[Q] Lollipop phone as trusted bluetooth - Nexus 9 Q&A, Help & Troubleshooting

As I have my phone on me at all times thought I might be able to use it as a trusted device for the tablet? Supposedly lollipop supports android use as Bluetooth LE peripheral but I can't seem to get them to connect in a normal fashion?

I have this working with my LGG2 (running CM11). In order for it to work though, you have to pair the phone to the tablet, then share the phones internet connection. It doesn't seem to be a good solution, as the devices only connect when manually selecting "internet sharing" in the BT phone settings on the tablet.

I'm also trying to accomplish this. Anyone else have a solution for how to use you phone as a trusted device to unlock your lollipop tablet?
As long as I manually established an active Bluetooth connection (by using an app like Tablet Remote) it will stay unlocked, but how can we get a paired trusted phone to establish a connection to a tablet without some sort of manual intervention?
Thanks.

Can't tether via Bluetooth...any ideas?

Hey all. So i've had my A70 for about a week now, and for the life of me I can't figure out how to get this tethered to my phone. I have a Moto Cliq rooted with j_rodd's custom firmware that supports netfilter. I have Wireless Tether app installed and it works fine (I have connected it to my PC and tethered over WiFi).
But for some reason my A70 pairs with the Cliq, but no connection is established. It doesn't see it in the list of paired and tethering capable devices, and there is no way to make the A70 see my Cliq.
I wonder if ther is some way to manually enter the APN info. So far, it only allows me to enter that info if I select USB tethering, but not Bluetooth.
Does anyone have any suggestions? I bought this device because I knew I would be able to tether it. Without that functionality, it really isn't worthwhile for me to keep.
Thx in advance.

[Q] Bluetooth Reverse Tethering to Windows 7 PC?

How can I reverse tether my Android phones to my PC via Bluetooth? Is this even possible?
PC is running Windows 7 x64. Phone is an HTC HD2 running JellyBean AOSP from NAND. I know Wifi would be easiest, but this is a work PC and company policy is we are not allowed to run our own Wifi networks.
I managed to connect the HD2 to the PC via Bluetooth with a PAN network, it only worked when I turned on Internet Tethering on the phone. However, this makes the HD2 into the server and PC into the client so PC can use phone's internet connection. I need the reverse! I need HD2 to be the client, PC to be the server. I found a Bluetooth PAN client from the Play store, but it can't connect via PAN to the PC. I assume because the MS BT stack only has a PAN client and not server. Is there such a thing as a PAN server for PC? I've looked at Widcomm and Bluesoleil BT stacks, but neither specifically mentions having a PAN server.
I found this tutorial that sounds promising, using DUN instead of PAN:
http://bluedunapp.blogspot.com/2012/05/bluetooth-tethering-for-android-devices.html
It's for reverse tethering an Android device to another Android device. Looks like BlueVPN on the Android side will do what I want, be a DUN client. However, similar problem to PAN, I can't find a DUN server. It's apparently not built into the MS BT stack either.
Is it even possible to reverse tether an Android phone to PC over Bluetooth?
Only other idea I can think of is to use an intermediate device as a bridge. USB reverse tether a phone to PC, and use phone's bluetooth tethering abilities to tether my bluetooth phone to it. Really round-about way to go about it though.
not exactl but it works
hi i cant find out a way to connect through bluetooth but i found some apps which can connect your mobile to internet through usb connection
but it requires root access
1.ReverseTether.Trial in google play
2.just search for "reverse tethering galaxy y in google" and select first link from "galaxyyarchive,info" worked for me but dont know about other phones
sorry i cant post links right now
bye

So far there isn't any app that does a reverse tether through Bluetooth. Only Wi-Fi @ usb tether are currently possible.

Unfortunately, I couldn't get this to work. I tried using "Bluetooth PAN for Root Users" on the client phone and it wasn't able to see the Bluetooth connection on the phone which has a Bluetooth tethering checkbox. However, my PC with bluetooth dongle was able to make a PAN connection to that phone, so I guess it's something with the "Bluetooth PAN for Root Users" which isn't compatible.
There's a way to do that using USB Tunneling. An xda member has done this, and I'm using my PC's Internet connection on my HTC Desire with a USB cable. The download below will possibly work for any phone... I'm not taking any credits for this tool and app. This belongs to someone, and I downloaded it, but can't remember who made this. Anyone who knows, please correct me...
I've actually been using that tool for awhile. Its official post is here. http://forum.xda-developers.com/showthread.php?t=1371345

Does the android phone BT stack even support the PAN client role? I guess it may not be there. Could you clarify??
I don't know, I'm going to guess not.
I used to setup Windows on a Broadcom/Widcom bluetooth stack/driver to do this Bluetooth Reverse Tethering for Android - no rooting or apps required. Phone needs to support Bluetooth network access feature - no rooting or apps required as this is a standard/implemented protocol - Samsung S3, Sony Xperia V, Nexus 5, Nexus 4 support it, etc. To check, a phone that supports "bluetooth tethering" would likely support the "bluetooth internet access" (which is "bluetooth reverse tethering") feature. So, as an easy check - on your Android, go to Settings > More… > Tethering & portable hotspot - Now look for a “Bluetooth Tethering” item - if it is available, there’s a good chance that your device is compatible - but if you can’t find it, your device is likely NOT compatible.
As a roughly remember - the steps are like:
1. You need to enable the "Network Access Point" profile in the configuration and you'll get a new "network device"
2. Then in the control panel, go to the connection list, then ctrl-click the new bt-network-device and your LAN ethernet network device - right click and choose "bridge" to bridge it with your LAN.
3. Try pair android phone (which has the bluetooth "internet access" feature) with pc then if all is well, you'll see the bluetooth settings button for your computer - "If this inner settings page has the “Internet Access” item and checkbox shown".
If you tried on the Broadcom stack and still need help - I might try make a blog post with detailed screenshots someday if i can get some free time...
Okay, now I have a new PC running Windows 8.1 which has built-in Broadcom bluetooth, and a different phone, Motorola Droid Mini XT1030. I've installed the most recent WIDCOMM stack.
I'm able to connect a new Bluetooth PAN network device, but there is no "bridge" option. There are for other devices like the PC's built-in Wifi, but not for the bluetooth.
Am I missing something?
I've also tried using USB Reverse Tethering using an old phone as a bridge, but that doesn't work either.

Hi ykasidit,
could you please provide more detail explanation on how to enable the "Network Access Point" profile in the configuration to get this new "network device"?

My 4.2.1 System is missing Bluetooth PAN / DUN Support

Hey Guys,
first post here, so hopefully i don't do anything wrong
Got myself a Freelander PX1 Tablet with Android 4.2.1. Unfortunately I am stuck while trying to use my phone's internet connection via bluetooth. From what it looks like my android system is missing the Private Area Network PAN client support. (no /system/bin/pand)
Is there any way to 'install' this? As the tablet also does not recognize ad-hoc wifi spots I am unable to go online
Thanks!
Cheers
-Daniel
anyone?
I'm wondering the same thing. I just managed to pair an older Lenovo A1 Gingerbread 2.3.4 with a Galaxy S4 JellyBean/CyanogenMod 10.2 by having them pair, then the phone turn on Bluetooth tether (which Gingerbread doesn't support), and connect to the PAN from the tablet using pand.
This works but it's a complete pain that JellyBean doesn't have pand anymore!? Meaning I can't hope to repeat this with 2 JellyBean devices, only older and newer, or some set of in-the-middle Android versions...

sorry to hear that at least that means its not my fault^^
Ok! I happen to have this this post open in my browser so I thought I would share in my success, however obvious it is.
I managed to get a hold of a 2nd JB device. I tested this with 2 Samsung S4s. On the "master" device go into settings -> Network More... -> Tethering- > Enable Bluetooth sharing. Don't do this on the other device. Then pair the devices like normal. The end device should automatically tether through the 1st "master" device. You'll see a BT icon with brackets around it in the system tray. The BT icon will be lit blue on both devices.
If you get into the adb shell and have iwconfig around, on both devices you'll see a new network called "bt-pan". The "master" device will be a .1 (e.g. 192.168.40.1) while the "slave" will be given a DHCP address from the "master". (e.g. 192.168.40.124)
The "pand" tool set is not longer needed. You can just pair normally with newer devices. If you're pairing an older Android device that has bluetooth but not the bluetooth tether option in setting, like my Lenovo A1 GingerBread (which I keep for testing), you'll need to manually using pand to setup the PAN. There are apps that will do this for you.
Hope this helps.

[Q] What is the use of Wifi if i have to connect everything using Bluetooth?

Well, i am bit frustrated because, i have connected to wifi, and i need to connect to the phone, to download, News, Weather data, apps and all these? Then what is the point of Wifi? How is it a standalone device. I also do not have a Samsung device now.
It's not a standalone device and never claimed to be. Yes, it can make calls and has GPS but it does need to be paired with a Samsung phone to fully function. This has been discussed at length and in detail from the launch of the phone.

Any fix for the issue where devices with temp wifi networks for setup don't work

Anyone know what the problem is where Android 6.x and now 7.x where apps do not work for connecting over temporary (non-internet connected) wifi networks to set up a device? For example I can't set up a Google Home or a Vizio smart TV, a Ring Wi-Fi doorbell or connect to a Wi-Fi action camera on my 7.1.2 device, basically anything where a device sets up a temporary network does not work, but if I dig out an old tablet running kitkat or something it work work fine to complete the setup. Since Android 6.x in my experience it will connect to the device's Wi-Fi but fails anyway as if no data is being transferred or something. It seems to be a common problem and it is something I've been dealing with for a good 18 months. Anyone know what the issue is and maybe a workaround for it?
