Source? The Broadcom bcm43241 supports Bluetooth 4.0

I don't remember the source. I looked it up a while back and remember reading that the iPad 4 is the only tablet that currently supports 4.0
If you're right and can show me, that's great!

Bluetooth Low Energy aint supported even if it does have BT4. There is a bunch of issues right now..

Just look up the bcm43241 and you'll see its Bluetooth 4.0 hardware. I know its a bcm43241 because of the firmware that gets loaded.

These guys seem to think it's BT3

Who cares what reviewers say, they almost always get things wrong(Anandtech is one of the few trustworthy hardware sites)
The hardware is definitely Bluetooth 4.0.
Here's the proof:
Notice the bcm43241 firmware here: https://github.com/TheMuppets/proprietary_vendor_broadcom/tree/cm-10.1/manta/proprietary
Here are the specifications for the bcm43241:

The Android Bluetooth stack does not currently support BLE which makes the Bluetooth 4.0 hardware support moot. I've not seen too many devices that would benefit from BLE yet though.
BLE is working!
Installing a CM10.2 build on the Nexus 10 enables Bluetooth 4.0 a.k.a. BLE a.k.a. Smart.
cm-10.2-20130808.0946-UNOFFICIAL-manta
The app I used is to check this is
BLECheck-debug-unaligned.apk
Also there is a patch against stock JB 4.3 (Install JB 4.3, unlock, root, and installTW custom recovery) which enables BT 4.0.
I patched with the 4.3_BLE-tuna2.zip from

straight, I did not use the grouper-manta.rar files.
But enabling BT 4.0 is not enough, to test the hardware functionality I used
BLEScanner-0.1.apk (same thread)
It scans for BT 4.0 devices, and shows their BT id and the scanrecord. I tested with a Nordic nRF51822-EK loaded with the HRM firmware example from Nordic, it works. So it looks like BT 4.0 can be made to work on the Nexus 10.

OK,
Here's some information that should help clear up the BT 3.0 or 4.0 question.
First the semi-smug answer: "The Nexus 10 supported BT 3.0 before it supported BT 4.0"
The issue was the the hardware supported BT 4.0, but Jelly Bean 4.2.2 and earlier were BT 3.0 support and 4.0 required a custom ROM. As of 4.3, the STOCK ROM supports BT 4.0 and thus 4.0 is now supported! Please note, this does not mean that the vendor has provided the bits for BLE (bluetooth low energy), that feature may still not work. Thus is it working BT 4.0?
Nice that a feature is able to be provided via a software update. So much for the Apple exclusivity, but for those that look at pre-Jelly Bean 4.3 spec sheets, they'll only see 3.0.
So expect to fight about if you have it or not even if you can demonstrate it working. :cyclops:
Time will tell on the BLE front, but yeah, you've got BT 4.0.

Sorry to register for XDA for the sole purpose of resurrecting this old thread, but this thread is the #1 result on "normal" Google search for the search terms below and some extra info/questions may (or may not) be useful to other people doing the same search.
Search terms = Nexus 10 bluetooth
Like the folks who posted here previously I was also looking for the answer to "What Bluetooth characteristics/version does the Nexus 10 support?"
I ran into some info from 2014 in an ArsTechnica article where they talked with Dave Burke, the Google Nexus program manager.
That info, combined with the info above, leaves me unsure which of the following the Nexus 10 supports:
Bluetooth 3
Bluetooth 4 without BLE
Bluetooth 4 with BLE if you make a minor mod to the software environment yourself ("hack")
Bluetooth 4 with BLE supported by the default Android upgrade patches
BLE is the Bluetooth Low Energy feature of Bluetooth 4.
One paragraph from the ArsTechnica article of June 27, 2014 follows and a way to find the original article is below that. The person referred to ("he") is Dave Burke of Google.
"He also enlightened us as to why devices like the Galaxy Nexus, 2012 Nexus 7, and Nexus 10 don't officially support Bluetooth 4.0, even though the hardware itself is capable of it - Bluetooth LE was introduced in Android 4.3 and is crucial to extending battery life in devices like Android Wear smartwatches. Burke explained that supporting new wireless standards in devices often requires those devices to be re-certified by the FCC and other regulatory bodies. In the case of those specific devices, Google decided against recertifying them in the countries that required it, and decided not to support the feature in some countries but not in others."
On arstechnica.com search for "nexus-program-manager-says-nexus-devices-cant-ever-go-away" .
I would suggest that in the last line of the paragraph above the first "not" shouldn't be there and is a simple mistake while typing ... otherwise the sentence does not make sense grammatically.
Anouther (sorta) link to an earlier, related article from around the time that the original posts were made in this thread is ...
On arstechnica.com search for "review-android-4-3-future-proofs-the-platform-with-multitude-of-minor-changes" .
The top article says Bluetooth 4 came in with Android 4.3. It is now 2016 and my Nexus 10 is at Android 5.1.1 with strictly stock upgrades/patches, but I am unsure about the country certification stuff that is mentioned in the article paragraph above. Could Google be releasing slightly different versions of Android to people based on their IP address (country)? That is what the paragraph seems to imply.
Not that it really matters, but my Android version/build/etc. is listed below. I am in the USA and my IP is easily identify and as a USA IP.
Android version: 5.1.1. Android security patch level: 2016-04-01. Kernel version: 3.4.67-g84ad5a4.
I currently do not have any Bluetooth devices, but I am thinking about buying 1 or 2.

CM 13 supports BLE
I could connect my Nexus 10 with a BT low energy heart rate monitor and display heart rate, device info etc.
So the proof: The Nexus 10 hardware supports BLE (as suggested by previous posts) and at least with CyanogenMod it's also supported by Android.
I use CM 13 (Android 6.0.1) May 2016.
