125kHz fob not read / Protocol implementation?

[WilliamHF]

Describe the enhancement you're suggesting.

Hi,

Flipper cannot read a T5577 fob used for gate access.

The fob in itself is completely generic

Attached are ASK/PSK raw reads.
nvqnq.zip

Any help in decoding is welcome and appreciated if doable!

I have some additional fobs I can raw read if necessary to have multiple reads here..

Thanks

Anything else?

No response

Do you know anything about the gate control system itself? Vendor, model?

[WilliamHF]

Nothing at all unfortunately. No visible tags or brand on the reader. Could you confirm there is something valid encoded in the ASK or PSK dump?

[skotopes]

ASK looks good. Also if you have proxmark you can try to dump 5577 data.

[WilliamHF]

I don't unfortunately. Anything else I could try? Can something be determined from the ASK coding? I can provide raw read from a different tag if it helps.
Also, it seems the reader doesn't respond (no LED turning green or red) when emulating the raw ask data from the flipper.

[skotopes]

Flipper RAW data was never meant to be emulated. As for protocol itself: someone need to reverse engineer it.

This might be an Indala 224. It can be read with this
