[Nexus 7 Q&A, Help & Troubleshooting] khaytsus:
Thanks for the tip, I might try this.. I've been frustrated with doing this in Tasker, for some bizarre reason it makes Tasker act crazy to do stuff "on screen off" beyond a few simple commands. I'm going to eventually post my task to the Tasker forums and see if I can figure out what's going on.

Basically same situation, Wifi and bluetooth off at screen off, both turn back on on screen on. If bluetooth was off, and wifi can't find an AP after 10s it prompts to turn on bluetooth to tether to my phone. Works great in theory, but in reality it goes crazy slow sometimes. :(

I have Bluevpn, Nokia N8 and Galaxy Tab 10.1.

The Nokia and Tab are paired and can send/receive files ok but when I try Bluevpn on my Tab it says modem negotiation after it connects to my phone (the Nokia).

Anyone get it to connect?

If so, can you give me a walk through of the Bluevpn 1.3 settings.

Thanks,

I installed Bluetooth Keepalive which keeps my GNex from disconnecting the Bluetooth when it sleeps. I've noticed that once the BT has been turned off, it turns off the BT tether, you have to reselect Bluetooth tether in the menu each time BT is turned on.

I've got a 9780 as well. I got some connectivity by using "PDANet for Blackberry" (Google to find download) and BlueVPN (by same company, June Fabrics) on my Nexus 7. It creates a bluetooth DUN connection. I can browse, but Google Maps says it has no connection. I can purchase apps from Google Play, but purchases can't be downloaded. Still figuring out what does and doesn't work, but it's better than nothing for now.

I also noticed that "PDANet Tablet" has a Blackberry bluetooth connection option listed as "coming soon" so I'm hoping the next release of that Android app might figure this out.

And oh yeah, I had to disable WiFi on my Blackberry before it started working.

Problem: No internet connection using bluetooth [solved]

You are not able to connect the N7 with your smartphone using bluetooth? :(

But you can pair the N7 with your smartphone?

It could be a well known ics bug. :laugh:

Perhaps your N7 was in flightmode sometimes before and while flightmode it went in standby. Then your N7 isn't able to take internetconnection via bluetooth anymore. So happened to me.

In another forum I found a way to solve the problem: :highfive:

Easily start flightmode and after a few seconds disable flightmode.

Now bluetooth will work fine. :good:

Hope I could help you. [In case you are invited to press the thanks button] :fingers-crossed:

I read in another forum (re: Open Garden, which builds a VPN also) that the reason why Google apps won't download is that that it checks for a WiFi connection, but sees none, so doesn't look further or notice that there is an active VPN in place. This is said to be a Google bug.

I'm able to tether my Nexus 7 to my Nexus S via bluetooth paired, but if my Nexus S goes to sleep (screen turns off) the connection stops. Is there any file or configuration at root level that can be changed to keep the bluetooth connection alive when the screen shuts off?

Look in the market for bluetoothkeepalive. It works wonders.
[Nexus 7 Q&A, Help & Troubleshooting] handfish:
+1

https://play.google.com/store/apps/details?id=org.floodping.BluetoothKeepalive

It works flawlessly.

Coupled with Tasker, bluetooth auto tethering and bluetooth auto connect, my Nexus 7 will now automatically tether with my Galaxy Nexus.

My setup at the moment:

Galaxy Nexus:

- Bluetooth always ON

- Bluetooth keepalive installed (this app automatically runs a wakelock everytime when *any* bluetooth device is connected and drops the wakelock when all devices are disconnected.)

- Bluetooth auto tethering installed (this is needed to automatically enable bluetooth tether at boot time)

Nexus 7:

- Bluetooth is by default OFF

- WIFI is always ON

- Bluetooth auto connect installed and configured (when Bluetooth is turned ON, the tablet will automatically connect to the Galaxy Nexus)

- Tasker installed (has a profile that automatically turn ON bluetooth when WIFI is NOT connected; an exit task is added in order to turn OFF bluetooth when WIFI is connected)

This works PERFECTLY!!! Battery on the Galaxy Nexus suffers a bit due to the wakelock, but this is REQUIRED in order to maintain a stable bluetooth tethering connection. Note that the battery consumption is much much much better than using WIFI tethering!

Never have any Internet drop out with my current setup. Even CISCO AnyConnect VPN works fine with this setup; the VPN will automatically resume upon disconnection and re-connection. Also, no issue with connecting both my car's bluetooth system and the Nexus 7 to the Galaxy Nexus at the same time! :D
[Nexus 7 Q&A, Help & Troubleshooting] kwhy:
so the keyword there is the phone needs a partial walklock to keep the CPU running so bluetooth doesn't disconnect after the screen shuts off and goes into lock mode.

thanks.

I also found the free program

Wake Lock - Power Manager (Free) on the Android Market by Darken works

https://play.google.com/store/apps/details?id=eu.thedarken.wl&hl=en

You can select the type of wake lock mode (partial if you want screen to turn off) and the bluetooth doesn't disconnect when the screen is locked when your tethered to your phone.

Anyone know if is possible to code a *partial wakelock* by writing a name to the file...

sys/power/wake_lock

then to release writing that name to

sys/power/wake_unlock

I know this will cause a wake_lock, but unsure if it keeps the screen on or not.

I'll have to play with the tasker app. thanks for the recommendations.
[Nexus 7 Q&A, Help & Troubleshooting] Milamber33:
I poked around and found this app: https://play.google.com/store/apps/details?id=com.gejos.android.wakemyandroidpro. I've only been using it a couple of days, but it does seem to be doing what it says it does, keeps wireless connections open (INCLUDING Bluetooth, I have tested) without causing much greater battery drain than normal. Try it out, it's a great free alternative to BluetoothKeepalive, and may actually do a better job.

With regard to needing to install an app to keep bluetooth connected...

I do not use a lock screen at all, it is disabled (useless IMHO) and I have not had any problems at all with bluetooth. Its how I get data connection at work. its awesome. So, why is everyone having problems? Is the lockscreen necessary really?

Im running CM10 on both my Ville and Grouper so Im using the native settings and using my phone to give my N7 connection when not in wifi.

N7 Ville

both devices can have their screens off and when I wake up the N7 up, its still connected. Maybe just make a shortcut on homescreen to kill security lockscreen when you need that bluetooth?
[Nexus 7 Q&A, Help & Troubleshooting] brianbgrp:
Its a bug with certain phones. Ie galaxy nexus. Without bt keepalive mine drops soon as the phone isles. With the app works like a pro.

And the wakelock is barely noticable to the phone battery for me. Running aosp plus Trinity on both devices and my phone barely drains more than usual while tethered this way

Nexus 7 with IPhone 4.... works but today not

Wow I didn't expect thet. But here is what I got. I used my Nexus7 paired to my non Jailbroken IPhone 4. It worked with a little workaround. This was like a week ago. I could use BT Tether as I need it just turn on BT and connect.

But somehow this morning it's not working anymore. Connection lost after less then a second. I tried to start from the scratch and used the now known workaround but.... guess what. It's no longer possible.

So this leads me to this Forum and to two questions.

1. WTF is happening there? (No one of both had any update or so)

2. Is there a way to make it work again and better?

For Information here is a shor list how to do the workaround to get both connected:

1. Activate Tethering

2. Activate Bluetooth on both

3. Deactivate Wlan on both

4. Pairing starts from the IPhone

5. Pairing accept on Iphone

6. Pairing accept on Nexus 7 (this is important otherwise there will be "Device not supported" on IPhone)

Got my nexus 7 automatically bluetooth tether to an iphone 5 since friday. Similar setup with my old galaxy nexus. Just pair the nexus 7 with the iphone, enable personal hotspot on the iphone, on the nexus 7, go to bluetooth setting and select the iphone there.

To automate the connection, like I said in the past, I installed bluetooth auto connect, select the iphone as the default device to connect, use tasker to turn on bluetooth automatically when wifi is not connected (otherwise, turn off bluetooth).

On a side note, the battery life on my iphone 5 is poorer than my galaxy nexus. Same setup and same usage with bluetooth tether.

To share the conection of my Xperia S, I only have to turn on bluetooth on both devices, they connect toguether automatically if the nexus isn't connected to any wifi

The Xperia turns on the bluetooth thethetirng automatically too, and it doesn't drain the battery, maybe a 10% in three hours and only if you are using it

Got it working too without bluetooth keepalive app between N7 and Optimus Black running CM7. I do have Tablet Talk that might have help to keep to connection from dropping randomly. But it wouldn't tether if wifi is on which make sense, it even drop the bluetooth tether if I turn the wifi on which is perfect. Love it!

Issues I'm having with BT tether.

Hello folks, looking for advice, on a Nexus 7 rooted, stock ROM, how can I Tether using Bluetooth if I want to use the car stereo system for voice navigation and playing music. I have a rooted VM701 Slider (great little phone by the way) and I can tether all day long on WiFi and get audio from the N7 to my car stereo and Navigate just fine. but if I try to go Bluetooth DUN to tether, I loose audio from the N7 on the car system everything will work fine but the audio. I pair the N7 as audio device on the car system and the phone as phone device for hands free, I'm using Foxfi on the phone and PdaNet for tablet on the N7. I can connect to the car system using Bluetooth and navigate and play music without any problems with the phone even though I have to use the stock audio player or the JVC headunit display will show "pause" and it won't go away until I hit play on the phone audio app. I wish there was a way to make JetAudio the default app for music, so to sum it up I would be a happy camper if I could connect my phone, the N7 tethered, using Bluetooth to the car stereo for Nav and music play, hope all this makes sense. Thanks again.
[Nexus 7 Q&A, Help & Troubleshooting] Herb0515:
Not sure what's going on with Bluetooth and Pandora for you guys , I have a Pioneer nav system, on a pathfinder, had it for over a year, I have always been able to connect via BT to it and play Pandora no problem. The issue I have on the other car, where I use the N7 rooted, stock Rom is that I can WiFi all day w/o any problems, but over Bluetooth Dun I loose the car audio on the N7, still can hear audio from the tablet but not over the car stereo, when I use the phone for audio everything works, either Bluetooth or WiFi. I want to use the N7 as an audio device and the phone for hands free operations but so far no luck with the tablet, as an audio connection via BT, seems like it can't connect to the radio and tether via BT to the phone at the same time, the radio is a JVC dual BT capable, I use the phone profile for the VM701 Slider (Foxfi) either BT or WiFi and for the N7 I use the audio profile (PdaNet for Tablet) any positive comments on how to solve this will be appreciated. Thanks

I have seen it posted in other threads/forums that some apps are not "smart enough" to check for the existence of a bluetooth connection before giving up. They simply check to see if a

Wifi connection

exists and if it finds none, then it looks no further and gives up. In my experience, there are several apps (e.g. Google Play) that simply won't use a bluetooth connection.

I've also read in other threads/forums, that this limitation

can only be fixed at the OS level

. Whether that's true or false, I'm not smart enough to say, but it makes sense to me, so I accept it as true. Perhaps a new/next version of the Jelly Bean (and prior) will fix this. Or maybe there needs to be a fix in both the OS and in apps?

FYI, I'm having great luck with the following two apps, from the same author.. The first one, Auto Tethering, automatically re-enables BT Tether on your ICS/JB phone after a reobot (it normally turns off on reboots). The second one, Auto Connect, automatically connects to a bluetooth device if it's available so you can use a BT Widget toggle or something to turn on BT and it'll automatically connect to your phone.

You could also use Green Power to turn BT on/off on screen off, of what I'm doing is using Tasker, that way it doesn't stay connected all of the time (unless that's what you really want).
[Nexus 7 Q&A, Help & Troubleshooting] PsychoMcSatan:
So what is your configuration, like what 3rd party apps are you using? It seems a few of us can get the tether going with web browsing, but apps cannot see the connection. I'm currently using BlueVPN on the N7, tethered to my Blackberry 9780 running PDAnet. I'm thinking I need something other than that BlueVPN since it seems like the Blackberry is serving fine, but my N7 doesn't see a true internet connection.

edit: Looks like the just-posted suggestion of Bluetooth Auto Connect is worth a try

edit2: Bluetooth Auto Connect looks like it needs and Android phone to tether to. I think BlueVPN is the only solution to tether to a Blackberry and I just looked at its Google Play page and it appears that the author is aware of the limitation and has an Android bug report open (id=33666), but then I'm curious how that Bluetooth Auto Connect works for the previous poster.

I honestly do not see how t mobile could tell the difference between a nexus 7 and my htc amaze without some sort of deep packet inspection, which they might use on real heavy data users... who knows. I have heard that t mobile dues use packet inspection to check user agent strings.. if you check your user agent string, lots of sites to do this on, you will notice that it says nexus 7. This is fairly easy to bypass though(I haven't bothered ). I believe dolphin browser supports user agent changing. Simply check user agent on your phone, copy it, change user agent on nexus to the same as the phone. If you did that, I don't really see any way t mobile could tell the difference between one android device or another.. and fir non-web data, I have no clue how they would being that the same apps are requesting the same data. If it ever became a problem I would simply set up an encrypted tunnel through my vps... Then they would have no idea what is inside the packets.

It's the way that open garden establishes the bluetooth network connection, I am guessing it uses Bluetooth DUN as opposed to PAN. I'd recommend wireless tether for root users if you're rooted and run a kernel with netfilter/iptables support. That app can establish a Bluetooth personal area network which should act like any other mobile data connection. I use the built in functionality in my ROM, option to "share internet connection with this device" under the options fir said device in the bluetooth menu, works great with everything

My phone is a Droid Razr Maxx. It is rooted, but otherwise stock ICS 4.0.4. I tried Wireless Tether for Root Users with bluetooth. My N7 connects to my Razr via bluetooth just fine, but there's no IP, so I guess that my kernel doesn't have netfilter/iptables support.

Any suggestions on how to find a kernel that has this?

Although I've installed custom kernels and ROMs on phones in the past, this (netfilter/iptables) isn't a feature that I've ever seen mentioned before in the description of any kernel.
[Nexus 7 Q&A, Help & Troubleshooting] ericdjobs:
I believe the majority of custom kernels SHOULD support it, as it's just a couple of configuration flags during compile (I THINK, don't quote me on that, I'm not a kernel dev!)

You'd have to either find a custom kernel for your device and ask the dev, or check the source/defconfig file. I don't believe a stock kernel would have iptables support and I'm positive there would be absolutely no support for loadable kernel modules.. as they present a huge security risk.

SOLVED - Reliably Tethering by Bluetooth Now

I think that I've finally found why my Droid Razr Maxx and my Nexus 7 would connect by Bluetooth, but would not share internet

reliably

. It would work for days or weeks, then not work for no apparent reason. I think that there is a bug/limitation in the default built-in Mobile Hotspot app that I use (plus Bluetooth Auto-Tether on my phone and Bluetooth Auto-Connect on my tablet). It seems that after a while, the Mobile Hotspot app

stops giving out IP addresses

. I solved this problem by re-booting my phone. Next time this happens, I'm going to see if merely doing a Force Stop on Mobile Hotspot will do just as well as a reboot.
