My brand new Iphone7 seems to have bluetooth problems in my car. Everything works but the sound drops sometimes (often) when I listen to music. I didnt have this issue wiyh my 6s and IOS10. I tried to reset everything but the problem persists. The iPhone is recognized by the radio inmy Toyota, but the sound drops just as it was a radio in a tunnel.
iPhone 7, iOS 10
I provided this to the techs weeks ago, but it seems like there was no headway. So here are the results of my trials for everyone to read:
I work in an environment where I have access to soundproof rooms. The walls are steel with padding and are about 6" thick (solid). These are "dead spots" for wireless in my building, which I surveyed and had to plan around because of the walls. I also work with deploying a lot of iOS devices, so most of my colleagues have an iPhone.
Testing environment:
I tested the area with an OptiView XG using AirMagnet Spectrum XT software. This device and software is used to measure the amount of Radio Frequency (RF) radiation in a given area to troubleshoot issues with wireless, and to help design wireless networks for large corporations. This helped me to ensure that there were no stray 2.4GHz interferers while testing, meaning that the only devices emitting 2.4GHz band RF were the "Devices" listed below (Beats Pill, Plantronics Backbeats, Braven BRV-1) and the phones.
Additionally, I tested the cars listed below in several environments with and without interferers nearby. These were less controlled, however mirrored the exact same results.
Stuttering/Skipping:
To show an example of the skipping sound that I am referring to, please take a look at this video: https://www.youtube.com/watch?v=kGHFDRVA958
Bluetooth devices tested:
iPhones tested:
As you can see, the issues are localized to the GSM models using the new Intel modems. This further solidifies the belief that there is an existing hardware issue and not a problem with software, interference, or other manufacturer's devices. I'm not sure what else I can do to troubleshoot with the Apple reps, but after spending upwards of $5000 with Apple in 2016, I can't help but to feel neglected.
I have a 6s running 10.0.2, using AT&T. Bluetooth works fine in my vintage Miata (aftermarket Pioneer DEH-6700BT stereo). I admit I was a little worried when I stumbled across this thread after updating, but I played music and audiobooks on my hour commute with no trouble.
Apple usually tends to lag on hardware, then moves to the newest stuff. That's usually not a problem; replacing a Bluetooth headset is a lot easier than replacing your car. Given the size and expense of that particular peripheral, it probably would have been a better move to stay backward-compatible for another cycle.
Confirmed iOS 10.1 pb 3 works great with Ford Sync and seems to fix all issues.
AT&T? Glad to hear your problems are fixed.
Wish I had your luck. Also on 10.1 PB 3 and I still have all the same issues.
DO you have AT&T? I think AT&T has more issues.
I just downloaded beta 3 (installed on iPhone 7+ | at&t ) and jumped in my car (2015 Lexus GS) and I drive for 6 mins through an area with 1 bar LTE service and no skips. As soon as I got in are where I have 5 bars it starts skipping. It's skipping as I type this. So I also see connection with LTE inteferance.
so that's a negative for beta 3 bluetooth fixes on Lexus.
Unbelievable. Last time being in the first in line for another apple product...
Update to last comment-- drove back the same way I came, with issue, as soon as my phone switched to 4G in poor coverage area no more skips. Turned around went back and as soon as I hit LTE it cut out. So I have definitely figured out a test area.
Very disappointed and I wish I could bill apple for all the hours I have spent troubleshooting this.
One final note: the sound quality of the beta 3 is worse then the previous 2. I can now put volume on handset and head unit all the way to max. I reconnected my iPhone 6+ just now and they same song is like night and day. The 6+ is way louder and much more crisp and defined. 7+ is very muffled (compressed).
seriously. mine is working, driving around with LTE the whole time. And it sounds great. This was tested previously many, many, times and I always used to have issues with LTE coverage, usually immediately. Unless the new iOS has introduced some kind of delayed onset to the connection flaws, I have to believe that this problem is being worked on (and so far seems fixed in my particular vehicle). I have been submitting feedback on experiences with my car with each new beta release, and have noticed some degree of change with each of them. So I like beta 3. Maybe even more vehicles will be compatible with the next release.
Who is your carrier? AT&T?
Verizon?
yes, i thought i established that earlier, but I am using an iPhone 7+ on AT&T in a busy area on the East Coast. Driving a 2014 Ford ST with Sync system. The GSM iPhones use different LTE bands, and so I have always assumed that it was something to do with these extra bands that was causing bluetooth interference. As someone with some programming experience, I think the simplest solution, if nothing else works, would be to simply disable those bands when the phone is connected to bluetooth. The user would never know and the total experience would be greatly improved. I am not sure how Apple is approaching this, but it does seem to be taking excessive amounts of time to remedy for all users.
I have really only done two tests so far with beta 3, so it is possible that some issue could still crop up, but I have been testing this for awhile now with 5 different os, and this is the best I have seen. As of now, its perfect. Of course, it could also be that the atmosphere of the earth in my area of the world just happens to be currently in such a way as to hinder the propagation of certain radio waves in the LTE spectrum. But that is more far fetched than to simply come to the conclusion that something has been fixed in a software release put out for the purpose of fixing and testing.
iPhone 7 Plus, AT&T, 2015 Ford Escape w/ Sync 2 MFT v3.8.
Still suffering from the stutter, speedup, disconnect issue with iOS 10.1 Beta 3. The issue occurs after 15-30 minutes of driving and then is so bad I can't listen to music. So Beta 3 didn't fix it for me.
Thanks for catching me up. Appreciated.
Has anyone tried testing in a Kia Optima at all yet? That's the car I have issues with (Pairing Failed message), and I'd be very curious to see if they've done anything that fixes it.
update: beta 3 is not perfect on long drives. It is definitely improved over previous versions, however, as it does not disconnect or skip. There is still more fixing needed, but I think things are headed in the right direction.
