Android 4.2 JB MR1 Bluetooth

[Pavan Savoy]

Hello Google Gurus,

I see that BT on 4.2 JB MR has introduced a new stack called bluedroid, and understand a lot of code is from broadcom, So I have these basic questions :-

1. Is bluedroid the way forward ? Or will the vendors have option to switch to BlueZ ? 

I see even packages/apps/Bluetooth.apk JNI only looks up to bluetooth.default (i.e bluedroid) & NOT to legacy libbluedroid (system/bluetooth) - Why ?

2. Why was the decision taken to move away from BlueZ ?

Is the decision technical ? What is that which you found in BRCM stack which was missing in BlueZ?

Previously there were strong suggestions NOT to have proprietary stacks for technologies since they introduce a LOT of fragmentation in Android - Which I am guessing Google guys don't want.

3. Seeing that no new APIs have been introduced, nor the framework seems to be updated, Any plans for BLE in near future ?

Or new profiles.

4. Please let us know if there is any documentation for platform developers to port this stack to rest of the world BT vendors.

i.e What are the basic implementation required for 

libbt-vendor.so ?

If we get most profiles working in 2 functions (op BT_VND_OP_POWER_CTRL & faking success BT_VND_OP_FW_CFG) Is that good enough ?

As far as #1 is concerned, the details are in the CDD. Some modules
must be used unchanged by vendors in order for the resulting device be
compatible, others can be modified as long as they implement all the
documented behaviors of the public APIs. I'm guessing that BT might
fall in the second category, but I'm not authoritative in that domain.

Hi All and JBQ,

I quickly surf the Bluedroid source code which is released under "Apache License, Version 2.0 ".

I see SBC audio codec is integrated as a default A2DP Bluetooth codec, but is there any restriction to integrate other Vendor Specific A2DP codecs as part of A2DP profile in Bluedroid?

Many thanks,

Ash

Matthew, Can you help answer the rest of questions?

I will answer the questions as I can.

We don't have resource to maintain both Bluedroid stack and bluez stack. Blue support is stopped after 4.2.

BLE will be the next major feature we are going to add.

Other a2dp codec can be added. We only implemented SBC because it's mandatory.

Vendor need to implement bt_vendor_interface_t. The interface defines the way vendor lib and bluetooth stack interact to bring up and config the Bluetooth Controller. The defintion is in external/bluetooth/bluedroid/hci/include/bt_vendor_lib.h.

We don't have other document, it all in the code, fully open-source.  Please see bt_vendor_lib.h on the meanings of the opcode, such as BT_VND_OP_POWER_CTRL. 

device/common/libbt/src/bt_vendor_brcm.c contains broadcom implementation of vendor lib.

hardware/qcom/bt/libbt-vendor/src/bt_vendor_qcom.c contains qualcomm implementation of vendor lib.

Thanks

Any ETA on this? Will it make it for the next Android major release? (~6
months), or are you planning on a shorter release cycle for this?

Hi Manuel

I don't have more info on the BLE schedule at this time.

JNI is also at packages/apps/Bluetooth/ - But adding new APIs would be more to do with frameworks I suppose.

Matthew,

1 question among those I felt unanswered - Why was the move made ?

Wasn't it Android's ideology, philosophy to go with open source, community developed and maintained projects ?

Hello Mathiew:

I just received my Nexus 7 4.2JB device and it has pins on the side.

Either these are battery charging pins or they are some sort of JTAG port or they are related to the antenna/usb?

Could you confirm this in any way?

If they are charging pins, is there a way to get an intent fired in an APP when the POGO pins are charging or discharging?

If they are USB or Antenna pins, how can I use them?

Cheers,

Marco

Hi Matthew. Thanks for your candid answer. That BLE has (finally!) percolated up is indeed good news!

We can understand that you as a developer may not know the release date. But there must (or should) be somebody inside Google that knows. 

We would like that person to speak up. Please ask your manager to speak up, or have them contact me. I need to know how many tens of thousands

of iPhones I will have to buy to use before I can start using Android in medical apps (actually its' more like tens than thousands, but that's just for

the little  research group I work in; worldwide, the number of iPhone/iPad sales that are being made merely because Google dropped the ball on BLE 

probably *is* in the tens of thousands ... per month).  And everytime somebody starts up a new project, the number goes up. AND THESE PEOPLE 

WILL NEVER COME BACK TO ANDROID.

Please, have your manager speak up, or contact me by email (Google knows it).

Thank you.

The fact that Android introduced bluedroid stack with 4.2 MR1 Jelly Bean pretty much suggests there is NO point in asking Google for road maps anymore (at least in bluetooth and nfc anymore...)

Android project was a good amalgamation of open source projects whose road map was determined by community PREVIOUSLY.

So, the question itself is asked to wrong people in a wrong forum !!!

know anyone in broadcom ? :)

BLE is the new Bluetooth stack in Android 4.2 ?

If so, is it any better than previous community-built Bluetooth stack, BlueZ ?

No, it isn't. Please go back and re-read the original thread.

Android 4.2MR1 includes a replacement for the conventional Bluetooth stack,
coincidentally written by Broadcom.

BLE is Bluetooth Low Energy, a.k.a. BT Smart, part of Bluetooth 4.0.

BLE is one of the holy grails of people in industries like Healthcare,
b/c you can run
a tiny medical monitoring device for weeks or months w/o recharging or
replacing its battery,
instead of hours or days.

Many current generation Android handsets have the hardware (many of them
Broadcom
dual-mode chips) that can do BLE, but there is NO SUPPORT in software.

That is why the iPhone is totally creaming Android in the healthcare
market. Google knows
this and doesn't care, or they would put more resources on the case of
getting it finished (see the OP's
comments about not having resources). See, Google isn't about selling
handsets, they are about
placing advertising in front of people. My evil conspiracy theory is
that Google doesn't care about
healthcare because they know hospital administrators won't allow ads in
medical aps. Could it be?
Nahhhh. More likely they just forgot about it. Which is worse?

[dinesh shan]

Hi Google,

 

Do add the support for Smart Bluetooth.

I would like to stick to Android and not take up iOS for this simple reason of BLE support.

Kindly get the BLE api's asap.

[Chih-Wei Huang]

Hello Matthew,
Could you list all the steps to enable Bluetooth in JB-MR1?
I'm struggling with it without luck. I guess it includes

* Kernel driver?
* BoardConfig.mk parameters?
* bdroid_buildcfg.h ? What does it intend to do?
* bt_vendor.conf ?
* any others?

I think we are all jaded because of bad experience of Nexus Bluetooth, but Google is now serious about Bluetooth because Glass uses Bluetooth.  And according to FCC, Glass's Bluetooth includes BLE, so the new desire to make Bluetooth work on Nexus should extend to BLE too.

So, I'm still betting that we see BLE at I/O.

i.e What are the basic implementation required for 

libbt-vendor.so ?

If we get most profiles working in 2 functions (op BT_VND_OP_POWER_CTRL & faking success BT_VND_OP_FW_CFG) Is that good enough ?

Hi,

One question about Bluedroid HCI debug.

I found that there should have an external HCI logger which can parse all HCI log like hcidump do in Bluez.

Does any body know where I can get this external HCI logger/parser ?

Currently I can only dump the HCI log into binary format:(

i want that how many devices that can pair using Bluetooth in android?

[Jayantakumar Singh Konjengbam]

This connection limitation is not platform specific but BT protocol specific. The LT_ADDR used is 3 bits in size (last known in 2.1 spec), which allows you to have a maximum of 7 devices connect to your device. Please confirm with the latest spec.

As far as BlueDroid is concerned and adoption of this BRCM stack, I believe OEMs want to be Bluetooth Smart Ready. I don’t think BlueZ used in Android is BLE conscious even.

 

Regards,

Jayanta

That's a wild statement... Bluez supports BLE from 4.89 version onwards while Android 4.1 uses 4.93.. it was only the android support for BLE which was missing ...

Hi,

I want to know profile version which are supported in Bluedroid.
example -  A2DP 1.2 or A2DP 1.3.
It will be good if  i can get information for all the profiles which are supported in Bluedroid.

I could not find a qualification from Google at the Bluetooth SIG web pages, yet.

Hi all, 

I would like to know whether someone have CSR vendor library extensions (libbt-hci,libbt-vendor) for Bluedroid stack? My development hardware has CSR8811 chipset and I would like to get it up and running with Broadcom's Bluedroid stack.

@Pavan - I see the approach of TI support for Wilink chipsets. Can similar work be done even for CSR?

Regards,

Sunil
