Re: Bluetooth 5
#2I've been really fascinated recently by whipping out my smartphone in public and using a Bluetooth LE explorer app to look at what's being advertised, and it's brilliant. We are all constantly surrounded by devices which are screaming data about themselves everywhere they go.
Bluetooth 5 seems to increase the range of LE communications, but since I'm almost sure we're going to have some horrible public hack of one of the platforms at some point, I hope there is increased focus on the security of devices that use it!

It's also terrible that people, and their clothing, are so detectable in the visible light spectrum. Where's the 'tarnkappe' when you need it?

Also appreciate the "will be marketed as 'Bluetooth 5.' [no dot zero]". Sounds like a band name, or a gang. Good thinking there - the Bluetooth 5 are now taking over the neighborhood ...

#4Isn't it time for uncompressed A2DP audio at last? It would solve both quality (generation loss) and latency issues.

Perhaps you would like to explain what the problem with this is? Broadcasting presence in itself is not a security hole - unless you think "Do not broadcast SSID" is a WiFi AP security feature (it's not). If WiFi can be secured (with devices that "scream data about themselves"), why would Bluetooth be any different?

Not sure what the GP is using, but on Android the Nordic BLE app is very good - https://play.google.com/store/apps/details?id=no.nordicsemi....
I'm also one of the authors of RaMBLE, another BLE app (https://play.google.com/store/apps/details?id=com.contextis....). It can run in the background, and can export logged BLE advertising packets and geolocation data to a SQLite DB.

The best on by far is Nordic's Master Control Panel. It's really good. Only available on Android though. I don't think there are any good ones for iOS.

#9Increased advertising length will be very useful. 31 bytes is rather stingy, especially with Eddystone-URL (you only get something like 16 bytes for the URL currently).

aptX already allows high-quality audio streaming over BT and has both a lossless and a low-latency mode. Device support is also already here, I saw a few last time I was in an electronics store.
