IPhone 4s bluetooth not working

OK. Let's try one more time. The iPhone has never supported bluetooth file transfer. You cannon pair one iPhone with another. Some apps can communicate with other phones using the PAN bluetooth profile. This does not involve pairing the phones.

You can't do that.

I have been using my original iPhone with my Sennheiser MM400 for a long time...no problem (well, actually, from time to time the Sennheiser would lose connection but I always figured it was my fault for getting too far away from the phone or something).

This week I got my new iPhone 4s.

The first interesting thing I noticed is that it had some difficulty connecting to my Ford Sync bluetooth. I finally made that work.

However, it will not recognize the MM400 at all. I have tried several of the ideas in this thread with no luck. I am running the latest ios.

I was able to pair the iPhone to my Motorola H780 (with siri off...have not tried with siri on).

I suspect that Sennheiser's bluetooth may be partly to blame, but there may be some shared blame with Apple as well.

I use Keynote on iPad.

I bought the Keynote remote this afternoon for my iPhone 4s but I couldn't use the bluetooth connection to link up both device.

Hope it'll be fixed soon.

I also run keynote on my iPad and successfully used the keynote remote app on my iPhone 3s. Recently upgrading to an iPhone 4s, my iPhone and iPad with not discover each other. My iPhone 4s will not pair up with anything using Bluetooth. This needs to be fixed, a phone that without working Bluetooth isn't go to work or me.

Thanks Nick. I tried what you said, turned off both the siri and the location services, and got my MM550 headphones to sync with the 4s. Once the 4s had initially recognized the headphones, I switched both siri and the location services back on. I have not had any issues since with the two syncing.

Why on earth Apple does not want to admit that bluetooth installed on iphone4s does not work

It does not search for any device i bought the phone recently and it does not connect to my cars bluetooth kit

Where as my iphone 4 connects properly apple need to figure it out and not try to ignore this issue

I recently upgraded from iPhone 4 to iPhone 4s and my Bluetooth has worked only once to pair to my cars hands free Bluetooth. It no longer recognizes it. I have tried and tried. I will try disabling Siri to get it to re-sync but it was synced once and not sure why it no longer works. Apple needs to fix this glitch. My iPhone 4 never had a problem.

Hello Deborah, If disabling Siri does not work, try switching off location services aswell, and then sync. (then switch Siri and location services back on.) The 4s is a great phone. There is usually a way around problams. I did not had any issues syncing the phone with the blue tooth in the car with both Siri and Location services switched off.

Hi all,

I have an iphone 3GS and a new 4S. The 3GS was previously Bluetooth enabled for my Mac mini to use 'Remote' around the house, and also in the car. Since i added the iOS 5 and also the 4S to our lives, nothing works for bluetooth connectivity. The phones simply cannot connect to any device.

The addresses appear (Chevrolet.... Mac mini...) but the wheel will continue to spin - and not connect. This is extremely frustrating..

Apple, I'm an excellent customer, but this lack of connectivity - I blame solely on upgrading to your new iOS - is terrible. I will not support this company further - and should I mention the battery life issues on the 3GS ??

iPhone tethering or personal hotspot is supposed to work via Bluetooth.

GroovyCruiser, I join you in thanking Nick. After years with other phones(never had an apple) I took the dip on the 4s. I had it for four days now, after setting everything up I went to pair it with my helmet, Nolan with N-Com system; Nothing, I started trying to pair it with my laptop and garmin nuvi, nothing, even with my brother in law`s iphone 4. It just kept searching without finding anything. I was going to turn it in tomorrow when i found this thread. Disabling siri and locations, and I got connected first time both with my helmet and garmin. cheers🙂

Not sure why you are having trouble, but my 4S, bought on Dec., 2, pairs nicely with my device in my car. Just followed the instruction of my device, and it worked first time. Same with my wife's 3GS, both on IOS 5.01. It's not a general fault.

My iphone 4S works with two cars. But it can pair with Nokia BH-208, it failed to deliver the sound to the BH-208. All sound through phone speaker.

Yes we hear you when you say iphone never has supported bluetooth file transfer. It is totally unacceptable that the iphone still does not support bluetooth file transfer. This is hardly new technology, having a new device that is supposedly at the leading edge of technology and not supporting this is poor.

For me my use of the phone involves bluetooth file transfer, so the iphone is not much use for me. Luckily I had a colleague that has iphone so I found out before purchasing a phone, about the inadequacy in regard to bluetooth file transfer.

Also when i turn my bleu tooth on on my IPhone 4s, my Wifi on my Imac turns off every 3 a 4 minutes !!

And my sennheiser MM450 cause WIFI problems on my Imac....
