SGSII and bluetooth - Galaxy S II Q&A, Help & Troubleshooting

I have a weird problem with my SGSII. If i connect my phone to my car bluetooth with the car charger, it stay connected for as long as I am in the car. If however i connect to the car on battery, once the screen turns off I lose bluetooth connect. I have tried changing the screen time and that didn't work, I also tried making my bluetooth visable always and that also didn't work. Can't understand why it only happens while on battery.
Any suggestions?

I have the same issue with bluetooth on my SII.
Whenever the screen is asleep bluetooth devices will not connect, I have to turn the screen on to allow the devices to connect.
I've setup auto pairing in the linkkeys file which works fine if the screen is on (so no prompts to pair devices, just works).
The main device I want to use is a liveview, which I understand has problems, but I've tested other devices and the phone seems to be at fault.
It can't be designed that bluetooth will only connect if your using your phone, kinda defeats the purpose of most bt devices.
tried making my phone always visible, and even tried disabling the lock screens.
using CM7 stable, and a fix would be highly appreciated!

Hmmm.... I don't have that problem.
Maybe some weird power save option?

that's what I was thinking, but I've not been able to find any settings on the phone or through google.
I've just updated to the latest cm7 nightly and the problem seems to be the same. It has an addition bluetooth setting called 'Fast Connections' but this doesn't seem to change anything.
The only other thing I've noticed is that the linkkeys file that I edited to allow the liveview to auto pair (without me having to pull down the notification bar nad authorise it) seems to keep re-editing the file so the phone prompts to pair, so I'm assuming now that's the issue rather than a power thing, so how to prevent that?

Can not activate Bluetooth

Since two days I got the problem, that I can not activate Bluetooth anymore. On the settings "Wireless & network setting" I press the Bluetooth activation (Turn on Bluethooth). The status changes to "Turning on ... " for about 10 seconds, but doesn't turn on. Before was working fine, I do not remember to have something deleted.
It seems to me, as if Bluetooth is switched off (or disabled) by some application.
Would like to isolate the problem. Any ideas how I can find out.

Do you have anything frozen through titanium backup? Have you installed any apps that use Bluetooth? I had an issue with car home locking my Bluetooth up when I undocked it. Telling Car home to turnoff Bluetooth once disconnected fixed mine. If all else fails and you cant figure it out, I would try flashing back to 1.57 and then OTA update it back to 1.83. Last resort of course so you don't have to set your phone back up, titanium backup can make this process easier.
If nothing works then may be a hardware issue. Best of luck.
Just wait before you get into it, another person may have better advice!

Hi. I installed a Bluetooth Transfer app. This was the reason, why I found out that Bluetooth wasn't working anymore. But I know for sure that Bluethooth was running fine, just a few days ago.
I really would like to find the reason, quite sure there is a software reason, and defenitly do not want to flash back.

X10 Bluetooth issues

Hi all,
I'm having weird bluetooth issue. if I connect headset voice call then it stay connected all day but if use it music stream then it shutdown after 10-15 min automatically. I'm stock ROM 2.1A.0.435 Baseband 2.1.54
i have this problem with 2.2 roms and ewjet roms. something with froyo sources. never seens this on any 2.1 roms other than ewjets, but i've never used a stock 2.1 after .492
you can try changing some settings at /system/etc/bluetooth(may also be bluez)/audio.conf
lines you can try changing is:
Code:
Enable=Sink,Control
Disable=Headset,Gateway,Source
try changing to
Code:
Enable=Sink,Control,Headset,Gateway,Source
#Disable
and
Code:
#AutoConnect=True
try changing to
Code:
AutoConnect=True
i've had mixed results with doing this, but i know it's worked on samsung devices. so who knows if it will work for you or not. what i ended up doing is this:
delete the pair
turn off bluetooth and the device
turn on bluetooth and put the device in pairing mode
pair them
turn off the device, but leave bluetooth on
go to settings>wireless>bluetooth settings
longpress the device and go to options
untick "phone"
turn on the device and let them connect
wait a few seconds and retick "phone"
it should work after that
however, everytime you disconnect, you will need to untick "phone" after you disconnect and retick after you reconnect. you may also get a cut in audio every 45 seconds or so. it's annoying, but it's the only way i can listen to music while i drive.

This happening with all bluetooth device mw600, my car stereo steaming

[Q] How do I get Bluetooth to connect automatically?

Running ICScrewed 2.0.1 and I've been running into a problem over the last few roms I've flashed where my Bluetooth doesn't auto connect.
I have a Jabra Cruzer 2 bluetooth speaker in my car that I've paired with my phone. Tasker is setup to start a menu system when the bluetooth connection is established....but it never happens. I have to go into the BT menu and press on the Jabra device to make it connect. By default it shows "Paired" so I press it and it changes to "Connected".
I know when I had UnNamed previously it was auto connecting everytime I would jump in my car and hit the connect button on the Jabra. It hasn't worked that way since I've gone away from UnNamed. I even tried going back to it and now it doesn't work.
I've checked the Jabra and there's nothing to the settings so I'm 99% sure it has nothing to do with the device.
Does anyone know of a place to tell it auto connect when detected?
Followup question,
I also can't get phone calls to go over the bluetooth device either. Is there special place to look to make sure calls go over bluetooth by default?
Thanks everyone for your responses.
You may have to re pair the device. Did you restore bt pairings when you changed ROMs? That can cause no end to problems, especially when they are different bases.
I have the same Jabra and it connects every time I press the talk/end button on the unit.
Sent from my SGH-I777 using XDA App
I may have somewhere along the line Titaniumed the BT pairing back. But my most recent flash of ICScrewed was preceded by wiping dalvick, clear cache partition, and wipe before installing full. So I'm not sure how anything would have come over unless there was a folder somewhere with bad data.
Is there a folder I should clear out and pair from scratch?

Dead WIFI on android 4.0.1

I have a 4.0.1 device (car stereo actually, I could post to that thread, but here I will probably pass with more attention).
WIFI sometimes works and sometimes doesn't - I simply can't turn it on.
It stucks at "Wifi turning on" and switch goes back to gray.
When it works it works for few days, and when it doesn't I can't turn it on for like a month. Right now that's the case.
WIFI device is an external USB wifi stick. Stick works elsewhere, and I tried with another one, they both work.
I believe the problem is in the software.
On some devices it can be solved via deleting some files in the system. Has anybody got some ideas how to fix it?
Usually when it works stick LED starts flashing right at boot.
Regular data usb stick also works in that port.

Pixel 2 non-functioning screen, options for using ADB?

Greetings fellow techno-wizards! Got a big problem that I'm hoping you can help me with.
Long story short, my trusty Pixel 2 had one too many drops, now the screen won't turn on and won't respond to touch. The logic board is operating, and I haven't rebooted since then, so I can unlock with the fingerprint sensor.
I plan on getting an Pixel 5 when it releases, and have an LTE Tablet to limp along until then.
My biggest problem is authenticators on my phone that I may or maynot have the backup QR code for, as well as many other things I'd like to get off the phone before I retire it.
I have the following things at my disposal:
Pixel 2, with USB Debugging turned on, and recently trusted the PC. No screen, no touchscreen.
WearOS watch paired to phone (can get notifications and texts)
Bluetooth Mouse
Wired mouse with USB to USB C adapter
Chromecast
Win PC with Scrcpy installed, already tried to use it to show the screen on the PC, I'm guessing its been too long and I have to press a notification to trust the PC.
The Goal:
To cast the screen to a chromecast and pair a bluetooth mouse, and/or get Scrcpy working by accepting the dialog that I can't see. This would allow me to use the migrate tool to the new phone I will eventually get.
I tried long ago to use a USB C to HDMI adapter, that doesn't work. Google wants you to use a Chromecast for such things (Thanks a ton Google )
The thing I need to figure out next is how to use ADB to force the phone to start casting to a Chromecast, or to remotely accept the dialog. The wired mouse with adapter should work to control the phone instead of the touchscreen, but without any video out, I'm clicking blindly. The microphones are working, but I've never tried to command the assistant to start casting before.
Can anyone suggest the next step I should try?
Just had a thought, there are accessibility features for blind people that would let them use the screen without seeing it. Is there any ADB command to enable these features? If I plug in a keyboard, is there a keystroke combination to turn them on?

Since you say ADB is enabled on the phone you should be able to pull out by means of ADB-driver the data in mind to your Windows computer.
