IMO, 'nothing for T:C' is not an option.
*[Kim] Does it mean Tizen:common is mandatory for Tizen 3.0?*

Hi Kim,
Thanks for you to pay attention to the status of NTB.
The following points are my answer.
1. Is NTB decided to be in Tizen:IVI?
To my knowledge, In the plan of IVI, NTB will be used. At current,
NTB can’t be used for Tizen;IVI in Tizen 3.0.
We are trying to fix the related issues of Tizen:IVI in Tizen3.0. So
that NTB can be accepted for Tizen;IVI in Tizen 3.0.
*[Kim] From Mikko's thread, it will not be included in the next IVI
release.*
*IVI 14.4 is targeted to be released soon. As time is limited, IVI
14.4 will not adopt NTB. But in the long run, NTB will keep readiness
for active profiles, including but not limited to IVI.*
2. Is NTB planning to be in Tizen:common?
1. To my knowledge, In the plan of Tizen:Common, NTB will be used.
However, at current, NTB can’t be enabled in Tizen:Common.
You have suggested that NTB will be merged to
platform/core/api/bluetooth with a Marco to split the current
bluetooth package and NTB. We think that it is feasible solution for
dual stack. We will accept the solution. (Thanks for your suggestion).
*[Kim] We first have suggested this, but Martin did not agree on this
suggestion. Can you please check this?*
*I have talked the topic with Martin. The suggestion can be accepted.*
2. Therefore, NTB will be merged to platform/core/api/bluetooth with a
Marco to implement dual stack.
*[Kim] I think it would be better to merge NTB after confirming Tizen
bluetooth****direction and deciding to be in IVI release.*
*For Tizen Bluetooth, we think we (Intel and Samsung team) discussed
this lots of times in the past. To me, the goal is to have an unified
solution to provide better support to different profiles and emerging
features. The initiative we are working on NTB is to solve problems
like we need more simple Bluetooth-Frwk design and support multi-user
mode and so on. We don’t think NTB is already perfect and fully
error-free, but, as the design goal describes, it could help to solve
some real problems we are facing today. *
*For NTB integration, we think it’s the appropriate time to do this so
in Tizen 3.0 we have more flexibility to adapt to different requests.
Also, please note we have taken long time to do stabilize work and
pass TCT test, so NTB is ready now.***
*At the same time, according to our plan and NTB integration
solution(we**(Intel and Samsung team)**have discussed it for a long
time), NTB should be merged at this time to match the related
milestone in our plan too.*
3. At current, the Marco will not be default enabled. Therefore, NTB
will not be enabled in Tizen Branch too. It will not impact any
feature and platform.
We will continue to develop NTB in platform/core/api/bluetooth to
match the related requirements.
After matching the related requirements, the Marco will be default
enabled and NTB will be default enabled in Tizen branch too.
*[Kim] If it will not be used for next Tizen:IVI release, I don't
think NTB code need to be merged in Tizen branch.I think developing in
devel branch is more rational until NTB is decided to be included in
Tizen:IVI release (or other profile release). At that time, we can
tell Tizen bluetooth is supporting dual stack, isn't it?*
*As I mentioned earlier, the target of NTB is not to provide dedicated
support to IVI or specific profile only, so I can’t see any reason to
narrow/bind NTB usage with a specific profile.*
Any suggestion? Thanks.
Best Regards
Zheng Wu

Dear Mr. Zheng Wu,
As we already know, bluetooth for Tizen 3.0 is agreed to be dual
stack(bluetooth-frwk/NTB) architecture. I have several questions
regarding this. Would you please give your opinion about below questions?
1. Is NTB decided to be in Tizen:IVI?
I could see some reported issues regarding IVI NTB at
[email protected] <mailto:[email protected]>. So, I want to know
Intel has confirmed to use NTB for TIzen:IVI in Tizen 3.0.
2. Is NTB planning to be in Tizen:common?
From "[Dev] NTB-0.3 has released", I could see "NTB-3.0 has been
release and is ready for integration into Tizen-3.0 common". However,
NTB is not currently supporting mobile profile as well as wearable
profile, so I think it cannot be Tizen:common (please refer
https://wiki.tizen.org/wiki/Common). In my opinion, bluetooth-frwk for
Tizen:mobile, NTB for Tizen:IVI, and nothing for Tizen:common are
appropriate solution for the dual stack because no stack is supporting
every profile (e.g., mobile, IVI, wearable, etc.).
Based on your answer, I will suggest the specific plan for bluetooth
dual stack such as git repository, branch, etc.
Regards,
Seungku
