Idk. Flipper0 pretty damn cool and fun. Some one in my neighbor hood is sending packets on 299.999. I've caught a few. Just fun stuff trying to figure it out.

Its super battery efficient. Its also super cute and fun to have a tomagatchi type device. I love mine.

Edit: rtfa. These alternatives are cool, and honestly, wifi and bluetooth on the Flipper0 would be great. But none of the mentioned alternatives even remotely compare with regards to the breadth of tools the Flipper0 has. Its an all in one with a cool dolphin companion. I'll definitely go in for the Flipper1 if its got wifi and bluetooth, but i'd be bummed if it gets much bigger. The package size is great with the flipper 0.

I just recently got my flipper - was buying some long range nfc stuff, and noticed they had that in stock, so decided it is cheap enough to just get it and figure out later what it is about.

I'm very pleasantly surprised - sturdy hardware, well polished software, and very good documentation. It is just a great thing to always have in your pocket - digital companion to the swiss army knife I always carry.

I have a lot of more powerful specialized equipment - which pretty much everything in the article is. But most of that isn't really suitable enough to always have it with me - not versatile enough, or limited options without attached computer. flipper is great to just have a look around - and to know what to bring next time, if there's something interesting to investigate further.

edit after having it a bit longer: The versatility of the flipper is still unique, and makes it a pocket knife you just want to carry - but it shows problems on specialist use, probably mainly because it still is a relatively new device. If there's a chance I want to interact with HF NFC I went back to carrying my proxmark (rdv4 with bluetooth addon, small HF only antenna) as well - can read/dump more card types, and has less bugs for card emulation. I still use the flipper to get a first impression, though - it just has the better standalone UI.

A big problem of the proxmark is the need to recompile the firmware for different standalone modes - to make that less painful on the road I've now added packages of git head for Tumbleweed on OBS which contain all possible standalone firmwares for PM3 generic and RDv4 with and without bluetooth.

Can you give more details on the packets on 299.999? I don't understand what you mean there

[–] [email protected] 4 points 1 year ago

So when you are in frequency analyzer you can see packets come through. I keyed in on 300 mhz as a frequency that 'something' was happening on. So then I switched over to 'Read', set it to 300mhz, turned it to AM650 modulation and Bin_RAW on. I'm catching output that looks like below. I'm not sure what it is. I tried parsing it a bit but no luck so far.

Maybe 299 MHz? Although their website says it broadcasts to other Flippers at 433 MHz...
