a snag and there's a breakthrough with the card? Aren't we bystanders better off then?

Very interesting to be sure, but I would probably focus my efforts on reverse-engineering the K-S2's native wi-fi. That might be an easier (and more beneficial) starting point since there's currently no desktop support. Plus, the native wi-fi range is far greater than that of the flucard, which opens up more practical uses.

I wouldn't be surprised if the two were very similar in their implementation.
did you do?

Is there any progress on your side with this flucard-hacking bootcoder?

tempelorg gave up... (At least he told me so via e-mail.)

The API is exposed in the html. It is reasonably simple to access. The challenge is writing something useful. I've had ideas and looked around a bit but got more interested in something else.
