[Q] How Can I Update Bluetooth from 1.9.2 to 2.0 (+)

I have been searching for days trying to resolve this. I have a new cordless landline phone (Uniden) that has a great feature where it will bond to my mobile via Bluetooth ... allowing me to accept and make mobile calls via the cordless landline handset. When I try to bond though - it fails.
I read the Uniden instructions - and they say it requires Bluetooth 2.0 or greater ... and my HTC Touch Pro 2 (Australian Telstra version - initial release version from a couple of years ago) has version 1.9.2 Build 600.
I read that the more recent models of the Touch Pro 2 have Bluetooth 2.0, so I ordered a replacement HTC Touch Pro 2 and it arrived today. Sadly - it has the exact same bluetooth version as my 2 year old version.
Next - I try to flash the ROM (thanks to ENERGY ROMS). It works great - but the bluetooth is still 1.9.2 build 600. So I flash the radio. It works great - but the bluetooth is still 1.9.2 build 600.
Around about now - I realise that I don't have a clue what I am doing and that randomly flashing things hoping for an update is not the way to go. So - can anyone out there please help me to figure out how an HTC Touch Pro 2 can have it's bluetooth updated to 2.0 or beyond?
Many thanks,
Scott

Can I drop my Bluetooth version from 2.1 back to 2.0?
Looking further into this - I have noticed that despite the Bluetooth module reporting version 1.9.2, if I look at Device Information (Hardware) - it reports that I have "Bluetooth version 2.1/2.1 + EDR". This has me thinking that my problem is actually that my Bluetooth version is beyond the spec that my Uniden cordless phone can deal with (Uniden claim that their bluetooth hookup is only compatible with version 2.0). I have heard of others with this problem when trying to hook up to their car bluetooth eg. GM only supports connections with devices running up to Bluetooth version 2.0.
Given the above - what I am now looking for is a way to dumb my bluetooth down to 2.0 from the current 2.1 spec it seems to be running. Has anyone managed to achieve this - perhaps through some sort of registry editing?
Cheers,
Scott

Noone answered this so I'll take a crack at it... 2.1 is backwards compatible, so it'll work. You need to figure out what profile the Uniden requires. Is it handsfree or headset? When you try to bond (pair) there are two things that'll fail it... wrong passcode or device accepting the pair NOT in discovery mode. Since I doubt it's the passcode, it must be the latter. I assume you're turning on the BT on the Uniden and having the TP2 discover it. It'll see it... but it won't pair. Turning on the BT doesn't put the device in discoverable (pairable if you will) mode.

Updating Bluetooth

Ik have a Sony Smartwatch. Before the Sony update to 1.2.37 it used to work very well with my HD. On Runnymix 4.0 and on Icecream Sandwitch 8.3/8.4. After the Sony Update no more pairing with bluetooth. I figured out that the HD has bluetooth version 2.1, and that the Smartwatch has 4.0( not confirmed).
Is it possible to update the bluetooth radio voor the HD?
Some of my coworkers also have a HD, some even stock(!) No pairing whatsoever .....
My Nexus S on Jelly recognizes the Smartwatch an works with it.
But i want it on my HD!

Jellytime rom for hd is working great. that may pair with your watch? also, flash the latest radio? for me, bluetooth pairs in under a second with my car radio and other devices.

60.
Would you be so kind to tell me wat kernel you have? I am on radio 12.68.60.29u_26.16.09_m04.
My kernel is: 2.6.35.14 aospX
I googled out that Nexus S has bluetooth 3.0. Perhaps that is the issue because the custom roms are still on 2.1.

Nope, installing Jellytime didn't do the trick. Have to wait for the 3.o kernel...

Bluetooth version & BMW music streaming

I wondered if anyone can help with my query regarding getting music streaming to a BMW 320ED via Bluetooth?
The good news is that I can get my Galaxy Nexus (GSM 4.1.1 stock software) to pair with the car and I can get music playing via Bluetooth, but I can't see the artist information. The car screen informs me that the device doesn't supporting sending track information, or something along those lines.
What frustrates me about this is that my friends iPhone 4S does stream the track information as well as the actual audio. I Googled to see what Bluetooth version both phones use, apparently the iPhone 4S is Bluetooth 4.0 and the Galaxy Nexus has 4.0 capable hardware but only 3.0 features are available due to software limitations.
Is this true? Is once of the differences between Bluetooth 3.0 and 4.0 the ability for track information to also be shared? I was using Google Play Music if that makes any difference.

I've done some more research about this and thought I would update my post, just in case it's of help to anyone facing a similar issue. Turns out the Bluetooth protocol/profile AVRCP is responsible for streaming music tags to the car stereo, but only AVRCP 1.3 and above. Unfortunately the Galaxy Nexus only supports 1.0 by default but CyanogenMod 10 has built in support for 1.3 since roughly the 14th September nightly.
Should be able to test it out next week at some point. Why are Google so bad at supporting the latest Bluetooth features? I've always found this with Google experience devices to lack in this area where other manufacturers support the latest Bluetooth features.

[Q] Polar H7 Bluetooth 4.0 BLE on stock firmware

Has anyone tried pairing one of these to the OG? I know BLE is in the specs of the phone, but theres conflicting reports about google supporting this. I know from searching that this does not work on the Nexus 4 on its stock firmware but am hoping the LG has baked it into their stock 4.1.2
