The Sun affects the range? How and why, that doesn't make sense at all?

> How and why, that doesn't make sense at all? Not sure. I remember reading an article some time ago that stated the Sun's electromagnetic radiation could interfere with Bluetooth and it's always worked with my observations. I've used multiple Plantronics headsets, Motorola headphones and an off brand of headphones all with an iPhone 5S, iPhone 6+, Nexus 6P, Moto X and a Note 3 and in all of these devices they work g…

Another, as likely, aspect, is that Bluetooth is designed around signals bouncing off surfaces. Try moving your phone from one side of the body to the other while outside. It may well be that your surroundings do not provide enough signal reflection. Keep in mind that most mobile bluetooth radios do not transmit with the same strength as wifi. Best i can tell, only USB dongles use a wifi equivalent radio class.

I don't need more range or more speed. I need it to reliably connect and stay connected while devices are well within range of each other, and stop breaking every time I upgrade anything. Unfortunately that would require making it less complex, which is about as likely as a broken egg spontaneously reassembling.

I'd just like to have paired devices actually automatically reconnect without having to unpair and repair. The only things that seems to do this reliably are PS4 controllers with my PC.

It can be done with BT - the $15 headphones I buy from random Chinese sellers work fine every time. The implementations seem to be at fault, not the protocol.

I need the range. I routinely grab my phone when I'm cooking dinner and walk to the living room causing my bluetooth speaker to make awful noises.

Is the bluetooth spec the limit though, or maybe the implementation? I can leave my phone on the table downstairs and my headphones still work fine in the attic, which is through 2 floors of reinforced concrete. I was very surprised to be able to do this, but kitchen-living room should be possible. Unless your kitchen is in the west wing, and your living room is a mile down the hall in the east wing in which case I'm…

Iirc, there are multiple classes of bluetooth radio. And only one of them, that i have most often seen in the form of USB dongles, are wifi equivalent.

That problem seems to be specific to Android. I had Samsung ATIV S, which did not have this problem at all (Win Phone). However both S3 and Nexus 6 have it. The later I bought in part to make it go away at least partially:(

Indeed, they made a mess of it twice - right around when BlueZ finally got good, they switched to a different stack on Android 4.2 and broke everything again.

Remind me, was that before or after bluez introduced a pulseaudio dependency?

I'd also like it to consume less power. I know the current standard touts itself as "low-energy" but I can see a very noticeable increase in battery drain when I have it enabled on my phone. So I always keep it disabled.

This is really a poor marketing job by the Bluetooth SIG. Bluetooth 4.0 added BLE, the low energy mode, but it didn't change anything about the power usage of existing modes. BLE is almost and entirely different protocol, albeit implemented on the same chipset, which is running alongside the existing Bluetooth stack on your phone. Nothing in the Bluetooth 4.0 spec reduces the power usage of the Basic Rate and Enhance…

Seems similar to the mess that is USB 3.1.

One would be lead to believe that 3.1 and the C plug is one and the same, But they are not.

There are actually 3 different specs that the OEMs can combine in various ways.

First is the C plug spec, that can be used with or without the Power Delivery and 3.1 data spec.

Then there is the 3.1 data spec, that is so minor an update to the 3.0 spec that effectively all 3.0 devices are 3.1 compatible. It can be used with A and C plugs alike.

Then there is the Power Delivery spec. This promises that you can get up to 20V out of a USB port, any USB port. Yep, you can encounter A ports that can go up to 20V if you have the right device and cable at the other end.

I'd highly recommend getting a tiny mp3 player (say Clip Zip, though they are now discontinued...) and a short light headphone cable. Why send audio wirelessly when the tech to play it is as small as the receiver? There are also headphones with built in players, I don't know how the quality of those is though.

Why send audio wirelessly when the tech to play it is as small as the receiver? Because you might want to stream audio from the Internet, or you don't want to waste time converting newer audio formats to MP3 and then copying them over, or you'd rather not have cables around you when you work out, or you might want to track what you've listen (particularly useful for audiobooks and long podcasts), etc. Yes, these are…

So you'd be happy with a Chromecast Audio receiver built into a set of headphones?

Wonder why it was not thought earlier? After BT we saw development in WiFi,GPS, RDID etc. Nobody thought that BT could help indoor for the shopping mall usecase present in the article.

Now they are planning for late 2016, means it will only be available in new phones from 2017

Pretty much all the decent dedicated MP3 players have been discontinued. The last really great one for me was the Samsung's range (nee Yepp). But unfortunately the last one was the YP-U7 back in 2012 and it's very obvious they aren't going to make any more, even though they never announced it. Sony still does players but they're not very good.

Care to elaborate on that? I find the Sony players deliver what they promise, especially the NW-A20 series.
