Yosemite + Mindstorms EV3 = Bluetooth fail?

having same problem,3 hours on phone with apple yesterday. today I can not receive email;

Oh and Im the phone now for over an hour, not happy with Yosemite

Basically the same problem here. Bluetooth control panel shows the EV3. Clicking "pair" goes through the process, but disconnects after a few seconds. This is with four EV3 units using different firmware versions including the latest. Up until I upgraded to Yosemite there was no problem, and bluetooth connections were very stable.

This is with a Macbook Air and a Mac Mini. EV3 bluetooth connections on Windows are still working fine.

Obviously something fundamental has gone wrong with Bluetooth in Yosemite.

Hello

I have just got off the phone to Apple Support and they have said this type of issues has affected previous operating systems not just Yosemite. However, there is a simple fix which we went through which involves resetting the System Management Controller (SMC) and the Parameter Random-Access Memory (PRAM). All seems to be working fine since I did the resets (Maybe even faster!).

To do this go to the following apple support sites -

• Intel-based Macs: Resetting the System Management Controller (SMC)
• OS X Mavericks: Reset your computer’s PRAM

I have a MacBook Pro (Retina, 15-inch, Early 2013), Processor 2.7 GHz Intel Core i7.

I hope that helps.

Unfortunately, it seems you have not been provided with the right information:

• This problem has not been apparent on my three Macs using Lion, Mountain Lion, or Mavericks. It has only become apparent using Yosemite.
• Resetting the SMC and Pram has had no effect on the problem.

Unfortunately, the problem still exists.

It seems Apple has configured the Bluetooth configuration in order to interact with IOS in another way.

JohnDavidson and paulprogrammer are like me still waiting for an helpful information but Apple always

is sleeping.

I prefer to go back to MAVERICK OS!

Just pilling on. We have three identical iMacs, a MacBook Air, and a MacBook Pro, all connected to EV3 via BlueTooth without a problem. When we upgraded the MacBook Pro to Yosemite and tested EV3 software, the only thing that didn't work was BlueTooth connection. Needless to say, we didn't proceed to upgrade the other computers and don't plan to until we get to the bottom of this.

Perhaps the solution:

If you are using the educational software of mindstorms (V1.1.0) there are problems connecting the brick via Bluetooth in Yosemite.

This software is not yet updated.

But when you download the latest free software of mindstorms (V1.1.1 - note the different One) you should not have these problems any longer - i just tried it!

The 1.1.1 update to the home version seems to have resolved the problem ... I hope.

Downloaded version 1.1.1 on both MB Pro (Late 2011) running Yosemite 10.9.5 and on the 2014 mac mini. The BT issues still persists.

It was working very nicely on the MB Pro before the upgrade to Yosemite. Seriously considering rolling back OS now if trip to genius bar fails this weekend.

i got the same problem with a new macbook pro. Hope there will be a fast resolve.

OK. The 1.1.1 update does still mean that you cannot pair the EV3 bricks using the System Preferences Bluetooth panel. You need to follow the procedure here:

I know people have seen this document before, but the technique does work.

You can only pair the EV3 from within the Mindstorms program. Do not attempt to pair directly with OS X, so don't use the second mechanism in the above document. It won't work.

You will also find that the connection will only be stable while Mindstorms is running. Once you close Mindstorms, the bluetooth connection will be lost.

This has worked for me. The connection was stable for 4 hours before I got bored watching it.

Same issue. Apple & Lego please fix this!
