[Q] Can not Bluetooth pair iPad 2 ios 5.1.1 with Android 4.0.3 using BTStack 1.6.3 - Android Software/Hacking General [Developers Only]

Devices and SW: iPad 2 ios 5.1.1 jailbroken, Galaxy s2 GT-I9100 Android 4.0.3, latest BTstackGPS 1.6.3 installed from Cydia.
Followed instructions: On iPad turn off ios BT and set BTstack as active stack. Turn on BTstackGPS.
Initiated pairing from the phone using the regular BT pairing procedure (which worked with other devices). The phone recognizes iPad and iPad recognizes the phone.
All pairing attempts failed !!! Some attempts prompted to enter a 4 digit code and some didn't even do that.
Point: When a pairing attempts were started from the phone, BTstackGPS on the iPad was turned off automatically (At least the screen changed to the home screen and I had to press the BTstakGPS icon again)
I also tried initiating the pairing from BTstackGPS. No success.
iPad (and other ios devices) in general can not pair with Android devices, but BTstack is supposed to resolve it.
There are testimonies of people that they were able to pair with older versions of ios and Android.
Any clues????????????????????????

[Q] Trouble with bluetooth input devices N8000 on official 4.4.2 update

I have applied the official 4.4.2 update to my Note 10.1 (N8000) using heimdall (as I did not have the over the air update yet). The software updated flawlessly and I do not seem to have any problems in that regards.
I am having trouble with bluetooth input devices. I have tried two keyboards (one unbranded and one Kensington) and a Penclic bluetooth pen mouse. All devices pair and are marked as connected, however the input is never accepted. In case of attaching the keyboard, it even is the case that the on screen keyboard won't pop up anymore. Also in the logcat I see that the devices are connected and recognized as input devices.
Some googling revealed that in general there are complaints about input devices with android > 4.2, however I am hoping that somebody has some idea or pointers on how to solve this (or where to look) specifically on this device.

[Q] Bluetooth always fails with sending files

I don't know why is this happening. I can't send files to others or to my laptop because every single time it keeps failing, even despite pairing the devices.
This has been happening with every single android phone I owned (HTC HD2, Galaxy Nexus, and now Nexus 5). What am I doing wrong?
EDIT: I just checked and it doesn't even discover the laptop while the laptop can discover my N5. Of course, visibility is set to "on" on both devices.

[Paranoid Android] My Phone won't connect to my Moto 360

Yesterday my One wouldn't boot up so I figured this would be the time to try out Paranoid Android. After flashing and restoring all of my apps and data, I went to open Android Wear and connect to my watch. My phone will connect, but not the Android Wear app? When I start to connect, my phone and watch get a Pair message and I choose pair, my Android Wear app won't connect to my watch although when I go to the Bluetooth menu on my phone it says connected.
But It doesn't say connected on my watch either.
Could anyone help me? My Moto 360 is on Android Wear 4.4W2 and my phone is on Paranoid Android 4.6 Beta 5
Thanks.
Look what you are running
I got moto 360 and OnePlus One and I think it is because the beta build is not supported.

Wear OS watch doesn´t connect to Xiaomi Mi 8

Hi everybody!
I have a Ticwatch E that I'm trying to pair with my new Xiaomi Mi 8, I've been trying for 3 days and I still cannot pair it. This are the steps I execute to pair it:
I open the Wear OS app in my phone
I look for devices and my watch appears
I click on my watch in the device list
(Here comes the problem )
A PIN is shown in my watch, it should be shown in my phone too but it doesn´t. My phone says 'A prompt to connect will appear on this phone' but nothing happens.
After a few seconds of waiting, my phone says "Couldn´t pair with Ticwatch E 299 N, because of an incorrect PIN or passkey"
At first I thought it was a problem with the watch, since my brother has a Ticwatch E and a Xiaomi Mi 8 too and he could make it work in the first attempt, so I tried to pair my watch with his old Samsung Galaxy S7 AND IT WORKED!
After that I tried again the same steps as described at the beginning of the thread with no success, so I proceeded to try connecting it without the Wear OS app. I went to Settiongs -> Bluetooth -> Selected 'Ticwatch E 299 N', and the PIN to connect was showing both on my watch and my phone, I hit 'Pair' and then it got connected. The problem is that my watch says that I should continue the configuration process in my phone but there's no configuration process if I don't pair it with the Wear OS app.
Other things I tried:
- Downloading the Mobvoi app and trying to pair from there (it asks me to open Wear OS, so it's basically the same).
- Downloading multiple old Wear OS versions in my phone and trying to pair using them (none of them worked)
- Following this steps after having paired it to my brother's old phone and then trying to pair it with the Wear OS app (This time the wear showed the PIN and asked me if the PIN was the same that was being shown in the phone (no PIN was being shown in the phone), so I clicked Yes and then I got the same 'Incorrect PIN or passkey' error message)
- Deleting all the data (including cache) of Google Play Services, Google, Wear OS, Mobvoi app, Bluetooth/WiFi/Mobile Data connections, and then rebooting the phone multiple times (no success here too)
P.S.: I did a factory reset of the phone before every mentioned attempt.
More info about my watch versions:
Home App: 2.8.0.183948193
Google Play Services: 12.2.21
Android OS: 8.0.0
Security Patch: August 1st 2018
Info about my brother's watch versions:
Wear OS by Google: 2.6 (I don't know why I don't have this in my 'versions' section)
Home App: 2.22.0.234791771
Google Play Services: 15.0.90
Android OS: 8.0.0
Security Patch: August 1st 2018
As you can see there's a clear difference between the versions of each watch, I would like to update my watch to my brother's versions but I couldn't find how to do that without rooting the watch (I'd prefeer to keep it unrooted if possible).
Any idea of what could I do to solve this? My phone's bluetooth works fine (I can use other bluetooth devices such as headphones or a JBL Charge 3, this is the first one that didn't work) and my Ticwatch works fine too (I could make it work with the S7 )
UPDATE: I connected the watch to the Samsung S7, updated Wear OS and now all the versions of both phones are the same (except for the Google Play Services version, I couldn't update it), it still doesn't pair.

Lenovo Tab 2 A10-70F with Carlinkit Carplay dongle--problem

My Lenovo Tab 2 (6.0 Marshmellow stock, unlocked, not rooted) refuses to work with my latest acquisition (Carlinkit Carplay dongle from Aliexpress). The wired plus wireless dongle works on any android above 4.0 and I've tested it on phones from Android 5 to 7 without a problem.
However with my Tab 2 (which I was going to install in my car as a handsfree and navigation unit paired with my phone), it simply refuses. One has to install an app called Autokit (address on vendor's page in Aliexpress) on Android device. When I connect my phone via wireless, it attempts many times and either fails and starts all over, or the screen goes blank (with phone saying it's in carplay mode), or gives warning "The navigation machine [i.e. my tablet] does not support current settings. Please disconnect your phone and enter the Settings page to enter compatible mode."
In settings page I have three "working modes"--speed, fluency and compatible. I understand them to be resolutions: full HD, HD and lesser (VGA?). I get this message on both speed and fluency. In compatible mode, I briefly see the screen loading before it hangs and disconnects.
If I attach phone with dongle with a cable, the app does not react at all and still goes on wifi and blueooth looking for a device.
However in other phones I've tested on, I've had no problem with either of the three modes, or cable phone-to-dongle connect.
Questions:
1. Is it possible to upgrade/ change settings on Lenovo Tab 2 to accept my dongle or is it a lost cause?
2. I understand the dongle has its own wifi and bluetooth, and doesn't rely on cable. Therefore, it must be some USB protocol in the tab which is causing difficulties (as dongle works fine on other phones). Is this logical?
3. If so, there ought to be a better way than disposing my trusty Tab 2 and shopping for a used tab which will accept my dongle?
Thanks.
