Any developers interested in tweaking this? - Android Q&A, Help & Troubleshooting

Alright, so the short version is that this app is supposed to be able to see Bluetooth devices, but when running with Android 10, it no longer is able to see Bluetooth devices. The app is old and I'm seriously betting it won't be updated and fixed for Android 10. Any developers interested in checking out just WHY this isn't able to detect Bluetooth devices in Android 10?
Longer explanation: this app is for the E-SYB E4 lithium battery charger. It's supposed to connect to the charger and show your battery voltages and allow you to change the charge speed and battery type and such. It just does NOT want to see Bluetooth devices when run with Android 10, and it's frustrating given that this charger is more expensive BECAUSE of this Bluetooth functionality. Any developers interested in checking out just WHY this isn't able to detect Bluetooth devices in Android 10?

[Q] Tablet as handsfree (HFP 1.6)?

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.

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

[Q] Why is ther no universal Bluetooth patch??

Could someone tell me why its impossible to find a universal Bluetooth patch for EXTERNAL usb Bluetooth dongles? One that will add the full Bluetooth feature to the devices "born" without build-in Bluetooth.
We are so many that bought these Android tablets thinking that we could just plug in a Bluetooth usb dongle - for why would that feature be missing in Android, bluetooth has been around for so many years even before anyone thought of android.
So why is this left out of the kernel, it should be as basic as Wi-Fi?
Come on XDA developers - make a universal driver, then get people to test it and add their devices to the list of working.
Doesn't bluetooth work in linux? And isn't Android based on linux?
So why is it so hard to make the driver/patch?
Or is it simply that most developers think that bluetooth is obsolete - So never mind?
With kind regards

[Q] Naive question about interfacing android phones with Windows PCs

OK, simple naive question. Most modern vehicles come with a touch screen system that can access Android phones via a bluetooth interface, initiate calls, receive calls, bring up the contacts list, display text messages, etc. I would like to implement this functionality with a Windows based PC.
I also know that Windows 7 and 8 have a limited method of interfacing with Android phones via bluetooth. If one wanted to emulate the features in modern car systems to pair and work with Android phones using a Windows based PC, what software/hardware options are available? The hardware seems to be only a working USB bluetooth adapter, but the only software option I have found to date is Blue Solei. Any other options?
Thanks!

[Q] Android built-in a old car

Hello! First sorry for my poor language.
Polish android forums can tell me only stupid ideas, these people can't use brains.
I want to open discussion about mounting smartphone with Android to car. Important things: considered connect charger(i have car electric items and idea how to connect and hide wiring), make car recorder(AutoGuard app), make audio source(bluetooth connected for car radio - without wiring), sometimes use Torque app(i have OBD 2 mini ELM adapter).
I have some old phone - Samsung SM-G350. Car is passat b5, but its not important.
My samsung is rooted, have cyanogenmod 11 on android 4.4.4. I'm searching ideas for reaction in my telephone when i turn on my engine. For example - if i turn engine on, car charger is working and callphone battery is loading. I want to in this moment run AutoGuard and start recording, or screen is displaying always and is unlocked.
Have some ideas? Maybe change android files? Some scripts? Help me, i need to good advices.
You need the Android Auto for that, old cars don't usually have it.
To have something mounted, your best option is to get an Android Auto receiver, but you'll have to do the research with your car info and stuff like that. You could also just get a simple phone mount for pretty cheap on an online store like Amazon.
With Tasker, possibly, you might be able to use that root capability to its potential by setting up some automation stuff that opens apps once the phone detects power input (once it is plugged in).
Android Auto is a good option, but I don't think that it runs on Android 4.4.4. You'll have to get something newer.
(I also just realized that this is a really old thread that people are responding to now. )

Do any Roms support BLE (Bluetooth Low Energy)?

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.
