I'm doomed... 😟
Finding Easter eggs is hard you say? Try a datasheet 😑

Maybe proprietary controller with data sheet only searchable by Chinese search engine! You are doomed none the less.

@yendenikhil most likely yes. Eh, it's a decent controller and I'm not too familiar with QFN packages anyway. So I've just put it back together and called it a day. Kinda nice how they used plastic pins and holes to put it together though.. makes disassembly super easy, unlike when they use glue.

Try Bing - sometimes it is surprisingly accurate at finding precise model numbers and spec sheets, even more than google

@endor no way 🤣 you have to be kidding me!!

@Condor Way. Google manipulate their results so much as to make them irrelevant when looking for specific factual information. There's a huge amount of bias towards social media, celebrity news, shallow events, you name it.

Bing still serves manipulated results to a degree, but they are often of far, far better quality than Google.

@endor there should be a search engine/client that gathers results using multiple search engines. I'm not surprised if there already is.

@Condor totally serious. It's also why it's better at searching for porn and stuff: it's worse at general context, but great for specific details - like that autistic kid who can barely speak to people but can do mental math faster than you with a calculator

@monr0e how about DuckDuckGo? They tend to tout about how they don't "personalise" their results 🤔

@electrineer sounds like you're talking about searx 🙂

@electrineer but how do you rank the results you get from the engines? How do you decide who did a better job for that specific search?

You don't have to do all the indexing by yourself, but still have to solve the same ranking problem, just one layer up

@Condor that's bullshit, and don't you believe it. They seem to avoid tracking, as much as I can tell without analysing what they do with my browser fingerprint, but without a doubt they will be taking money at least for running costs. Certain search terms will yield certain results with a greater bias, and suggestions will be manipulated too.

It is foolish to believe any online service that claims, in 2018, not to be using sponsorship in some form.

@monr0e I fully agree. Hence why these days I tend to prefer searx, as I can deploy that on an internal server. Until that's done though, I'm using https://searx.linux.pizza i.e. the one from @Linux 🙂
Speaking of which...
No datasheets, just my own bloody rant 😭

0. There is a portal exclusive for data sheets
1. You are looking at a clone, you may like to try to find the original one.

@rookiemaverick
0. alldatasheet, I know.
1. Probably. It's a €1 dongle so it's gotta be. No idea what the original is, if any.
2. This isn't Stack Overflow, is it?

@Condor
I was just about to mention the alldatasheet website...

@Gregozor2121 it's an amazing site after all ❤ but even they don't have the datasheet for this particular chip 😢 I've been sold a black box 😭😭😭

@Condor I totally missed the Bluetooth part, you are really doomed my frn.

Indeed it's not stack overflow.

@Condor Why are you trying to find its datasheet anyway? Do you want yo hack it or is it broken and you are trying to fix 1$ dongle?

@Gregozor2121 nah, the reason is far more trivial than that.. Shits and giggles 🙃

@xzvf there you go 🙂

@Condor

haha!

you can change the theme, what search engines it is going to use and customize it more in preferences!

@xzvf I'm not on Reddit 😢

@Linux oh, nice! 😃
*applies dark theme straight away*

@Condor Is there an FCC-ID on the case? Also did you read out the USB vendor and product ID, might be a hint, however if it is a clone the USB IDs are probably faked as well.

@Condor Also if it works under Linux you can just check which driver is used and there you know your chip (or at least on which chip the clone is based on).

@bootleg-dev no FCC ID (this isn't America 😉) but inserting it into a Linux machine to get more info isn't a bad suggestion actually. I'll give it a go in my Arch laptop tomorrow 🙂

@Condor any updates, I'm genuinely curious. My current guess (pulled out of my ass) is that it shows up as a Broadcom chip :)

@bootleg-dev Haven't checked to be honest. My laptop has recently become stable again, so if I can remember to do it tomorrow I'll be able to give you some results. Broadcom wouldn't surprise me though, from my experience they're notorious for holding back source code for any product that they're able to or can get away with.

.

@Omnisus Looks like this was just as much a reminder for you as it was for me, haha. Thanks for getting me to check this again, otherwise I would've completely forgotten :')

@bootleg-dev Cambridge Silicon Radio apparently.. other than that, no specifics in "lsusb -v" other than "Bluetooth Dongle (HCI mode)". Meh, it's a €1 dongle so as long as it serves the purpose, I'm cool with however the manufacturer achieved it.

@Condor Interesting (and not unexpected), my guess it is not a genuine CSR chip tho. Can you give me the vendor and product IDs, out of curiosity?

@bootleg-dev In case you're interested, the full output of lsusb -v for that dongle is at https://clbin.com/RsYi0. The vendor and product ID's are 0x0a12 and 0x0001 respectively.

@Condor Looks like a CC2541 clone. But it's hard to tell. Maybe you can use the pinout and check if those matches with your board.

@Crowns from the looks of it, that may very well be the case. I'll add this stuff on "the list" for now (€1 BT adapter.. I mean.. yeah) but I've downloaded the datasheet for this suggested controller. Thanks for mentioning this!

@Condor It's just a wild guess because it's widely used in this mini Bluetooth devices. But yeah, 1€ device and a Chinese manufacturer with it's own labeling is hard to find out. Maybe you can find some information in the arduino forums when searching for HT6630.
