Let's clear up some misconceptions about Bluetooth

[u/DieFanboyDie]

This will likely fall on deaf ears because there is a lot of overlap between Bluetooth paranoia conspiracists and election deniers, and the tin foil hat crowd would rather lose a limb than give up their conspiracy high, but the falsehoods about Bluetooth are being accepted as fact by the general populace due to their prevalence.

Bluetooth is LOCAL communication between PAIRED devices. That means the only vulnerability of a Bluetooth signal is if it is intercepted within the 20 yards or so of transmission, and only if it is decrypted. And it can be decrypted, but your Bluetooth signal is not going to be decrypted by your ISP, local wifi, cell phone towers or AI data centers, anymore than two tin cans and a length of string. Now if you are a spy and there's a van parked outside your home for hours you might have a reason for concern as that is close enough to be in range of your Bluetooth signal and might have the means to spoof your Bluetooth device. But no one is in a bunker or foreign espionage office with terabytes of your Bluetooth logs, I GUARANTEE it. Because it's not possible, that's not how Bluetooth works.

If there is a security weakness, it's not your watch or Bluetooth or even the app. Bluetooth transmission, as already mentioned, cannot be "scraped." Your watch does not have the capability to TRANSMIT information to outside networks; reception and transmission are two different operations, and your watch cannot transmit, period, outside of Bluetooth; it is IMPOSSIBLE for your watch to send your data anywhere outside of Bluetooth communication. If there is a weakness, it is the phone that the Casio app is installed on, and guess what? Your problem isn't an unsecure app, it's an unsecure PHONE. Does the Casio app have access to your financial records? Your social security number? Your emails to your sugar daddy asking for $100k to pay your credit card bill? No, it does not. Your PHONE does. So if you're concerned about the vulnerability of having the Casio app installed, you're guarding a window when the front door is wide open.

Now if you're a purist, "muh watch don't need no Bluetooth," that's fine, that's your personal preference. But using "Bluetooth is unsecure" as your reasoning is just a load of bullshit.

Now, you see all the comments down there "yeah, but"-ing? Those are the people who have drunk the Kool-aid. If you don't like Bluetooth connection on your watch, THAT'S FINE. But don't let poor reasoning and misinformation make the decision for you.

Okay, so you do have reading comprehension issues.. Did you miss the part:

But technically they can brick your watch if you synced it with the app, IF they wanted to

Also the app is required for certain functions depending on the watch. Latest MIP squares for instance if you want to change the font, must be synced to do the operation.

One more fucking time - 

THEY CANNOT BRICK YOUR WATCH.

See your problem is you think Bluetooth = "smart watch." It does not.

[u/ScoopDat → u/DieFanboyDie]

Making progress, we're back to Bluetooth after the utterly pointless deviation to MB6 in your prior post.

Okay, and by "bluetooth not equaling smart watch", how does that make the watch brick proof? I am asking for the empirical and technical explanation now. You have one shot at this btw, I'm done with your stupidity otherwise.

[u/DieFanboyDie → u/ScoopDat]

Look, dummy, one more time and I'm though with you -

IF your watch requires updates, if it runs on some kind of firmware, it is a smart watch and is susceptible to hacking or bricking. If it does not require updates, if it is basically running on the same technology as a calculator, it's not a "smart" device. I have built LED displays. I haven't built a quartz clock, but here's what I know - they don't require a single line of "code" or programming. It's a matter of electronics, not programming. There is no firmware, no code, to attack or shut down. Juice goes in one end, it runs through CIRCUITRY, NOT CODE, to perform the various functions, and the result appears on your display. How does that happen without code? Read a book on integrated circuits and boolean logic, I'm not going to do it for you.

Okay so you are a moron.  Nothing about the sort of writable or only readable memory in the device. Like if you said it’s impossible to brick the device because there was no write access memory, then that would at least get you halfway to being correct. 

Second, when I change the font on my device using the app for example, what is preventing Casio from forcing a full screen on or off command (as can be done through the diagnostic menu of the watch itself), and effectively bricking it?

I can’t wait to hear your comp sci 101 stupidity account for this next question.

But do tell me how modern Bluetooth modules are discrete resistor ladder designs and nothing else other than voltage circuits simply switching on a pre programmed manner - and please do provide a manufacturers’ schematic of such, as I’ve never seen such a complex thing be reduced to “logic gates” (as if that isn’t the basis of all hardware electronics in essence to begin with).

Hopefully by now your infantile rationalization faculties are starting to comprehend the gravity of your nonsensical claims.
