Yosemite + Mindstorms EV3 = Bluetooth fail?

Prior to my upgrade to Yosemite, I had the Lego LabVIEW for Mindstorms EV3 connecting correctly via Bluetooth to the EV3 brick. After upgrading to Yosemite the bluetooth scan returns much too quickly to have actually scanned, and of course the EV3 brick isn't shown as a target.

Do we know if the APIs for bluetooth change in some radical way to break previously working software, or does this indicate some kind of malconfiguration on the laptop?

Only slightly related is the fact that to make WiFi work I had to turn off bluetooth per a suggestion on this thread (at least that works).

Thanks!

MacBook Pro with Retina display, OS X Yosemite (10.10)

So, Lego released a new version of LabVIEW which now works correctly. Just in time for FLL to be over.

Issue closed.

Don't see any updates. What do you mean?

After upgrading to LabVIEW 1.1.1, the bluetooth connection to the mindstorms brick works.

I was a bit slow in getting the response posted, so my apologies.

I have 1.1.1 installed and but able to connect by bluetooth.

Do you have the EV3 paired in the bluetooth control panel?

Dec 4, 2014 12:29 PM in response to paulprogrammer

I'm unable to pair devices.
1) Push Ev3 Pair in Bluetooth Settings.
2) Pairing dialog appears on Mindstorms Brick. Hit Yes.

3) The brick shows pass. No pass-code form appears on my Mac.
4) Hit ENTER. Pairing fails.

Try from the mac:

1) Open BT control panel on mac

2) When EV3 appears on device search, hit "pair"

3) select "OK" on EV3 BT pair confirm dialog

4) use PIN per usual

Good luck!

Also make sure iPod/iPad/iPhone is OFF on EV3 and EV3 is discoverable.

Dec 4, 2014 12:49 PM in response to paulprogrammer

Yes, it's discoverable, iPod/iPad/iPhone is OFF, bluetooth is ON.

Pin box does not appear on my Mac when pairing.

Confirming that JohnDavidson's suggested work around works for the EV3 (and latest firmware/software updates there as of 12-20-2014) with Yosemite:

"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."

The link seems to be broken

Thank you everyone for your posts.

I just upgraded to Yosemite and tried connecting the EV3 via Bluetooth for the first time. It was not working. When I upgraded the software (to version 1.1.1) & firmware (to version 1.07E), I was able to connect and download.

Thank you!

Macbook Air

OSX 10.10.5

Mindstorms EV3 Home edition v1.1.1

Brick firmware V1.07H

Unable to connect to EV3 brick via bluetooth

none of the above proposals work

anyone with new experience and solutions?

Nov 7, 2015 9:56 AM in response to pascal_fppw

Same problem with:

Macbook Pro

OSX 10.9.5

Mindstorms EV3 Home edition v1.1.1

Brick firmware V1.07H

Pairing with the EV3 only possible from within 'OSX bluetooth preferences',

Pairing succeeds with 'connected' in the bluetooth preferences display,

but after 2 seconds the preferences display shows 'not connected'

The bluetooth connection never shows up in the Mindstorms EV3 Home Edition software with the EV3 connected via USB

Any suggestions?
