[Bluetooth] pairing ray on ICS with blue&me

[#1]

Hello,

I have the blue&me system in my car (Fiat Bravo). It worked just fine with my ray on GB 2.3.4. My phone paired with blue&me without problem.

Since I updated to ICS, my ray doesn't pairing with the blue&me. It's trying but nothing happens. The keyboard doesn't appear to enter the pin code.

The blue&me is up to date and for my ray, I format the sd card before update. The bluetooth on my ray works, I connect it to other device without problem. Same thing for blue&me who still working with my phone's wife.

Have u any explanation (not including that blue&me sucks, I already know it )

Is there any article on difference of bluetooth between GB and ICS ?

Thanks,

PS ICS is working just fine on my ray, I have  difficulties to understand some excessive reactions...

Welcome to the forum.

It sounds to me like a typical case of incompatibility. Since the phone's Bluetooth is working with other stuff and this started after you updated, it's most likely down to your car system not supporting the software in your phone.

It's unfortunately pretty common that the update pace for phones outruns the update pace for software used in Bluetooth car systems.

Now, I don't know if it's as simple as your car system not supporting ICS at all or if it's just our software version that's not supported. Do you know if ICS is supposed to be supported?

What do you think about this forum? Let us know by doing this short survey.

Hello Markus,

thanks to the welcome and to try to help me

The blue&me site tells that the ST18 is fully compatible with software 4.0.1.A.0.283

http://www.blueandme.net/resources/Cellulari/SonyEricsson/Ray/start_E.htm

I suppose it's the software version of GB.

I don't see on their website if they are compatible with ics.

I think the bluetooth protocol doesn't evolve so are they any bluetooth parameters changed between GB and ICS like some response time ? Can I modify them ?

Harry_Bo,

Fortunately after I deleted my car system from my phone's bluetooth device list, turned Bluetooth OFF on both the Phone and Stereo and re-started bluetooth, I was able to re-pair the two.

But ... the Play/Pause button on my stereo does not work anymore.  Next/Prev track continue to work however.

I disagree with Markus.  The bluetooth profile standards are backwards compatible.  It would only be new features from the bluetooth on the phone that would not work with older devices which would not have support for a new profile feature.

Something is not correct with the Sony ICS update and bluetooth.

Hi Markus,

That looks like a slightly lazy answer, just to reply that the devices are incompatible

As Harry_Bo (and ply1740, below) explains, Bluetooth is a standard, albeit an old and somewhat lumpy one

I have had the same issue pairing my Ray with my 3 month old Opel (GM / Vauhall) - a model released more recently than ICS, so unlikely to be incompatible I would have thought

The connection worked better than any link between Bluetooth devices I've ever used before on Gingerbread (I've never had good experiences with Bluetooth in the past) until upgrading to ICS last night

Just spent a frustrating half hour trying to link the phone to the car - fruitless

My tablet, running on ICS pairs with the car audio system just fine, leading me to think that the problem is unlikely to lie with the car's compatibility with ICS and rather more likely to be an issue with the BT implementation in this Sony ICS upgrade

I'm gonna scour XDA developers and will report back if there's a hack anywhere to sort this

Meanwhile if anyone else has any suggestions I'd be really grateful to hear them

Cheers

btw, I'm new to this forum - is there any way of changing the "assumed answered" flag, since this ain't

Hello,

I issue the same Problem with my XPeria Ray ST18.

As my wife has the same phone and did connct it before(!) updating with ICS to her Blue & Me Carsystem (FIAT 500). And it is still working with it.

But after upgrade to ICS she (same as me) is no more able to do a new pairing(!) to Blue and Me Carsystem.

The Mobile's Firmware show's Build: 4.1.A.0.562 now - Android 4.0.3 (Kernel: 2.6.32.9-perf)

To make sure, that it is no kompatibility Problem to Android 4.0.3 (Kernel: 2.6.39.4+)I did pair my Tablet (Acer Iconia A200) with my Blue & Me Carsystem without any problem.

So I would assume, that there may be a little problem with with Bluetooth stack or driver for the ST18.

Hoping for an Hotfix

Regards, Bernhard

Hi,

today I had an upgrad from Sony for my ST18.

The Mobile's Firmware show's Build: 4.1.B.0.431 now - Android 4.0.4 (Kernel: 2.6.32.9-perf).

With a lot of expectations I tried agan to connect to my Blue and Me - still no connection

I eee Blue and Me as an available pairing partner, but it don't connect.

To see, that my ST18 is able to connect, I did a pairing with the above mentioned Acer Tablet PC ... without any Problems......

I still belive, that it could be a protocoll stack problem from the Xperia Ray

Hope it could help more,

regards, Bernhard
