[Q] Auto Bluetooth - Android Q&A, Help & Troubleshooting

Can anyone recommend me a FREE app that will automatically enable bluetooth when wifi disconnects and disable it when wifi reconnects.
Both me and my wife have bluetooth enabled phones, mine is a htc desire and hers is an X10 Mini
Our bluetooth kit in the car does not support multipoint so only one phone can connect at a time.
If either of us is by ourselves this is fine but when we are both in the car together its a crap shoot on which phone will connect.
manually checking bluetooth every time we get in the car is a pain in the butt and given the fact that I always drive when we are together I want to install an app to turn on her BT when her WIFI disconnects.
This solves the problem because if we are together my phone has already connected long before her BT ever gets enabled.

Have you tried "Setting Profiles". I can't remember what the free version does but certainly the paid for version (which isn't very much) enables you to do a whole lot of setting rules which would enable you to do exactly what you are wanting.
Give it a try. I've got some complex rules which detect cell locations and then trigger the enabling of WiFi when I get close to home and then when the WiFi is on another rule sets some other bits when I connect to my home WiFi.
Triggers can be, GPS location, Cell location, WiFi networks connected/disconnected, time of day, bluetooth connection etc. Very useful app. Good for power saving as well. (I've got a HTC Desire S but it should work on your phones as well).

Wifi auto connect

This seems to be a problem with android itself. Wifi never automatically connects to saved networks when in range.
I have to use an app called wifi fixer to monitor my wifi connection- it connects to a wifi network that I have saved when it is in range.
Below were my original questions I posted in the general section by mistake. After a lot of searching I found the folder organizer app can create short cuts to folder or categories for apps. So I can have a short cut in the launcher that goes to all my games, or utilities.
I haven't figured out how to make the cell radio being turned of be persistent. So I just have my device set to airplane mode- but when I reboot it I have to turn the wifi back on.

1. I'm on StreakDroid 1.6.0 and everything is gravy cept for WIFI not connecting automatically. That seems to be a problem with Android itself. For me it is a problem because I'm not using a dataplan because I get free wifi through my cable co. I'm using csipsimple with my old gizmo5 account that I bought with my n810.
2. Does any launcher do app draws? I'm using Launcher pro and it would be nice if I could put a folder in the dock to store all my games.
3. Anyone know if I can use 2 bluetooth controllers with this on emulators? I'm still waiting on my Datel classic wiimote but it would be awesome if I could use two controllers.
4. How do I remove the No Sim card message? I use this as a wifi device and I had it set to airplane mode for a while but then I found the app "any cut" and made a short cut to turn off the cell radio. Apparently if I have it set to airplane mode it turns off wifi by default- and I thought that was the reason why wifi doesn't connect automatically but I still have to manually initialize wifi. I have wifi set to never sleep btw*
5. Turning off the cell radio isn't a persistent setting it seems. Does the cell radio still use battery power if there's no sim card in the device?

Streak WIFI Issues
I am having the same problem. Running 2.2 with 318 baseband. Phone can find wifi but will not stay connected. Phone goes into an endless cycle of connecting and immediately disconnecting. I am able to get WIFI to work by putting the phone into airplane mode. Anyone have a fix??
Are you using the stock rom or dj_steve's? I've heard of people getting disconnected from wifi if the signal is weak. There's a way to turn of data on 3g under wireless settings. I believe that would prevent it from switching between 3g and wifi connections.
I don't really have this problem though. Once it connects to one of my saved networks it stays connected. It's just that android doesn't do this automatically when a saved network is in range.
WIFI Issues
I'm on stock rom. WIFI signal doesnt seem to be in the issue as I have been within 5 feet of the router and had the issue happen. I'm reluctant to turn 3G off as I need it on to make and receive calls in my house via Microcell.
You probably have to change that setting under wifi that puts the wifi radio to sleep when the screen turns off. I have mine set to never.
You may also want to run wifi fixer- which will automatically reconnect you when you get disconnected.
I'm going to try this:

Try rebooting your wireless router. I have 2 netgear wgr614's. One at home, the other at work. After several connect/disconnects, it goes in the connecting/disconnecting loop until I reboot the router. Go figure...
What I did that seems to have worked is to set up a static IP address instead of having the router assign it for me (DNS). Since then my Wifi connects every time. I could be wrong but it seems to have worked for me.

You mean DHCP not DNS. Mine always connects when tuurning wifi on but if left on and my streaks sleeps for an extended amount of time it will not connect till I turn wiring off then back on. I also have wifi sleep policy set to never. Had that issue with nexus one as well.

[Q] Optimus one Wifi issues - please advise

Hi guys, so here's the deal : Just got a brand new Optimus One and the Wifi dosen't really work. It took me ages to get it to detect my home network ( Realtek RTL8187, used as a hotspot via win7's wireless miniport adapter - so basically virtual hotspot) Once I managed to get a connection the device would either be stuck at "obtaining ip adress from..." or would simply disconnect and reconnect in a quick burst. I finally managed to get it to connect by manually assigning the internet sharing permissions for the virtual miniport, but the speed is abysmal! We're talking to the order of bytes/s, measured both by attempting a small download from the phone and by reading the in/out data on the pc connection info. Upon some further poking around, a few wifi adapter and phone restarts later, I notice that when I connect to my hotspot the phone's wifi manager reports a normal speed of 54mb/s, but when I actually try to use the connection (say, the youtube app) it works fine for a second or two (it usually loads a bit of a vid, or half of a big webpage) and then drops down to the aforementioned speed and the phone's wifi manager indicated that the connection is 2mb/s
Also, I went out before setting up my home network to a mall and tried to connect to one of the free hotspots available. On some, it would connect straight away, but be very slow (signal wasn't great) and on one (max signal) it would disconnect/reconnect in very short bursts (10-15 times a minute) and it would eventually establish the connection. Then the same speed issue as above: works fine for a few seconds, drops down to unusable. Didn't think about checking the connection speed there, simply thought the public network was overused. In hindsight, the problems were similar to the ones experienced at home
A few side notes: The 3g speed is fine, consistent and problem-free
I have tried changing my home wifi's frequency to a number of settings (there are quite a few other wifi's around, I know it could cause issues if they overlap)
My wifi connection was actually not detected by a friend's laptop wifi, but we could connect our computers just fine via ad-hoc (which from what I've heard is a no-go with android at the moment - and the phone does not see ad-hoc)
The phone is brand new, only installed a handfull of apps on it, didn't change any relevant settings (I think)
Set wifi sleep policy to "never"
My pc wireless adapter worked just fine in the past, used it for a few months as the main internet connection, and even with half-signal it would achieve good speed. I also moved the antenna away from the PC itself to avoid interference
I set my PC to use only 802.11b since I've read around that some phones prefer this to 802.11b/g
That's about all I can think of right now. (oh, and It's my first android, so I don't know my way around the OS that great yet)
I appreciate any advice you can give me. Basically I'm trying to find out if it's an issue with my Wifi adapter, it's settings, the phone's settings, or if the phone itself might be broken, so I can send it back to warranty.
Thanks in advance.
Try switching from b to g.
it was initially on b/g

Bluetooth and WIFI Coexistence issues

When I had my EVO 4G I had no WIFI issues at home or work. When I got the EVO 3D I had serious issues with WIFI (at home only) and I kept blaming the phone. Well after turning some options off (like turbo boost) and playing with bandwidth settings) EVO 3D became solid.
Now EVO 4G LTE is having WIFI issues. I had started a thread using 2.4Ghz for WIFI which was a huge help. But it's still not quite right. You can see it frequently flipping between WIFI and 3G. The phone again works fine at work. If I have to I'll buy the same wifi routers I have at work.
So I started digging into Router settings again and noticed this "WIFI Coexistence" option (which was set as disabled).
So I researched it on the dd-wrt.com web site (the open source I run on my router and found some interesting info).
I think this may have something to do with some folks issues.
It may also account for why some people say they have no problem and others do.
Even when you swap your phone your Bluetooth devices might choose a different channel when you pair it and have less conflicts. On old WIndows phones even when you unpaired it, it would cache the old channel and use it again if you repaired it.
I'm going try this option and try running with bluetooth off and see if it's more stable.
I have had bluetooth issues as well. Mainly after a call, the would disconnect from headset and headset could not reconnect without toggling bluetooth on the phone or headset (or both).
This is a copy of what I found on dd-wrt.com
==================================
I found a clear answer on TomatoUSB's website:
Bluetooth Coexistence
An 802.11 device and Bluetooth can interfere with each other when the 802.11 device operates on the 2.4 GHz band. All Bluetooth devices operate at the 2.4 GHz band. If you experience wireless disconnects, decreased range or speed, and other connectivity issues when you turn on some of your Bluetooth devices, try to change this option to "Enable" (this will make the router and Bluetooth device to take turns in using the spectrum for communication) or "Preemption" (the router will inform the Bluetooth device about the channel it is operating on, and the Bluetooth device can preemptively disable communication on the respective Bluetooth channels).
Please note that this option requires your Bluetooth device to "cooperate". If the Bluetooth device doesn't implement the coexistence techniques, using this option will have no effect.
I'm 99.99% sure it's bluetooth causes WIFI issues for me.
If your having WIFI issues (which interferes with 3G as well) and you normally keep bluetooth on.
Try as simple experiment leaving bluetooth off (I know you should not have to).
I left mine off today and data was flawless.
Switching between 3G and WIFI was instant and smooth.
When I wake it I see it jumping around between 3G and WIFI.
This phone uses a Qualcomm bluetooth stack and EVO 3D and EVO 4G used broadcomm.
I never even thought to consider bluetooth.
Bluetooth has been bumpier on this phone as well.
If I leave WIFI off, bluetooth runs perfect.
I need more data though to sort this out.
I always leave Bluetooth off when at home, its only on when my phone is in the car dock. But I still couldn't even get through a speed test without wifi disconnecting completely and the test failing.
Ironically, I do not have a single drop out when at work, only at home.
I set Bluetooth Coexistence in my router's settings to Preemptive and so far (5 minutes) so good (I do have other bluetooth devices in the house).
Will report back after further testing.
Oddly, no other devices in my house have ever had this problem, so there is still something funky with the new Evo. But luckily with all these software fixes having varying success with people, it doesn't look like a hardware issue.
Still not a single drop out that I've noticed.
I'll know for sure in the morning. My Titanium Backups to dropbox have failed every.single.night with this phone due to wifi dropping connection in the middle of the upload. We'll see if they complete tonight.
Looking positive.

Awesome. Thanks for the update.
I agree it's odd this Device is stirring up the issues.
But it could be something as dumb as they scan for available bluetooth channels in a different order and tend to hit channels that conflict with WIFI.
Most WIFI I think is on channel 11. I have mine on channel 11 as it seems teh best compromise for the many WIFI devices I have so I didn't want to change it.
So folks migh thave more flexibilty, and just changing WIFI channel can make quite a change.
I'll have to check work, what channel it's on. I'm pretty sure it's not on channel 11 because we have multiple access points and we wanted teh channel non overlapping. So we have them set at both end of teh range if I recall.
That could be a hint as well.

I think you're onto something... If I leave the house and wifi sticks on, then I normally have to reboot phone before I can connect to wifi again. Simply toggling wifi off and on doesn't work.
So on a whim, I turned off bluetooth. Then turned wifi off and back on, and bam! Connected! Hmmmm....
Now with reference to co-existence, that can't be the "fix" because not everyone has access to their router settings (such as at work, hotels, malls, etc.)
WiFi works perfect Bluetooth on the otherhand, haven't tested. But I'm sure works just as fine

bluetooth turning on by itself

Last night while using the galaxy 3 hotspot i noticed bluetooth had been turned on
(i assume remotely) and the bluetooth tethering box was also checked (i assume remotely).
I always keep bluetooth off, but it appeared someone nearby was using the bluetooth connection
to the S3 to gain access to the internet via bluetooth tethering to the hotspot.
My question is, how was someone able to remotely activate bluetooth on the phone when I had it off. Also,
how were they able to check the box for bluetooth tethering to the hotspot which i also leave unchecked?
Is there any way to completely remove the bluetooth sharing app from the phone?
It's not possible, someone is using your device, not remotely using it..
Bluetooth hacks are not possible without the owner knowing.
Wifi hacks are more likely but no control can be gained as the permissions do not exist.
Rogue apps are quite likely.
The most obvious thing I can tell you is for anyone to be connected via Bluetooth they would have to be less than 15ft away to get a reliable connection.
It's very possible and the most likely candidate that bluetooth tether was checked prior to activating tethering.

Need a widget that will tell me when my data connection is ready

I have an automotive head unit running Android 8.0.
Plugged into one of the head unit's USB ports is a 4G dongle that creates a Wi-Fi hotspot.
When I turn my car on, the head unit connects almost instantly to the Wi-Fi hotspot but the 4G data connection isn't quite ready for 15 seconds or so.
Is there a widget I can place that will do something similar to pinging a website (such as Google) and turn green when it gets a response?
