Only one bluetooth device at a time?

Only one bluetooth device at a time?

I got a new phone today, but all my music is on my iphone. I quickly discovered I can pair both the old and the new phone, but I can't use one for calls and the other for music. Is this entirely expected? I was going to pop the sim card out of the iphone to see if it made any difference, but haven't had a chance to try it yet.

Yes - only one Bluetooth phone can be connected at a time. It's easy to switch between phones by hitting the BT icon.

Would be nice if multiple phones could be connected at the same time - so that either phone (if called) would be automatically routed through the car.

I thought that would be nice too because i have work phone and personal phone. Then I thought about the software having to support call waiting between those two and my other passengers' phones ... And it is pretty easy to disconnect one and reconnect the other as long as BT on for both.

Yes, only one is connected at a time and every car I have had works the same way. I leave my phone playing Google Music, and it automatically picks up where it left off when I get in the car. I would hate for my wife's car to automatically start streaming the music when I get into it without having to do something :).

It is easy to switch to any paired phone, so I don't see the problem.

Moving the SIM card isn't going to help, as the Bluetooth id isn't related to the SIM at all (and operates just fine with no SIM).

i want to use my ipod for music and my bb as a phone. I thought I had it working that way when i first started with the car but now it only lets me use one at a time. not sure how that will work if I get a call when I have the ipod streaming music

How about using the USB for the music and bluetooth for the phone calls if you have 2 devices? That way the streaming device can remain charged.

Tom - It doesn't work. Only one Bluetooth device at a time for music and phone. If your iPod is connected, your phone will not work through the car.

I spent a frustrating few minutes figuring that out. A person would think, one for music and the other for phone. It doesn't work that way.

@hpjtv: sadly, the USB ports in the MS do not work with audio devices. They are only usable with a USB flash drive loaded with non-copy protected files.

Continues to drive me crazy that there is no way to hard connect an audio device to this car. Even a bottom of the line Corolla Model L offers both an iPod-connectable USB port AND a standard 3.5 mm audio jack. The lack of either means that you are unable to use, for example, a high resolution audio player like a Pono or an AK100. You're stuck with low-res Bluetooth.

With physical USB ports in place, how hard could it be to add support for iPod-type sudio devices? Would solve all these "need two BT connection" issues.

@clinresga I didn't realize that. Maybe it's just related to Apple. My wife's Samsung S5 works fine with the USB. You just have to set in the phone as Mass Storage Device instead of Data connection.

clinresga | February 12, 2015

@hpjtv: that makes sense. The USB ports only work with "naked" files on either a flash drive, or in the case of the S5, a hard drive. But it will not accept an actual audio signal that is "downstream" of a DAC. Thus eliminating the option of using higher res DAC or file formats, or using a file management system such as iTunes to play your music. | February 12, 2015

Best quality is had by using USB with lossless files such as FLAC. Going through extra D/A and then A/D is a poor way to do it (i.e. audio plugs). You might as well stay with bluetooth.

Unfortunately for Apple products, they have their own standards rather than using existing standards (such as having the devices look like a standard USB drive).

This is added revenue for Apple as just about everything from connectors to software requires paid licenses. I'm not saying this is bad, or that Tesla shouldn't license Apples proprietary standards, just that this is the way it is, and it adds considerable engineering effort to support Apple products.

The lack of options for connecting music is frustrating. There is only *one* good way and that's a USB memory stick with your library. That's it.


1) apt-x support for lossless bluetooth streaming. Using BT would be acceptable if Tesla supported the apt-x codec in the a2dp profile. Pretty much every receiver these days including headphones supports this profile. Nearly all Android phones, Macs, and PCs support sending apt-x. There's no excuse to not have it.

2) No auxiliary line level input. Even if you don't want separate 3.5 mm connector in your design, there are pins in the usb standard that cary line level audio. My Infiniti does this through a special 3.5 mm to usb cable.

3) No iOS integration. Pretty much every auto manufacturer that sells cars in the US has iOS integration. Most cars have it and millions of people use it including myself. I leave an ipod plugged into our infiniti in the center console and it syncs over wifi automatically whenever new stuff is added to itunes so our library is always up to date in that car. And before you fanboys try to say it's an outdated interface, you're simply wrong. It's the current standard and used by pretty much everyone.

Any of the 3 methods above would be acceptable if only one of them were supported.

To the original subject. In our infiniti, you can connect a media device and a phone device. They can be different devices or the same device. It's doesn't care and why should it? Tesla needs to fix this.

Remembering that Elon Musk suggested the new approach will be to let the phone do most of the work, I will also add my vote to request multiple Bluetooth devices to be connected simultaneously, at least for the different BT duties, but ideally, more than 1 phone, (and eg. 2 address books, etc.) connected at a time.

I'd also agree that we need to be able to have the best possible Bluetooth audio, considering that there is no line-in Sorka I don't believe analog audio input is possible with a typical 4-conductor USB, it's just power and digital data). But I am fine as long as Bluetooth is at its best.

For folks really frustrated with the lack of line-in, you might not want to discount an FM broadcasting dongle, after all they can usually be had at a discount eg $10-$15.

I'd also like to see the FLAC standard be formally supported, and hopefully we can then address the skipping and song crashing.

I just use USB stick that has my music library. I have a good CD collection I just rip them into FLAC with EAC. I still like to buy CD that I can have a physical copy too.

The standard bluetooth protocols on most cars do not allow multiple connected devices for the same function. cannot have two phones or headphones linked at once. This is therefore not within Tesla's control.

There is an exception, a new bluetooth (4.2) now available on BMW motorcycles, that allows two headsets, with simultaneous communication and music listening - and two phones, but each individual phone must be linked to a different headset.

To Puntoteague Dave's last comment here: not sure that is accurate that most cars do not allow. In the 2012 Mercedes ML 350 we have I can connect several BT devices which allows me to use 1 BT Phone and 1 BT music player (in this case iPhone for phone an iPad or iPod for music streaming). That same option was available in a 2015 eGolf we drove for a while as well. Seems a very basic thing to allow streaming music through BT without impact the phone BT connection.
