Hello,
Currently, I am working on Bluetooth Low Energy (BLE) remote with my company.
We would connect our remote with a Google Nexus 7 tablet using BLE.
We searched few information concerning data frequency reception but we did not found good answers.
Question :
- Is 100Hz data frequency supported by BLE Android ?
- If yes, what is the maximum payload we could send ? We would like to send 14 data in our payload.
Thank you in advance for your answer.
Best regards.

Does Android 4.1 allow a device to serve as a Hands-Free Profile (HFP) device? Similar to the way many newer cars come with integrated Bluetooth/HFP, I would like to use my tablet (Nexus 7) as a front-end for my phone. When an incoming call comes in, the phone should relay the call over Bluetooth to the tablet; it should also allow the tablet to make outgoing calls via Bluetooth over the phone's network.
Please note that I am not interested in solutions such as GrooveIP, Talkatone, and SIPDroid. I am specifically looking for Bluetooth HFP.
I've done quite a bit of searching but have not seen an app that does this. I wouldn't mind looking into developing such a product - but I first wanted to know if the HSP 1.6 host API was available in Android 4.1. I've seen resources stating it was available in ICS 4.0, but I believe this is to allow Android devices to connect to third-party HSP devices - I'm looking to do the opposite (i.e. have the Android device serve as the HSP host).
i am also curious about this.

Me too
For those of us that plans to install a Android tablet in the car for music etc. this would be tha last part to make it a complete in-car device.
I am another curious one about this. The only devices I know of for sure that can do this are the 3.6 and 4.2 samsung galaxy players. Unfortunately, I have the 4.0 galaxy player, that doesn't support it. The galaxy players run gb, not jb, btw.

Did anybody found a solution, and trying to add this feature to my android app.

From what I can gather:
* Bluetooth defines HFP to have two roles: the Audio Gateway (AG) role and the Hands-Free (HF) role.
* Android doesn't natively support the HF role.
I too am interested in exactly what you are describing -- would like to use a tablet as the infotainment hub of a vehicle. I would happy to be a part of or organize a bounty to support development of such a capability in CM10.

Someone custom-implemented the needed Bluetooth role
Looks like some Android device has custom implementations of both A2DP sink role and hands free unit role. I can't post links yet. Google this:

any leads if this is available on android yet? (Hands free profile)
There's some development about this but I'm not sure it's possible yet.
have a look at the links here: https://stackoverflow.com/questions...a-receiver-for-a2dp-profile/28892944#28892944
I want, too
to use android device as hands free
Hello !
I have an "old" HTC Incredible S but with an Android 4.4.2 ROM .
Today I have bought Heart Rate Sensor for running but that use Bluetooth Smart technology. My phone can't find BLE (bluetooth low energy) sensor
So, I have some questions :
- Why my phone doesn't support BLE even if I run on Android 4.4.2 ?
- Is there solution to implement BLE libraries in ROM?
- Is there another solution ?
Thank you !
Hi,
Its proving hard to find a definitive answer anywhere on this, but can anyone confirm if the Z2 is definitely compatible with the Jawbone Up24 for example?
The Up24 requires Bluetooth Smart / LE (low Energy) which, as I understand it, is one of the Bluetooth 4.0 profiles.
Their website does say it is compatible with the Z1, but no mention of the Z2 or Z3. I would assume it is I suppose, but I find it strange nobody seems to actually say so, anywhere that I can find.
Any of the phone specs I've read say "v4.0, A2DP, apt-X" or "Object Push Profile (OPP)"
Also, in a Sony whitepaper, I see the following:
Bluetooth® profiles supported:
Advanced Audio Distribution Profile v1.2
Audio/Video Remote Control Profile v1.3
Device Identification Profile v1.3
Generic Attribute Profile Client/Server over LE
Handsfree Profile v1.6 (Wide band speech)
Headset Profile v1.2
Health Device Profile v1.1
HID over GATT Profile v1.0
Human Interface Device Profile, Host role v1.1
Messaging Access Profile v1.0
Object Push Profile v1.1
Personal Area Networking Profile v1.0
Phonebook Access Profile v1.1
Serial Port Profile v1.1
Core version and supported core features:
Version 4.0
Bluetooth Low Energy

So, anyone got them working together?
Thanks.
Nobody?
ok, well, for anyone who is interested, I just noticed Garmin are listing the Z2 as compatible with their Bluetooth Smart (BTLE) products.
That's enough for me.

Hi Everyone!
I'm thinking of purchasing a Samsung Galaxy S5, but I have a question about its Broadcom BCM4354 MIMO 5G WiFi 802.11ac / Bluetooth 4.0 / FM Radio Module. An image of it can be found at this link, which I can't seem to post because I am a new user (i58.tinypic.com/9icnfb.png).
As you can see, there are two WLAN antennas (marked #3 and #4), but only one with the capability to run both BT / WiFi. I'm wondering -- does the existence of two antennas enable developers to simultaneously receive / send bluetooth packets while receiving / sending wifi packets? I found this SO post (stackoverflow.com/questions/15927208/iphone-programmatically-use-wifi-and-bluetooth-at-the-same-time) which describes a coexistence protocol implemented in most phones that prevent them from truly use wifi / bluetooth simultaneously without any coexistence limiting.
So my question is: On the Galaxy s5, which has two antenna (both with the capability to use WIFI, but only one with the capability to use Bluetooth), if i were to programmatically send data via bluetooth and then programmatically send data via wifi, would the phone auto-allocate to use both antennae? or would it simply use a coexistence sort of deal using one antenna? If the latter, is there anyway (through root / development) that I can enable the phone two use both antenna?
Sorry if this question is ill worded, let me know if you want me to clarify anything!
Thanks
Hopefully this is a simple yes it will or no it won't do it type of question
I want to make use of my Touchpad in my Camper Van specifically to connect it to a couple of battery monitors via Bluetooth e.g. to a Ctek 'battery sense' monitor
I think the monitors use Bluetooth Low Energy (BLE)
To date I have not had any success I have tried Nougat and Oreo they connect fine via Bluetooth to my phone so I know 'proper' bluetooth works' but not to these two BLE devices
I have not tried KitKat yet
Should it work if so which rom should I try?
Thanks

In my opinion this is not a question of the ROMs available for the HP Touchpad (at least not only). The main thing is, that the HP Touchpad is from 2011 and it's bluetooth specification is BT 2.1. That means, it supports bluetooth EDR in the best case, but no BLE because for bluetooth BLE you need newer chipsets. Bluetooth BLE have versions of 4.x, not 2.x.
