Haven't look at the spec yet, but curious if they've improved the security side of communications. edit: Here's what I'm referring to, bluetooth 4 LE mode is vulnerable to certain attacks: https://lacklustre.net/bluetooth/Ryan_Bluetooth_Low_Energy_U... https://pomcor.com/2015/06/03/has-bluetooth-become-secure/

I was not aware of this[1], thanks for linking. Do you know whether the same is true for non-LE connections? I always thought those were secure, provided there are no bugs in the implementations.

[1] The paper's conclusion summarizes very nicely, though they write it formally and a little confusingly: the thing is utterly broken. They can read contents, even if they key exchange was not observed/captured, and they can inject traffic. Basically it's obfuscated plain text.

Why is general bluetooth connectivity so "buggy"? Why am I always struggling connecting my iPhone 6s to my bose bluetooth speaker? I would love to understand that.

I have problems with Macbook + JBL xtreme. It's not working. But any other combinations working fine: macbook + any other bluetooth speaker (i have 4 different speakers + headphones) and several mobile phones + JSB xtreme. Just magic.

I think we'd need an RF engineer to answer this more thoroughly, but it's my understanding that there are a lot of materials capable of absorbing the low-energy microwaves that it uses as its transmission medium.

Water is a big one, which I think is one reason that having my phone in my back pocket almost always results in a dropped connection to my headphones over the course of working outside for a few hours, compared to my side or front jacket pocket. Too much water in our tissues.

Both endpoints have to have perfect implementation, or: your connection is only as good as the worst of the two devices.

I cannot think of a single way in which Bluetooth has changed my life. Of the Bluetooth devices I have, I do exactly the same things I've always done, just with slightly more annoyance.

My smartphone let me answer emails and burning questions on the go, while also letting me give up my car. My VR headset is making me completely rethink what User Experience means to the point of making the current usage of the term UX just downright laughable.

But that's actually beside the point. I don't actually need Bluetooth to change my life. I need it to get rid of the wires in my life.

And if it worked as advertised, I could do that. But Bluetooth devices... they're just always a tad sucky. And the ways in which they just feel bad is in the secret society handshake of doom you have to do every time you want to use the device because it's 2016 and for some reason my devices still can't reliably pair with multiple other devices.

And then once they are connected, the latency in the communication almost makes them useless. I can't use Bluetooth headphones to play games, which is usually when I want to wear headphones. I can't use Bluetooth in any of my motion tracking wearable hardware prototypes, which is ostensibly the sort of thing Bluetooth wants to cover.

Something that might work for me: decouple the Bluetooth pairing from the host computer. Make it a part of the dongle. Make a dongle that is basically the wireless equivalent of a USB hub, and it's to that that I pair my devices. I'd be happy to bring that dongle with me everywhere I bring my Bluetooth devices. That might actually let me use my Bluetooth mouse on my home PC, on my laptop, and on my work PC.

Finally, would someone please design a decent, full-sized keyboard, with Bluetooth support.

Wow, this press release is horrible. Full of useless business jargon. Ctrl+F "IoT": 9 results. Why do they write these things? The only people who care about bluetooth press releases are tech-literate enough to understand at least mildly useful information about the new standard.

As someone who is building an applied AI hardware product, what can we expect from BT5 ?

> Key feature updates include four times range, two times speed, and eight times broadcast message capacity. Longer range powers whole home and building coverage, for more robust and reliable connections. Higher speed enables more responsive, high-performance devices. Increased broadcast message size increases the data sent for improved and more context relevant solutions.

When will the chips be shipping anyone know?

Bluetooth is complex. Lots of devices have crappy software which gets things wrong. And it doesn't help that the 2.4GHz band is full of radio noise, either. But most of the problems aren't with transmission, they are with setting things up and turning things on and off. Crappy software.

Also, it doesn't help that everything in Bluetooth until BLE (Low Energy) arrived was pretty bad. BLE changed everything and turned Bluetooth around, but BLE doesn't do audio.

There is lots of confusion in the naming, Bluetooth 4.0 incorporated BLE, and later they decided to just call the whole thing Bluetooth, even though it's now a set of two entirely different protocols, not even radio-compatible.
