I have my evo on jelly bean (ota + root, S-ON, booloader unlocked, TWRP). Previously when it came into range of my car's Bt, my HS3000 samsung receiver, or my Bt receiver on my HTIB, simply turning on bluetooth would connect to whichever devices were around. after jelly bean (or some inadvertent setting change on my part) i now have to go to BT settings, select the device i want it paired to and click it. After this, connection is established and media/phone etc all work fine.
Its a little annoying to have to do connect to the devices manually even though they are already paired...
I have tasker, maybe someone with a little experience automating this kinda process can tell me how to make it look for the three devices when i turn on bluetooth and connect to whichever one is available. I know the phone is capable (it did this on its own before Jb), im not sure if theres something im missing/or if i jacked something up without knowing.
any advice is appreciated, I did search for people who were having similar problems to no avail. If i missed this particular answer, please dont flame me (im an evo lte newb)

So I got my self to thinking; What is the best way to handle connectivity for my devices?
I have a rooted/rom'd Evo Shift, and will have my gTab soon (hopefully). I generally leave BT on my phone on all the time, and it is currently paired with my Car's head unit to stream audio and hands free calls.
Do I pair my table to my phone via BT and tether?
What are the consequences of leaving that on all the time? How would that affect the battery life of the phone and tablet? I know in the old days when you used the PAM (phone as modem) your phone didn't get any internet connectivity. Is that the case with BT tethering?
Do I pair my tablet with my head unit? I don't know if it can be paired with more then one device. I doubt it though. Maybe just pair hands free from my phone and a2dp from the gtab? Not sure if that is possible, have to read the head unit's manual.
I apologize for the incoherent ramblings. I'm trying to figure out what other people have done along with what works well, or what doesn't work at all.
Thanks,
So I've read up a little more and found some answers.
Looks like I can get GPS information from my phone via blue tooth. This will be awesome in the car. Any one who has done this, is it possible to get internet tethering via blue tooth from the same phone at the same time?
Using wifi to tether data while i use blue tooth for GPS information is possible, but doesn't seem very elegant.
It doesn't look like my head unit can have multiple BT pairings active at the same time. Guess I will have to use an aux cable for the tab and BT for my phone.
An ideal solution would be for my tab to use wifi for internet if available, and tether via BT to my phone if a wifi network is not available. It would be nice to leave the tethering open all day, but I think that would drain my phones battery something fierce. My over all concept it to have a personal network of interconnected devices with my phone acting as their connection to the internet.
Any advice, comments, death threats or criticism (constructive or not).
Bluetooth GPS sharing is very doable. There are several threads dedicated to setting this up. Looks like you may have found a few of them.
Tethering BT data to your phone is also very doable. Again, there are several threads on this, and I'm pretty active in most of them. Been working on this for a bit.
Start with this one:

Wifi tethering is much easier. The issue I've had is mostly around BT and Wifi signal conflicts. I don't see it much in just using BT GPS and WiFi Data, but if I receive a call (I use a BT headset when on the road), the quality of my call is in the toilet for at least a minute or so. My guess is that the Tab is trying to get WiFI data from the phone (which it won't be able to because I'm on the phone - VZW CDMA - can't be on the Net and on phone at same time). After about a minute or so, it calms down. Unacceptable solution though.
So, I've now been mostly doing GPS & Data through Bluetooth to the phone. The problem with this hookup is again when I take a call, of course my Data drops on the tab (no way around that). But even worse, the GPS signal gets degraded too. I'm thinking just not enough Bluetooth bandwidth to support Headset, Data, and GPS at the same time?
So my most recent setup (just tried it for a bit today) is to use an external Bluetooth GPS (got one on Amazon for about $25.00) and then Bluetooth Tether to the phone for data. It's a little bit complicated, and involves yet another 'gadget', but I am getting the best results from this setup so far.
Thanks for the info.
I'm on sprint and know the "no data and voice" problem all to well. Even when using maps for navigation on my phone, if a call comes in, the GPS becomes retarded and inaccurate. Once the call ends, all is good.
with getting data from your phone via bluetooth, is that something you leave on all the time or do you have to turn on BT tethering when you want data?

I haven't been using that often to be honest. So when I do, I turn on BT tethering at that time.
I also use Co-Pilot for Navigation. It doesn't need data, just GPS. Map data is downloaded to the sdcard. Just depends on how I feel at that moment. Both nav systems have their advantages/disadvantages.
I'll have to check out co-pilot. storing maps for offline use sounds like a good idea, as long as they don't get stale.
OK, so I've kind of got blue tooth GPS data working. Using an app called "ShareGPS" on my phone and "BlueToothGPS" on my gtab, I've successfully gotten gps data to my tab. Using the BlueToothGPS app on my tab, i can see satellites and GPS data flowing. Unfortunately maps doesn't seem to get location data, and there doesn't appear to be a way to enable GPS data in any of the settings.
Running TnT lite. Any one know how I can get maps to see the GPS data?
I just got my Tab last night and while at work, decided to download a book that I'm in the middle of (Amazon archive). Our wifi at work is weak (to say the least) and I couldn't keep a connection long enough to download one book. It finally dawned on me that my rooted Evo has wireless tether. It worked like a champ! It's the first time I've used it and I gotta tell you, that alone made my day. Nice strong connection and I was able to websurf to my heart's content. I'm running TnT Lite 4.40.
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

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.
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.
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.
Heyyyy,
So I have a Samsung Galaxy V, Unrooted, and Locked Bootloader. I've been trying to use all sorts of remote apps that require to sync itself with my wifi connection (i.e. remote control, universal remote, mobile gamepad) but to no avail. The kinds of troubleshooting advice I usually get or read about generally just tell me that it SHOULD connect itself automatically after I install the server thing on my pc but it never does. This goes with all said apps. I've tried pinging my pc to the ports required to be connected to through my smartphone but nothing seems to be out of place, I even checked a few things that I could understand on my router settings but I've never really figured anything out.
In short, I would like to ask if anybody knows of a way to possibly diagnose the problem that might be causing my smartphone to not sync up with my wifi regardless of having the same connection.
If it matters, my phone is on a wifi, but my pc is wired, however that doesn't seem to be much of a problem according to the many troubleshooting attempts I've read, but yeah, that's basically the stiffy.
Thanks for your time, cheers.
