In short: Is it possible to cluster, network or push device output from one device to another, share storage devices and network/gps interfaces?
The long version: I have been wanting to build an in-car device that would store media and act as a gps and what not, but haven't found a way that I want to implement it yet. I was thinking if I found a x86 port of android, got most of the voice stuff working, I could have a headless device that I could store music on and use as navigation. I know the phones are capable of that, but if I want to keep say 500 gb of music on me, how does one do that?
My thoughts were if it were possible to either cluster or network an installed android powered unit to an android powered phone, I could always have network access from the unit in the car and share the gps from the phone, or have the phone access the storage from the device (not through dlna, but the music app seeing it as physical storage) and allow me to push the output from the in car device to the phone and let me interact with the system how ever I need to I could accomplish a form of in-car entertainment.
I figured that there could be apps written that would let the in-car device act as a headless unit, with its only interface being audio, it could store navigation directions/maps and what not, so if I didn't have the phone that day, I could still navigate to where I needed to. The phone and the device could constantly be in communication with each other if the car was parked by a wifi hotspot or something, so if I chose to navigate somewhere when I was at home, the car would already have the directions. I could also have it pull any media changes through wifi, and always have an updated media library.
I know the phones are fully capable of doing this, but for most of it, you have to have a window holster for the car to use the gps, and wires running for audio and charging and what not, but if there were a way that the in-car device could be hardwired to the audio system and left alone, the phone could stay in my pocked, be linked via bluetooth and I could have a small button-pad or something that would allow me to initiate google voice search, control the media player and interact with navigation. The whole thing with linking the phone and device together would be so the mobile network could be shared between android devices and the incar device could pull the information it needed. The thought of the display sharing was in case I needed to interact with the incar device.
I know what I am going on about is specific to me, but my thoughts behind it were if it were possible to do at least the network sharing (with out tethering or mobile hot spot blah blah blah) that android phone and tablet owners could do the same thing. They could share their mobile network through their tablet and have a tablet that would be always connected, would share mailboxes with the phone and basically act the way the Blackberry playbook is proposed or how the Palm Foleo was supposed to work. If the devices had a network ability of some level, the tablet could pull text messages, email messages, contacts or any other sync-able item.. That way, this wouldn't just be done for my benefit, but it would take tablet and phone owners to another league. Two devices that share the same information from one source and don't have to sync with the same servers twice. It would take a lot of redundancy out.
I hope you guys can see usefulness in my idea, and can shed some light for me.
Sorry from bringing this back from the dead, but since I never got any responses I'll add a bit more..
Does android have anything that would work like blackberry bridge between two android devices?
Droid Vnc server and androidvnc works fine for screen sharing. What I really like is the hpc aspects to CPU cycle sharing over wifi/nfc. Really interesting possibilities.
What I am looking for is to have the ability to use two separate android devices, but have them communicate via wifi/bluetooth or what ever and act as the same device in the sense that when the device with the data plan gets a text message or phone call, the notification goes through the other device that would be physically docked to audio equipment or what ever...
I have a Droid X, Droid Incredible, Droid Pro and a first gen Droid laying around.. Currently the Droid Pro is my in use phone.. The rest are just laying here. I want to be able to dock one of the others in my car, turn the GPS on, link it to my droid pro and have the other phone use the droid pro's active data connection for guidance/searches etc, and it would be docked to car audio, so it would need to access the pro's sd card, and have access to the pro's phone audio, or the ability to route calls from the pro to the other device via bluetooth or whatever, not by call forwarding.. This way it would be a sort of infotainment/telematics system..
Think of the possibilities this would open up for android tablets etc. If You could reply to text messages from your tablet because the tablet is linked/bridged to the phone in your pocket... That would make these tablet/laptop combos more appealing because it would the perfect convergence between tablet and phone.
Oh, and I guess, the other thing is that I have multiple cars, so one device would go in each car, and then when I got in the car, the one in that car would link with my phone, and everything would be the same, car to car, or device to device...
I guess another way to bump this:
Would it be possible for an app to do ADB to ADB via bluetooth or something, because then an app could be written like pdanet that would allow the network to be shared at least?
I dont remember the name of the app I think the name of it is Dashboard? and it will store/push all texts/emails etc. to every device u have dashboard installed on...Best buy has an app kinda like that too...Like the Idea of the screen sharing is that kinda like remote desktop/control?
I just search how to neywork cluster android came across your post ..... if you use the Google apps like Google play music/maps as well Google hangouts since with Google voice you can easily do what you want with out the need for both devices being together you can upload 50000 songs 9n play music for free and any device with ur hangouts and voice will receive ur calls and email notifications .....just need to make sure have Internet
Both my wife and I have SGH-T959V with stock 2.3.6 firmware. We have numerous bluetooth devices these two phones are paired to.
My questions.... Once paired, a device should always show up on the bluetooth setting page (as PAIRED) even if that device is turned off or not within distance, right? What if unpairing has been done from that device?
The Scan Device button is to scan new unpaired but ready to be paired (30 sec or so) devices, right? And it has nothing to do with the paired device list below it, right?
Last question. If I turn off the bluetooth on my T959V and turn it back on, my panasonic KX-TG7745 link-to-cell desktop phone would not reconnect even it is set to auto-reconnect every 1 min. I have to manually connect it on my T959V. That is annoying but is that normal?
The problem I have is I am always losing paired devices on the paired device list on my T959V. Power cycling or removing battery might or might not get every device back.
Anyone having the same problem?
Bluetooth on the stock GB ROMs was wildly unreliable for me. I never figured out what it was, but my Motorola hands-free unit would sometimes not connect, sometimes disappear, and often not connect the audio.
I find that the Bluetooth support on AOKP (and probably most of the ICS ROMs derived from the TeamAcid line) to be greatly improved. Shoot, even just being able to give my Motorola a name so I can tell it from the same model in my wife's car is worth it!
Hello everyone, just moved from a Nexus 5 and enjoying many of the unique features, one thing that interests me most is the ability to unlock the phone with a trusted Bluetooth device. I already have a fitbit, so was hoping I could use this, however it turns out you can't, I think it is due to the way Bluetooth 4 is designed to minimise battery drain and it therefore not always connected. I was wondering what other people use , other than say speakers and headphones. I know Motorola have a device planned, but hasn't been released yet.

HX550 earpeace is the only thing I have used. The Moto 360 is the coolest option - but an expensive one. I understand the new micro power-bank is like your fitbit and doesn't do the trick.
I actually have the Power Pack Micro that I use as a trusted device. Works perfectly!
Thanks for the replies, I never knew about the power pack micro, think that is what I will go for, hopefully Motorola will release it in the UK soon.
I connected mine to my desktop PC. Tried it for a bit and it was a cool idea, except that when connected to it the sound would go through the headsets plugged in to the PC. If I tried disabling the audio connection through properties on the PC the phone would disconnect. I couldn't find a way to keep it connected without audio so I ended up removing it.
Would be nice if there was a WiFi option, then I could pair it with that. For now I guess I'll just live without.

Have a look at Skiplock in the play store. I have been using that in the meantime, it works much the same as the trusted devices, but also does wifi. I have it set up with my home wifi network so when my phone is in the house I don't need to put the unlock code into the phone, does Bluetooth as well, just need to get myself one of those power pack micro now...
Advanced Keyguard Manager also let's you bypass the lockscreen based on WiFi connection.

Wifi trusted areas is supposed to come as part of Android L I believe.
You cant use it with your fitbit because it doesnt pair, it only uses bluetooth to sync to the app occasionally. It doesnt have anything to do with BT 4.0 afaik.
The only trusted device I use is my car.

Is there a way to quickly/easily lock the phone when using this? I'd like to do the same, but wonder about the security if someone steals both my phone and my keys -- the phone's power button won't lock the device if the trusted bluetooth is nearby.
Is it possible, for example, to use the button on the Power Pack Micro to disconnect or lock the device? Or is there some quick way to re-enable the PIN using the phone itself? It would presumably be easy with a Moto 360 or a BT headset -- just turn the BT device off, and the connection will be broken. But it's not clear that the Power Pack Micro can be turned off or disconnected without going through the Moto Connect app.
Thanks!

You can quickly lock the screen from the notification shade...there is a persistent notification at the top of the shade saying you're unlocked, and and if you tap it, it locks and stays locked until the next time you unlock it from the PIN/Pattern/PW lockscreen. You could also quickly unlocked it by turning off whatever device you are using as a trusted BT device. The Power Pack Micro has a power button you can turn it off with.
I've got so many things I use as Trusted Devices:
Moto 360
Moto Hint
Power Pack Micro
BT stereo headphones (Bluebuds X)
BT speakers at my work desk
BT HR monitor while at the gym
My cars Sync system
Cobra Tag - this one is really cool device, like the Power Pack it tethers your phone and lets you page it the phone if you've misplaced it, but goes one step further - if you get too far from your phone, both the phone and the Cobra Tag sound an alarm. Great for making sure you don't walk away from a restaurant or home or wherever with your keys in your pocket but the phone left behind (or vice versa). the Power Pack doesn't do that tethering alarm.
To your original concern, if someone walks off with both your BT device and your phone, you're screwed, unless you have time to get on Android Device Manager and remotely lock the phone.
Wow, you have a lot of devices, unfortunately the Motorola powerpack micro is not available in the UK yet, hopefully it will arrive soon.
morning geeks
you have a phone, which is not able to :
show the display
use the touchscreen
but the hardware is still able of these features :
usb mtp device, as a usb key
wifi network
cell network
and so on..
so you are here, somebody gave you a smartphone, running android, locked, but you can't neither see display or use touchscreen;
but its starting anyway, you can hear the ringer if you call on it;
how would you do, without usb debugging enabled, to use this electronic technology as a specific usage, like a wifi AP or a usb key?
in an other words, what is the method to restore it and to take the control of it?
you just have a usb mouse can be connected on it. but no display.
[this is mainly destinated to avoid throwing several android hardware to bin, cause it can still poweron.]
I have been experiencing issues connecting to devices over Bluetooth. Sometimes it just works, other times it doesn't work at all, and some times it kinda works but not right.
All of these issues are resolved by restarting the phone, but that isn't a solution because the issue comes back.
3 Devices I have been having issues with
1. S Pen - Sometimes it won't connect to the phone, I get an "S-Pen Missing" message and it will not connect. If I t ry to connect to it manually via nRF Connect (The Nordic Semiconductors Bluetooth App) it tells me that the BLE device has a GATT error. It happens semi-randomly but I can always make it happen by doing #2
2. Car Stereo - This is the weird one, it will connect and play music, but it will not do "calls" if I connect to Discord it won't recognise the car as a Bluetooth device it can route to.
3. Raspberry Pi - This one it appears it will connect to ONCE, and then after a disconnect it will not connect again.
Again, each of these can be fixed by restarting the device, but they happen again after a while. The pen & RPi use BLE, I don't know what the car uses for calls.
Turn off global power management completely in Device Care.
Network reset, reboot and clear system cache from the boot menu.
Ok, I've done a network reset, and cleared the cache partition. I checked Device Care for something like global power management, and I couldn't find anything. Most of the pwm settings are off except the "optomise daily" setting.
I'll let you know later if I have the same issue again.
These, this is a N10+ running on Pie.
To check if you have disabled global power go to Developer options>standby apps, all buckets should show as active otherwise power management is enable.

Are those the only three devices you connect via BT? What other apps do you use that need to use BT (i.e. Galaxy Wear, Apple Music, etc.).
You mentioned "Nordic Semiconductors Bluetooth App." I looked it up. Why do you need a third party generic BLE connecting app? It seems to me that could be the problem. You shouldn't need a third-party app to connect your BLE devices. The S22U's native pairing will work with any BT device that adheres to BT standards.
Try uninstalling the nRF Connect app and see what happens.
The only other Bluetooth devices I have are other in-house hardware, running on SiliconLabs BGM13P chips or NRF52840 chips...
The NRF app isn't a replacement for your bluetooth pairing app, its a debugging app... it can connect to BLE devices and show their GATT profiles, update devices that have Nordic's OTA update code and copy a devices GATT profile to act as a BLE Server.
We use it for testing and debugging.

Ok. I recommend uninstalling nRF Connect anyway. If anything, to rule out the app. How old is your car and the Raspberry Pi? Even though BT 5.2 is backwards compatible, sometimes older BT devices won't work with newer devices. That doesn't account for the S Pen issue though.
I uninstalled nRF connect, and changed all the settings you both recommended. Exactly the same behaviour when I went to leave work. My car stereo would do music but not calls, then when I restarted my phone, it worked. Then when I got home, my S Pen would not connect to my phone, then I restarted my phone and it worked.
Its not a problem of not being compatible, its a problem of something stops working.
Please also note that these devices worked fine together in the past. I am concered that it is either a change made by an update or a Bluetooth chip that is faulty....
OP- Have you debloated at all and if so maybe you've removed something relevant that might be causing these issues?
No, stock image, no OS modification beyond the things that Samsung offers (GoodLock and Stock customisation)
I have our in-house apps for interacting with our equipment (over Bluetooth) installed, but #1 they shouldn't affect anything if they are not open and #2 they don't do this to ANY of our other test equipment.
I would just like to say, that I appreciate the assistance that you are all offering! I have used many forums over the years when looking for support on things and I rarely find a place that is more ready to try and help than XDA forums!

I've seen the issue of the spen disconnecting but only a couple of times and the issue worked itself out within a couple of minutes with me not having to do anything.
I've also have had a couple of wonky issues when connecting a new Samsung phone to my car. I've narrowed down my issue to the fact that when I transfer my data & settings via Samsung smart switch, it includes the details of my Bluetooth pairings. To fix it, I have to go in and delete my Bluetooth phone settings from the car and from my phone and re-pair them.

As cool as I think Smart-Switch is as a program, I actually never use it when moving from one phone to another. The junk that Google drags with me from one phone to the next is already too much, I like to use a new device as a chance to do some housecleaning. So no old-data oddities here.

Hmmm.. Ok. You're probably right about the suspect causes. I know there is a code you can dial to get into diagnostic mode, I just don't know what it is.
The only other option you can try (as a last resort) is to factory reset it. If it is update caused, a factory reset MAY fix it. If you take it to a service center, send it in for repairs, or do a warranty replacement, they're going to factory reset it, or have you reset it.
have you tried running diagnostics in device care ?
or check with this dc
android
Bluetooth test*#*#232331#*#*
samsung
Bluetooth Test Mode*#232331#
I still haven't done a factory reset, but I continue to have the issue.
I have run the BT Test in device care, it always reports good.
I tried the codes, neither of them work as the first one is for vanilla android and the second is for older versions of Samsung firmware.
I've tried completely unpairing from the car radio and re-pairing, disconnecting and connecting from the other device to no avail.

I'm not entirely sold on the idea that it is a hardware fault. It could be a hardware limitation; meaning you cannot connect to more than a certain number of devices simultaneously. I don't know how many BT devices you can connect to at once. I know at least two simultaneous connections (I've only had two simultaneous connections at a time).
You said you have other BT devices in your house other than those three your having issues with. How many are there? How many are you connected to at any given moment?
Is it possible that you have too many simultaneous connections?
When you try to connect to your car.. Did you check under BT connection (your vehicle) to make sure both audio and calls are checked..

Unless having multiple connections causes the BT to fail completely, no. Even after turning the car off and walking away, it still will not connect to the S Pen. The only BT devices I use with that phone regularly are:
S Pen, Car (Music & Calls)
At work I develop devices that use Bluetooth and I sometimes connect to them, but only ever one at a time.
