[Q] Bluetooth stack vs samsung - Nexus 5 Q&A, Help & Troubleshooting

Afternoon all.
I love my N5 and am keen to stick with it - however I have an issue with Bluetooth.
I am a keen runner and user a Garmin Forerunner 220 GPS. This has the ability to pair with a Garmin app using BTLE to transfer run data. However, Garmin are saying that there are underlying issues with the N5 implementation of BTLE that makes this unreliable - resulting in a need to re-pair the devices in the app everytime I turn BT off, or reboot the phone. Due to where I work, I have to do this every day and its a pain!
More details here: https://forums.garmin.com/showthread.php?75976-Compatible-Devices
and some of the reasons for the issues here (I was pointed to this link by Garmin in the thread above): http://au.ibtimes.com/articles/533189/20140107/nexus-5-7-android-4-kitkat.htm#.UxCieF5yFvY
So my question.... is there a ROM available that would give me the same underlying bluetooth stack as the Samsung phones that Garmin declare as compatible (S3/S4, Note2/Note3) ? Would this mean trying to put a pre-KitKat ROM onto the N5 (is this even possible?), or is there a KitKat based ROM that has the same underlying bluetooth stack as the Samsung devices ?
(ps I'm happy flashing ROMs etc. The Samsung devices I have had in the past had a different ROM most weeks! N5 is currently stock but unlocked and rooted).

at& fuse gps problem (not the lag/strength related kind)

ok so i bought an att fuse and like everyone here mentioned about hang ups, weak signal, etc i thought i would just use my old external bluetooth gps unit.
so breifly here is the problem, it works fine when i use a single application like google maps. but when i try to put the information in the external gps app (start>settings>external gps) i have my problem.
under the hardware section, it states:
Specify the hardware port to which your GPS device is connected.
i do so click ok and nothing.. so i go back in to see whats wrong and the gps hardware port resets its self to "none". its as if the settings never save or reset them selves. i know on my old phone (tytn) this would be somthing i considered unusual (so i am kinda familar with the mobile) os.
i am not sure if there is somthing wrong with my handheld or if at&t has some kind of block?
anyway i tried to use the forum search and really didnt turn up any information so any help would be great i really like this phone.
thanks in advance to anyone that can help.
I've never had those settings stick on any of my WinMo phones.
You don't need to use that to use a BT GPS puck anyway, you set the COM port in the Bluetooth settings.
It won't let you make a selection from that drop-down because the GPS hardware does not function by exposing a COM port as with standard hardware, it exposes a GPS0: port, that is picked up by the GPS ID, and exposed to the system as COM4:..
Now because the GPSID has been replaced by HTC's version of it, it's designed to work only with their internal GPS. If you want support for an external GPS in the GPS ID, you need to cook the stock Windows Mobile driver back into the ROM..
That being said, you don't need the GPSID unless you plan to have multiple programs connecting to the GPS at once, so you should be able to squeek by..
thanks guys i knew i would get a respoce here. unfortunatly i was hoping for a easy solution to use external gps with multiple apps i see unfortunatly its not possible without alot of work.
at any rate i am still very hapy with the device i was debating on upgrading from the tytn amd so glad i did =)

Why am I losing paired devices on the paired device list on my T959V?

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!

[Q] Bluetooth blues. (JB and ICS, file transfer, tethering.)

I have a Dell XPS17(laptop), Nokia N900 (phone) and a TF700 (tablet).
I am trying to get Bluetooth anything working on the TF700 with my other devices.
I am running Fedora 17 on the XPS17.
I am running JB on the TF700. Its never been rooted or flashed.
I can browse and file transfer to the N900 from the XPS17. No problems. I can access the N900s 3G data connection from the XPS17, no problem. It works well.
Nothing Bluetooth works with the TF700. It seems to pair to both devices just fine, but that is where it stops.
I want to do the following
- send files to the TF700 from the XPS.
This doesn't work, even though Fedora shows its an available bluetooth service. Fedora attempts the send, but nothing seems to arrive on the TF700.
- browse files on the TF700 from the XPS.
Fedora does not show this is an available service.
- access the N900s 3G data connection from the TF700.
In the settings menu, when I click on the N900 paired device settings, it shows a checkbox for "Use for Internet Access". When I enable that it starts Connecting... and takes forever. Eventually it returns.
When I bring up the pop up small settings menu, it displays the Bluetooth icon in the area where it displays the network connection, but says "No Internet connection". In spite of that, it seems as though I can download a web page or two in Firefox and then the connection dies.
I have no Bluetooth tether "client" software installed on the TF700.
I experienced the same behavior in ICS. I was hoping the JB upgrade would address these issues.
Any ideas on fixing this situation ?
Thanks
i used to be able to send/receive files to/from my galaxy nexus and pc. But since JB, the share option to bluetooth is not available.
bluetooth file transfer from play.
my bluetooth pairing is nightmare.... each time i pair to n900 my tf700t JB4.1.1 gets a reboot.... no problem with ICS... is there a BT driver issue with JB? i saw many other threads with JB BT issues... currently relying on Joikuspot to tether my n900 to tf700t.. gosh this is sick... overall is a good update...

I'm using Mobile Hotspot. Works really well after some tweaking. Amazing to do this on the N900, straight forward, with no hiccups whereas on an iPhone 4 you have to inform the carrier, extra charge and/or jailbreak it.

I installed it. I had it installed previously (ICS) and removed it because it didn't work. Now (JB update) I can send files from the TF700 to my Linux box. Yippee.
But... I want to do TF700 file management from the Linux box (XPS17), not from the TF700 itself.a
I can do this with my N900. On my Linux box, I browse the N900 file system as a mounted device in Dolphin and remotely move, upload/download, delete files on the N900 at will. Its really slick.
It appears as though the Bluetooth File Manager uses (provides ?) OPP and FTP Bluetooth profiles when its running. And yet the available TF700 profiles don't change on my Linux box.
Any ideas on making this work ?
Why isn't JB making various Bluetooth profiles available automatically ? Is there a way to make it, like install an obex server and run it as a service ?
Its ironic that all this stuff "just works" on my 2 year old N900 with the lowly Maemo 5 OS, and it seems so difficult on Android. Caveat, I'm an Android newbie.

Hmmm....
Did you follow the instructions here ?
http://myn900.wordpress.com/2010/08/23/tethering-the-n900-part-3-bluetooth/
What kernel are you running on your N900 ?
What settings are you using on your TF700 ?
More troubleshooting and testing.
I connected my N900 to my Linux box via Bluetooth. In Dolphin it says its using obexftp when browsing the N900 file structure.
I installed Bluetooth File Transfer on my TF700. In BFT, I enabled starting OPP and FTP at boot. I rebooted. I checked in Dolphin and still no browsing option is available in Dolphin. I started BFT. It then told me that it was starting ObexFTP. I check Dolphin and still no browsing option is available in Dolphin. I re paired the TF700 to the Linux box. Still nothing in Dolphin.
Why isn't Dolphin seeing an ObexFTP profile from my TF700 ?
I found one difference between the N900 and the TF700.
$ ps aux | grep obex returns obexd on the N900.
There is no friggin grep on the TF700 !
$ps aux on the TF700 finds it.medevial.blueftp on the TF700. No obexd ! Therein lies the difference.
Has anyone fooled with installing obexd on Android ?
And how do it get grep on this thing ?
Sorry if these are newbie questions.
I did a small search and saw the ability to install obexd (and other libraries) from maemo.org to make BT more functional on devices like the N9000.
Would be nice if we could find something similar like that for Android....

I'm going to put obexd on myself. Stay tuned.
Awesome - when you get it figured out, keep us posted!
I will.
I started digging into it. Seems there is a lot missing on Android compared to a regular Linux machine. Looks like I am going to need Busybox and do a bunch of NDK building. No biggie, just more than I thought it would be.
I'm not too happy with some of the ssh packages that are out there either.
Stay tuned.
Hi!
Did you manage to solve your issues?
I am also owner of n900+tf700 and I am heavily frustrated with this tethering reboots.
I am either using a 3g modem or Mobile Hotspot, but both these workarounds have limitations - modem is another device to have with me and Hotspot app drains battery in a matter of couple of hours.

SW 2 Bluetooth Problem?

Hi,
I've got yesterday sw2. It is really cool, but sometimes i have problem with bluetooth. Sw2 seems to be connected with phone, but when i start some app, it is loading, but this app don't start. I must restart my watch and then everything works fine, but then when i don't use it for a while it didn't want start against. I am using nexus 5 with custom rom. Where can be a problem?
I am having the same problem. Also a nexus 5 with custom rom. Maybe this is a nexus issue?
Which kernel are you running on the phone.
I am using latest Droidkang rom with stock cm kernel.
Some times I will clear phone's RAM to temporarily resolve this problem.
Any ideas anyone? I have the same problem on stock 4.3 on HTC One Max. It drives me nuts ^^
Stock Nexus 5 has no such issue so I'd start with the kernel /ROM bluetooth compatability. Certain apps seem to lose their state occasionally I've noticed. They generally just need to be closed and reopened though. No reboot has been necessary.

Difficulty with MediaTek devices
I have a Wiko Stairway, which is built on MediaTek platform. Pairing is difficult but possible. I don't know whose fault it is, MediaTek or Sony or both?
Still I find it awkard that I have to install 10MB of Sony software just to establish a faulty connection.
My workaround:
Pair the devices without installing the Smart Connect suite
Install Smart Connect and restart watch
Start Smart Connect and wait a while. It should now find the watch and prompt for installing the add-on
Turn bluetooth off and on on both devices
It should now work
Problem is that every now and then the connection is dropped and you may have to toggle bluetooth on either watch or phone or both. Even sometimes a restart is required.
A work around might be to see if force closing the app 'bluetooth share' temporary resolves the issue. If that's the case you could set up a tasker task to kill bluetooth share every 8 hours or so. You might need a plug-in to properly kill bluetooth share with tasker.

Multiple Bluetooth devices at once?

I'm currently on a ROM based on 8.1 that doesn't appear to support multiple Bluetooth devices (Havoc ROM) For instance, I'm looking to connect my Gear S3 and car Bluetooth at the same time and it simply does not let me.
Rather than flashing back to stock to find out and being forced to redownload everything, can someone tell me if the latest release for OP6's stock ROM supports multiple devices being connected at the same time?
I know Android P will cure this, but I am curious if it can be done now.
Thank you guys! Loving this phone so far
no
