Still no audio profile that supports Opus. Why are we still using a 20 year old audio codec (SBC) for Bluetooth speakers? Opus is low enough bitrate that it could even theoretically be used over BLE (ignoring latency problems), while still wiping the floor with SBC. Regardless of whether BLE transport is possible, it depresses me that Opus support still hasn't been added to the A2DP.

We got brand new 25 year old codec now! PATENTED and owned by Qualcomm https://en.wikipedia.org/wiki/AptX

I tried to use that and after I received an expensive aptX-LL capable receiver I found out my Google Pixel doesn't support aptX!

I've been wanting an Opus powered headset too, for years. Maybe someone can make a non-A2DP opus receiver and some type of virtual audio device in PC and Android?

Yep, I wanted to love Bluetooth for keyboards, but my Logitech and Microsoft wireless keyboards (work and home, respectively) work great with their proprietary receivers (basically like a wireless wire), while the Logitech K810 has random key lag and connectivity issues (try typing your password when Bluetooth doesn't work and you can't log in to re-pair it). Windows 10 also seems monumentally bad at Bluetooth, and I…

> try typing your password when Bluetooth doesn't work and you can't log in to re-pair it Haha. That reminds me of the classic, " Simply goto to http://example.com/drivers to download the network drivers for your new desktop ".

I once bought a brand new Acer Aspire series desktop. Shame it didnt ship with network drivers preinstalled...

Considering every phone I've tested (iPhone 5S, iPhone 6+, Samsung Note, Moto X, Nexus 6P) with 7 different bluetooth headphones (ranging from cheap Amazon ones to expensive LG) I have NEVER found a phone, paired with headphones, that stayed connected especially when the phone is in my side pocket and I'm walking in an open space which seems to make connectivity significantly worse. For instance getting on the BART b…

Getting 2.4GHz through the human body is hard. The human body is mostly water, and bluetooth is, after all, the same frequency of your microwave oven, which uses 2.4GHz because it's in a band of frequencies from 1-20GHz that water absorbs. When you're indoors, you don't need to get bluetooth through your body. You're getting reflections off of nearby walls and ceilings which allow your bluetooth devices to communicat…

It's actually a really easy problem to solve with a cord. I have this exact same problem with bluetooth. I have to put my phone in my sweatshirt pocket or in a higher pocket in my backpack or it cuts out.

But thanks for the explanation. This is good to know. I'll plan my walk to and from work through alleys instead of open parks. Because thinking back, it always works in alleys.

Oh great. More powerful transmitters at 2.4, and everyone is wearing at least a couple of them. I just got my wifi channels sorted. Talk about range and connectivity all you want. 2.4 can only take so much before everything starts fighting with everything else.

And KSP just updated too.

Engineer's solution: drink less water when you want to use your wireless headphones (also, for a few days previous)

The Logitech 810 is a fantastic keyboard however I pretend to ignore the connectivity shortcomings that you describe... What I would like with the Logitech keyboards and mice is an option to plug in with micro USB or to go Bluetooth, i.e. wired but detachable if your Bluetooth happens to be reliable that day. There already is a micro USB socket for power on the 810 keyboard, sadly they don't do a mouse that charges o…

What use cases do you find Bluetooth keyboard / mice enable? Maybe I'm old fashioned, but I've never been able to come up with a compelling answer for myself.

I picked up a pair of Bose QC35 a couple of months ago, and for my first pair of BT headphones I'm really impressed. I use them almost every day on my way to and from work (roughly an hour each way) and I can count the number of interference issues I've had on one hand, and definitely not every 30 seconds. This is with an iPhone 7 and iPad Pro 9.7". They're not cheap, but I'd highly recommend them.

Can confirm, got the Quiet Comforts myself about a month ago and use them every day. Use them with my S7 Edge, Surface Book, cheap 20$ bluetooth dongle connected to my gaming PC and a fat 2012 13" MacBook hand-me-down at work. The only machine I have problems with is the MacBook, to the point where I'd rather just play music from my phone all day than fight with it.

Is Bluetooth 5 compatible with 4.x? That is, can a Bluetooth 4.x Central connect to 5 Peripheral (or vice versa)?

Does anybody know the power usage (idle, advertising, data transferring, etc.) of BT 5 compared to BT 4.x LE?

Thanks

Has anyone here had issues with bluetooth interference from.. traffic lights? My Sennheiser Momentum wireless headphones seem to be running into this issue. It doesn't happen all the time, but when it does I notice it happens when the traffic lights switch (e.g green to red). There must be some kind of signal interfering with bluetooth that's emitted at that point, though I can't understand why since all traffic ligh…

Yes! Every intersection in downtown Chicago I have this same issue with my Jabra Revo bluetooth headphones. I'm not sure if it involves the lights switching, but I always get audio cutting out very badly when I'm waiting to cross the street.

And not just traffic lights. I'm in Melbourne, Australia and every day I walk across the concourse above Southern Cross station (major rail switching hub), and at a certain point my BT phones (also Jabra Revo) keep dropping out, then recover as I move past that black spot ("blue spot"?)
