Some iOS 11 issues show early adoption pitfalls, others are just growing pains | Ars Technica
...Disabling Bluetooth and Wi-Fi in the Control Center
In the previous version of iOS, tapping the Bluetooth button in Control Center—the one-stop shop interface for basic phone functions like brightness, volume, and connectivity—completely disabled Bluetooth on the phone, but that is not the case in iOS 11, perplexing many users. According to our tests and a support document from Apple, disabling Bluetooth connectivity from Control Center only disconnects currently active Bluetooth pairings and prevents new pairings until it's re-enabled. But the Bluetooth hardware is still going. The same is true of Wi-Fi...

Why your iPhone and iPad don't fully disconnect from Wi-Fi and Bluetooth in iOS 11 | iMore
Don't worry, nothing's wrong with your phone: everything is as Apple intended it.
If you've recently installed iOS 11, you may have noticed that no matter how many times you toggle Bluetooth off in Control Center it's still automatically on when you reboot your phone. It's not just you. Nor is it a bug — that's actually just how the operating system works. Not a huge deal if you're privy to that particular information, but without seeking out the specific support page on Apple's website, most of us who were used to iOS 10 had no way of knowing about this feature change.
Now when you tap to power Bluetooth or Wi-Fi down in the new Control Center, it doesn't shut them off completely. Instead, it just disconnects you from most accessories or devices you may have been connected to and disables auto-join capabilities. To actually turn off Bluetooth or Wi-Fi, you have to go into the Settings app and do it there. All of this is because Apple wants to keep users' connection intact so they're able to utilize things like Air Play, Air Drop, Apple Watch and Apple Pencil, even if they wish to disconnect from other devices.

Bluetooth 5.0 and the New iPhones — MacSparky
One thing I haven't seen much written about is the addition of Bluetooth 5.0 to iPhone 8 and iPhone X. According to the Bluetooth standards commission, the big change with version 5.0 is increased range. (The last few updates have focused on reduced battery usage.) With Bluetooth 5.0, the range is now supposed to be up to 800 feet (240 meters).

Gas Pump Skimmers - learn.sparkfun.com
For those who don’t want to read through the gritty details here’s the summary:

These skimmers are cheap and are becoming more common and more of a nuisance across north america.

The skimmer broadcasts over bluetooth as HC-05 with a password of 1234. If you happen to be at a gas pump and happen to scan for bluetooth devices and happen to see an HC-05 listed as an available connection then you probably don’t want to use that pump.

The bluetooth module used on these skimmers is extremely common and used on all sorts of legitimate products end educational kits. If you detect one in the field you can confirm that it is a skimmer (and not some other device) by sending the character ‘P’ to the module over a terminal. If you get a ’M' in response then you have likely found a skimmer and you should contact your local authorities.

Turning Off Wi-Fi and Bluetooth in iOS 11's Control Center Doesn’t Actually Turn Off Wi-Fi or Bluetooth - Motherboard
"in iOS 11 and later, when you toggle the Wi-Fi or Bluetooth buttons in Control Center, your device will immediately disconnect from Wi-Fi and Bluetooth accessories. Both Wi-Fi and Bluetooth will continue to be available." That is because Apple wants the iPhone to be able to continue using AirDrop, AirPlay, Apple Pencil, Apple Watch, Location Services, and other features, according to the documentation.

Turning Off Wi-Fi and Bluetooth in iOS 11's Control Center Doesn’t Actually Turn Off Wi-Fi or Bluetooth - Motherboard
Lorenzo Franceschi-Bicchierai:
<p>when you toggle Bluetooth and Wi-Fi off from the iPhone's Control Center—the somewhat confusing menu that appears when you swipe up from the bottom of the phone—it actually doesn't completely turn them off. While that might sound like a bug, that's actually what Apple intended in the new operating system. But security researchers warn that users might not realize this and, as a consequence, could leave Bluetooth and Wi-Fi on without noticing.

"It is stupid," Collin Mulliner, a security researcher who's studied Bluetooth for years, told Motherboard in a Twitter chat. "It is not clear for the user."

To be clear, and to be fair, this behavior is exactly what Apple wants. In its own documentation, the company says that "in iOS 11 and later, when you toggle the Wi-Fi or Bluetooth buttons in Control Center, your device will immediately disconnect from Wi-Fi and Bluetooth accessories. Both Wi-Fi and Bluetooth will continue to be available." That is because Apple wants the iPhone to be able to continue using AirDrop, AirPlay, Apple Pencil, Apple Watch, Location Services, and other features, according to the documentation.

Motherboard tested this behavior on an iPhone with iOS 11 installed and verified that Bluetooth and Wi-Fi remain on in the settings after turning them off in the Control Center, as some users have started to notice.</p>


OK, so let's get all the iOS 11 bugs/features (this one's intentional) out of the way early on.
