NclBCBTSrv hangs, prevents bluetooth connection?

I have had problem for years that my bluetooth connection with Nokia PC suite stops working after a couple of days. So far the only solution has been to reboot the computer.
Recently I discovered that NclBCBTSrv.exe was using over 250MB of memory so I killed it. After that it was automatically restarted and PC suite started syncing again.
Is this a known bug? Has anyone else seen this?
I have WIn XP SP3 with all hotfixes from MS, Nokia PC Suite 7.1.40.1
Bluetooth from BroadCom v 2.1.92.108

Sure. NclBCBTSrv.exe is a background process for detecting bt connection. There're also two others: one for cable connection and another for IRDA connection.
You can try to upgrade the blooth driver or re-install pc suite to fix.
What's the law of the jungle?

Bluetooth connection not working on US Nokia phones from J2ME Midlet (MIDP

Hi All,
We are developing a J2ME midlet (MIDP 2.0 ,CLDC 1.1)which makes bluetooth connection to other devices.The bluetooth
connection is working perfectly on indian nokia phones with Airtel as carrier.But when we deploy the same midlet on Nokia E71
US phone with carrier as AT&T ,the bluetooth connection is not working.The sample code is as follows:
public void run(){
try{
StreamConnection connection = (StreamConnection)Connector.open(btConnectionURL);
// open an input stream to get some data
InputStream in = connection.openInputStream();
byte[] serialData;
readData = true;
while(readData == true){
int lengthavai=0;
lengthavai = in.available();
if(lengthavai > 0){
serialData = new byte[lengthavai];
int length = in.read(serialData);
System.out.println("data read: " + new String(serialData));
dataViewForm.append(new String(serialData));
in.close();
connection.close();
}catch(IOException ioe){
ioe.printStackTrace();
when we try to connect on US Phones],the execution hangs at the following line of code:
StreamConnection connection = (StreamConnection)Connector.open(btConnectionURL);
No exception is caught.
Our midlet is not signed.
In the Forums it is said that the problem is with the unsigned midlet.AS some of the US carriers block the secure API usage
on Unsigned midlet.
But our question is, if we buy a code signing certificate from Verisign or Thawte and sign the midlet, will this problem be solved.
Any other alternative solutions for this ???
Immediate help will be appreciated.
Thanks,
Yash

You might want to read this before buying a certificate:
http://javablog.co.uk/2007/08/09/how-midlet-signing-is-killing-j2me/
It's not my blog, but I pretty much agree with what it says. Unfortunately the network operators can control the access 3rd party trusted certificates have, so even if you sign with Verisign for example, the signed midlet may not have any more privileges than an unsigned midlet, depending on network. They do this so that only midlets signed with one of their own certificates have unrestricted privileges forcing anyone who wants a useful application to buy it from the network instead of downloading an equivalent freeware version from Getjar for example. Some networks are worse than others, so signing your midlet will allow it to work on more phones than an unsigned midlet. I think Verisign have some info on AT&T on their website.
The whole MIDP specification for security is a joke, IMHO. I don't mind unsigned midlets flashing up a warning once during an application. Writing 20 files, for example, will give 40 security warnings for reading writing data which is ridiculous, as the user obviously either trusts the app or he doesn't. No one runs an app that they only sometimes trust.
As far as I know the only mobile manufacturer so far to see sense is Sony Ericsson. All of their new phones from Java platform 7 onwards allow unsigned applications access to the file system, bluetooth etc with just one warning when the applications starts.

Google Play Music not playing on Bluetooth connect

I have a SONY E2033 EG4 DUAL, I used to have a Samsung S5. On my Samsung and all other Android phones I have had, my music playlist would auto-start once connected to the car bluetooth. From a google search (ie, "android autoplay music bluetooth") all listings are how to prevent Auto-Play, so I assume this is the default behaviour. With my SONY phone, I literally have to pull the phone out of my pocket, start Google Play and hit Play. The car controls do not work by default. The bluetooth connection is working OK, but for some reason the controls are not being forwarded to Google Play Music until I start the app manually. Is there another SONY app which is taking the requests by default ? How can I override this behaviour ?

Check the SmartConnect settings

I can't get a reliable bluetooth connection betwee...

Hi everyone, I'm new here and already need help. I've recently bought a Nokia 206 and fitted it with a 16Gb micro SD, hoping to copy over some MP3 music files from my PC. I bought a Trust Bluetooth 3.0 USB dongle and installed it on my PC (running Windows 7 Professional). I'm new to Bluetooth so on a learning curve but I managed to get the phone recognised and installed as a device on the PC, paired it and successfully transferred one file but then it appeared to disconnect - at least it wouldn't transfer any more.
I tried various things including removing it from the Windows device list then I couldn't get it to re-recognise as a device. I eventually got around this by uninstalling and reinstalling the Trust software but again I only managed to transfer one file then it seemed to disconnect again.
In desperation I tried installing the Trust on my laptop running Vista Home Edition. Same problem again except this time it transferred two files before hanging.
I was also unable to transfer a test still photo that I took with the phone onto either computer.
On both computers the transfer rate was abysmally slow.
I was really hoping to be able to use the phone as an MP3 player as I previously had an ExpressMusic and that was great. It's a pity the 206 doesn't have a USB port because it's looking as if I'm not going to be able to use the Bluetooth connection.
Solved!
Go to Solution.

Hi Abi99,
The various paths you quoted seem to be a bit different on my 206.
I couldn't find anything in Menu >> Apps >> Gallery >> Images. This was <Empty>, but I found the SD card, named as NO NAME, and in there I found my test photo, stored under 'Images', and my two music files in 'Received files' so these did, in fact, all get stored in the card and not in the phone memory as I had previously thought. This obviously means the Bluetooth file transfer didn't fail due to insufficient memory as there is still 14.3GB free in the memory card.
To get to Camera I had to go via Menu >> Photos >> Camera. Under 'Settings' there isn't a 'Phone storage' but there is 'Photo storage' and that is set to 'Memory card', which confirms my finding above.
Whilst navigating the above I finally found out how to rename the SD card to something sensible.
I wish there was a manual available that would give the above information in more detail. The little booklet supplied with the phone is quite useless for any advanced functions and I can't find anything on the Nokia website.
I think I must have been using a form of Bluetooth File Explorer in the Trust software, as it allowed me to multiple-select the source files for transfer and I now know that it stored them in the SD card, but I can't confirm this or give you the information you requested regarding the software stack unless I re-install the Trust software. Since I haven't been able to make this work reliably on two different PCs and versions of Windows I'm naturally reluctant to try it again.
plepleple - Surely the SD card must be basically ok since I've found the transferred files on it.

Nokia OVI keeps bluetooth connection active

Hi. I recently switched from PC suite to the new OVI suite. This new application keeps the bluetooth connection to the phone active from the moment that you connect to the phone. With PC suite there was only a connection active during communciation. The result is that OVI is communicating with my phone continuously, thus consuming a lot of battery power constantly. I have switched off all automatic sync options. Does anyone know how to stop this continuous bluetooth connection? Thanks in advance. With kind regards, Ron. Nokia Ovi Suite 2.0.2.42 PC Connectivity Solution 9.45.0.0 Connectivity Cable Driver 7.1.23.0 Nokia Ovi Suite Software Updater 2009.40.0.60128 Maps Service API 3.0.38.0 Nokia mPlatform 2.6.40 Ovi Desktop Sync Engine 1.1.0.77 Operating system: Microsoft Windows XP 32-bit Edition, Service Pack 3 Language: English Detected internet browsers: - Microsoft Internet Explorer 7.0.5730.13 Detected Bluetooth stacks: - Microsoft (Version: 5.1.2600, Build: 5512) - IVT BlueSoleil (Version: 2.7.0, Build: 8)

Being a lazy user of Nokia PC Suite (let others go to the Bleeding Edge, don't try and do difficult functions, use it only for basic phone security, ...), I was happily bumbling along, backing up my Contacts, Calendar etc., without a care in the world. Then along comes a 'new and better' version of PC Suite and without much thought I install it and trash the previous version install files. And guess what? The ***bleep*** new version fails to do backup of the Contacts file (just hangs forever). Any bug-fixing or other quick correction for PC Suite now looks unlikely, especially given comments here about Ovi becoming the only Nokia-supported option (even if actually support is patchy or non-existent).
So, looking for pain-free (or at least pain-reduced) alternatives, I investigate Ovi. And one of the first comments I see says that it's a reduced-function form of PC Suite! And PC Suite doesn't work properly anyway!!
And oh look! Ovi may not actually support my phone (6600 Slide) and according to this thread is misuses Bluetooth to the point of draining the phone battery even if no useful activity is in progress. Give me strength!!! Why release ANOTHER pile of , when judging by the LONG list of problems here, there has been no success making its predecessor work properly?

Lenovo A1-07 Ideapad Tablet Bluetooth connection

Nokia C5-03/Win7 Bluetooth connectivity problem

When I am trying to connect Nokia Ovi Suite to my phone using Bluetooth, the pairing process seems to succeed, except the last phase: Then I receive a message that the connection did not succeed. The wizard gives then a possibility to try again with a different ID but it fails every time.
It is the same problem if I try to pair the phone from computer's Bluetooth icon in the notification area. However, with using my laptop with XP this succeeds. Therefore I believe that my phone is OK but there is something wrong with my Bluetooth software in Win 7 computer. Nokia Ovi Suite lists it:
- Microsoft (Version: 6.1.7600, subversion: 16385)
When I start the computer, the Event Viewer shows the following error:
"The Bluetooth driver expected an HCI event with a certain size but did not receive it."
Source: BTHUSB
EventID: 5
The Microsoft's "Event Log Online Help" onthat window does not suggest anything.
However, this may be the actual reason for the problems but I do not know how to fix it.
I have tried Microsoft's "Fix it" tool but it did not fix this problem.
Any ideas what to do?

Still the same problem.
Now I installed the Nokia PC Suite and I tried to make a bluetooth connection to it.
Everything goes again well except after the last phase when I give the asked pin number in my phone, the computer ponders a while and shows then a window with the text that the phone cannot be verified.

How do I connect my Centro to the Internet via bluetooth over PC's Internet? Where is Centro's PPP Connection Type? How do I setup Login Script for bluetooth connection?

I am trying to set up bluetooth on the Centro to connect to the internet via my PC's internet.
HotSync over bluetooth works successfully.
Computer specs: Toshiba P205-S6277; Bluetooth Stack v5.10.04 (currently using); Bluetooth Monitor v3.01 (to use Vista's built-in bluetooth)
I think I have narrowed my problem down to 3 things.
(1) Finding Network Access properties (to allow connected devices to access the internet)
(2) Finding Centro's Network Connection Type: PPP
(3) Finding the correct Login Script to use
for (1) I think I've looked everywhere; found nothing on Network Access.
Checked control panel: only Bluetooth Local COM
Right-clicked bluetooth icon > Settings: File transfer, PAN Networking, PAN DHCP server, AV controls. Other bluetooth settings are for file transfer or object push. I don't see anything like this.
I'm stumped on (2). It seems as if palm removed this option under Centro's Advanced network settings .
Nearly all the forums that I read says to choose Connection Type: PPP.
(3) Found 2 scripts that seemed would work. I don't know how it exactly works but it sounds workable.
First script:
Send: CLIENT
Send: CLIENT
Wait for: CLIENTSERVER
End:
Script 1 Connect Log:
=======================================
Connect Log
S: client
S: client
R:
Err: 0x121F <<<netErrUserCancel b/c I canceled it.
Not connected
========================================
I canceled it because the process would stay on "Signing In" then it automatically "Canceled" itself.
Second script:
Send CR:
Delay: 1
Send: CLIENT
Wait For: CLIENTSERVER
End
**UPDATE** I found on this forum (Reply # 3689) that the script is needed only if you are using Palm OS 4 or under. Centro uses Palm OS 5.49121. Can anyone support this?
Even without the script it has problems "Signing In".
I'm currently reading this site and trying out its decribed methods. I will update this thread when I get the results.
I'm using the Centro. And If anyone's been able to successfully connect to the internet on the Centro via a bluetooth connection to the PC WITHOUT 3rd party applications, please share. If not, please share any ideas.
Thanks!
-Eric

I've been going at this for days, and have probably exhausted all the proposed solutions on the first 3 pages of various google searches. I'm getting the feeling that Vista users are pretty much SOL for the time being.
For the record, I just tried out a few of the solutions (mRouter & SoftickPPP) on XP and they work perfectly.

Bluetooth connection fails iOS 8.1

My iPhone5s cannot make a Bluetooth connectivity with any of my Macs(MBA mid-2013, iMac late-2012, MacPro) all running Yosemite 10.10. Prior to upgrading to Yosemite the same iPhone running on iOS 7 did make successful bluetooth connectivity. My iPhone5s is on 8.1. Surprising even though it cannot have connectivity, it sees and stay connected for a second or two and then will say "Not Connected". But the same phone connects with Blueant S4 handsfree Speakerphone - except that I have to make a connection each time. In the past, it used to connect automatically when I was in the range of my device.
Yes, I have tried reset PRAM, SMC resets on my Macs, powered OFF and ON my iPhone5s and even reset my NW connection. In addition, I have other iPhones in my family and none can make connection to Macs which run on Yosemite(tried 4s, 5 and even 6). But the same iPhones make successful BT on Macs running Mavericks and Mountain Lion(yes one MBP still exists). So I am guessing it is changes in Yosemite that is causing the problem. Because I am going through this problem - my family members who have Macs do not want to upgrade to Yosemite as they depend on BT connectivity for their external devices. I don't blame them, but sounds very silly to me that Apple messed up big time with BT connectivity. I see many reporting similar issues, but for many resetting PRAM and/or SMC they have been successful.
Any help would be appreciated. Again I am not referring to Handoff (which it is working for me) but I am interested in BT connectivity with Yosemite. This is important because external BT devices need to be connected(Headphones, Earbuds etc).

I went to the Apple store yesterday because I was having the same issue in my Honda Accord after I updated to iOS 8.1.1. The very helpful rep there suggested that I go to Settings -> General -> Reset on my phone to reset my iPhone 5 General Settings. She said that it's like an oil change for the phone that cleans out a lot of the junk. After doing this, I was able to stream both my music and Pandora in my car again.
Note: When you reset the General Settings, you will lose your phone password and background image (not a big deal). You will NOT lose your pictures, video or emails.
Hope that helps!

After working fine for several months, my iPhone 5 has started dropping bluetooth connectivity for 2 to 5 seconds at a time with my Sony MDR-1RBT headphones. The headphones work fine with other devices. I haven't moved to ios7 yet. Any ideas?

What user troubleshooting have you done on the phone? The steps are restart, reset, restore from backup, restore as new. Understand that a restore will put the latest iOS on your device. It is also possible there is a hardware fault on the device and the Bluetooth is failing. Anything is possible given the scenario you describe.
And as far as iOS 7.x is concerned, we have 5 different iPhones here at home, all with the latest iOS, a 4, 4s, 5c, and 2-5s and all are working just fine. So, a blanket statement such as the one provided by the other poster is not completely true. Others are not having any issues at all either.

New iMac and Bluetooth connection to mobile phone

PC Suite Upgrade has disabled my bluetooth connect...

Hello!
After using an older version of Nokia PC Suite that came with my model 6233 phone, I decided to upgrade to 6.82.22.0. The older version worked via Bluetooth without any trouble. With the new version, I can no longer make a Bluetooth connection to my phone.
Using the PC (running Windows XP Prof.) Bluetooth connectivity software, I can see and interact with my phone. (I am using an Acer USB Bluetooth device).
When I completly delete all pairings and pair via the Nokia PC Suite software, I can get to the point at which a pairing code must be entered. Upon entering the code and accepting via the phone. . .nothing happens. The button labeled 'next' remains gray and after waiting 20 minutes I am forced to 'cancel'. When I go back to try the process again, the phone is no longer visible. (Via the PC software, yes, but via the Nokia software, no.)
Can anyone help me solve this problem?
Thank you in advance for any suggestions!

I used "Add/Remove Programmes" in Control Panel. It might also be the "Cable Connectivity solution" that Software updater installs. so I uninstalled that - but that broke my cable connection, so I could be wrong.... Either way, I'm now able to connect via Bluetooth which is the main thing.

E51 Drops Bluetooth connection with Car Radio afte...

Hi Guys,
Just wondering if anybody has seen this before. It seems like a few people are seeing this but I have yet to find a solution. My phone pairs perfectly and works as it should for about the first 30 mins, then for no reason, it drops the bluetooth connection and I either have to power my phone or radio on/off. This is very annoying as it has now dropped the call too and I am force to redial.
Sometimes it does not even last 30 mins, and might happen after only 10 mins or so.
Any ideas would be great.
Thanks.

Yes, I have a similar problem which is a real pain if the call is dropped mid-conversation. Have you installed the MS Exchange email client from Nokia because that may cause a disconnect during a poll update.
Other than that I can't suggest anything, except it would be good to get a solution to the problem!
