Bluetooth SPP not shown

Hi,
a while ago I bought a Nokia 3250 phone and in the manual it says that it supports SPP next to a list of other services. When I try to enable it in the Bluetooth options, though, it only displays DUN.
A friend of mine was suggesting that Windows is the problem and I should switch to Linux as I really need to get this going because this project is part of my graduation. If anyone has experience please advise me whether it could help or not
Thanks in advance!

I want to write a little app on the phone that initiates a connection to the previously paired PC and communicate with Hyperterminal through a serial port. In the end I want the phone to send a string to the PC which is then printed in Hyperterminal.
The project was originally to connect to a BT relay, but as they cost quite something I wanted to simulate a BT relay, using the PC instead of the relay. The relays are mostly controlled the same way, by sending a string with a special command to the controller. The message doesn't matter, so I just want it to send "start" and "stop" to the PC, which then proves the success by printing it out. The phone doesn't even need any confirmation, just this one sting needs to be printed.
The problem now is that I can't initiate a connection from the phone and/or stay connected with the computer so that I could figure out a way to connect to the COM port. I was searching for the cause and found that the only service advertised is DUN. I thought this could be one of the problems behind it.
What made me wonder was that in all the websites that describe how the phone installs it says that in the end it should show 2 COM ports which should be noted for further use later on. With me it never showed them.
I also tried connecting with another system, Vista instead of XP. What really surprised me is that it shows about six services all dependent of SPP, but not SPP itself. So I was wondering if perhaps the system just can't handle it. Maybe Linux can help...?
I'm also going to get a new Bluetooth dongle to test whether the one I'm using at the moment is faulty.
So yeah. I'm stuck with not being able to connect to the PC without initiating it first from the PC and not being able to connect to the COM port. 
Thanks a lot for your answer! Hopefully we can work it out

  • Z10 - new contacts saved on smartphone​, but not shown in contact list

    Hello everybody,
    I have a problem with my Z10. It does not show me any new contacts in the contact app on the phone. After entering a new contact through the app (from HUB and directly) it won't be shown in my contact list. Not even the phone no in the HUB has been replaced by the name. Sending a new contact from BB9810 by Bluetooth does not even get the contact into the new contact list (even though it's been saved).
    Anyway, the contacts have been saved somewhere in the phone, since I can sync them with the BB link on my laptop. Also entering a contact in my windows contacts and syncing the other way around (from laptop to BB) does not get me the contacts into my BB contact list.
    Has anybody experienced the same issue, or can advise me where to change settings or do something that may get everything back to normal?
    Thanks a lot in advance

    Do this for me.
    Do a simple reboot on the BlackBerry in this manner: Reboot: On the side edge volume keys, press and hold down both of the Up and Down volume keys for about 20 seconds, ignoring the initial screenshot message... the screen will go black and reboot.
    Now, after the reboot is complete, give it a couple minutes and check your Contacts app again for those missing contacts.

  • Does Palm Pre Support Bluetooth SPP Profile?

    I am a developer for a software company.  I write all the application software mainly for Windows Mobile to control our hardware in the field using Bluetooth SPP Profile, or Serial Port over Bluetooth.  Some clients have asked if they can use their Palm Pre phones to control our hardware.  
    Does Palm Pre support SPP?
    Post relates to: Palm IIIc

    At this itme the PRE does not support the SPP profile.
    These are the profiles currently enabled on the PRE;
    HSP 1.1, HFP 1.5, PBA, A2DP, AVRC, PAN
    version 2.1+EDR

  • Some fonts are not shown correctly in LabVIEW 2012

    I found a bug related with fonts in LabVIEW2012 f3 KR.
    - When I select NI7SEG in font selection dialog, right font is not shown in the example box.
    - Draw text at point.vi shows same problem for some fonts while other fonts are working.
    I reported it to Korean NI. As far as I know, this was not reported in previous versions and I couldn't find any related documents in Google. 
    So, here I would like to know whether it is related with only Korean version. Please let me know if English version is OK. 
    * OS: Windows 7 32bit KR

    Just now, I installed LabVIEW 2012 f3 (32-bit, English) and checked for the issue. But the font(NI7SEG) was not shown properly in VI either.
    - Both of Korea and English version of LabVIEW 2012 on Win 7 Korea OS shows wrong results. It is same on 64-bit OS.
    - LabVIEW 2010 but on same PC shows correct fonts.
    Is there a limit of number of fonts in LabVIEW? There are more than 100 fonts are shown in the "Selection Font" dialog and I can divide them into 3 groups by sequential order. I find that all fonts in the 3rd group are not applied correctly.
    (1st group)
    Arial Unicode MS...
    Bookshelf Symbol 3....
    Windings 3
    (2nd group)
    @Arial Unicode MS...
    @Terminal
    (3rd group)

    Consolas...
    Courier...

  • IPC/VC: Knowledgebase/KB of ECC is not shown in CRM

    Hi,
    we would like to use the Variant Configuration in CRM.
    Today we are using already the IPC in a standalone environment with an external system (IPC 5.0, the external system is using the IPC in the Java environment of ERP). From the same ECC System we would like to download now the knowledge bases to reuse them in CRM 7.0. All knowledge bases and runtime environments are already available. When I download the object SCE (with certain filters), I can see all those entries in table COMM_CFGKB in CRM.
    Anyhow, when checking the material in CRM (e.g. commpr01 or WebUI), no knowledge base is shown!
    The table COMM_CFGKB has exactly the same entries as ECC (Active = T, KB Usage 10, KBOBJNAME and Version filled etc.), but anyhow it is not shown at all in CRM. As these knowledge bases are very huge, I have tested also a very small and easy one. This one is getting downloaded the same way and has the same entries in table COMM_CFGKB and it is also visible in commpr01.
    So my assumption is that the other KBs are not 100% correct. When checking them in ECC (cu36) I get many warnings and errors. Anyhow, they were downloaded to CRM (but won`t be shown). Business says that these warnings/errors are OK and that the external system which uses the IPC in ECC is not having any problems.
    Question: is there any chance of using a KB in CRM which has warning/errors when it was generated in ECC?
    Is there any chance of manipulating the KB before it gets imported into CRM. I have found Note 1044682 which explains a BADI.
    Which tables/fields do we have to manipulate so we are able to use the KB in CRM. 
    As mentioned: business is aware of those errors and excepts that there might be a crash in the IPC for certain combinations.
    Thx
    Guido

    Hi Christophe,
    OK, I think I understand your suggestion: you use the same IPC with your CRM as well as with the ECC system. So in CRM you just maintain the URL and a user in XCM to the "same" IPC. You mentioned that we need to download anyway the SCE. This is somehow logical as this is the base connected to CRM, but what is not clear to me is the fact, that if the SCE KB is used via ECC all SAP R/3 fields are available (like VBTYPE of the sales order where you have values like B or C). In CRM we use the same SCE KB but here these fields are not availble as the sales order transaction customizing in CRM does not contain such a field.  Where is the logical link between the values which are available in IPC and the SCE?
    Thx
    Guido

  • Voice memos sync not shown in iTunes

  • Satellite U400 - error - Bluetooth has not started

    I have used my u400 for 3 months without problem...
    Then suddenly several problems with bluetooth occured...
    When I wanted to use BT for example OBEX, I got error msg: "Bluetooth has not started".
    I tried to reinstall driver for bt, but I couldn't. I got this error msg: "Please insert BT stack". So I decided to reinstall windows vista with recovery disk. On fresh install of vista, there were no bt drivers pre-installed. So I installed drivers and everything was fine for 2 days..
    Now bluetooth is not working again.. can NOT reinstall drivers becouse of error msg again (Please insert BT stack) (Of course, the wifi switch is turned on).. The interesting thing is that in device manager is no BT hardware...
    Any ideas?

    Hi buddy
    Ive got a U400 too and I never had any BT issues
    I updated the BIOS to the latest state
    Did you do this too?
    If not you could try to update the BIOS
    Furthermore I recommend enabling the BT using the FN+F8 key combination
    Using this buttons you can enable and disable the Bluetooth and WLan
    Check it!

  • Yosemite 10.10.1: Finder/CIFS mount problem: wrong folder count/folders not shown @samba shares

    Hello to all,
    we have several MacBook Pro (15" MBP Retina 2012/13"MBP Retina 2014) running. After upgrading to Yosemite 10.10.1 we had one nightmare after the other.
    Most problems could be solved with 3rd party software upgrades but there are several problems with the operating system itselve which can not really  be called a professional productive system at the moment...
    Ok., one thing after the other...here is one of our biggest problems:
    After upgrading from Mavericks or Mountain Lion to Yosemite 10.10.1 the CIFS/SMB mounts to our samba 3.x servers, running on Ubuntu Linux LTS 12.04 makes trouble. We could mount the server shares but after browsing with the Finder the beach ball occures and the Finder hangs forever. Sometimes we could not refresh the Finder, killing the process ended in a complete hang-up of the system which ended in a switch off death blow. This is not amusing because we have 30Tb of customer data there, which has to be worked out.
    We heard about the SMB3 protocol which will be used per default in Yosemite and so we decided after some testings to upgrate our Ubuntu servers to the latest LSF 14.04. release with samba 4.1.6 installed. There was no message from Apple for this SMB protocol release upgrade, never heard something related to Yosemite (Why?).
    Ok, after these server upgrades and disabling most of the Spotlight functions the performance to the CIFS shares was a little bit better as before but now we have another problem with the Finder...if you browse to the shares there are folders missing which have lots of files in it. For example there is a folder with 60 subfolders and 3562 files on the first level in it, the Finder shows 220 files and 15 folders. The Terminal shows a different count with "find . -maxdepth 1 -type d | wc -l" or "find . -maxdepth 1 -type f | wc -l" but there is also a difference to the original file and folder count. It doesn`t matter if the clients are connected via WiFi or Gigabit Ethernet. We have no access problems. We have the same behavior if we set the files and folders to 0777 permissions on the servers. The deletion of the preferences files of the users on the MacBooks does not solve the problem. If we use the "Go To Folder" option and type the path to a folder which is not shown in the Finder you get an result or not. But it is also possible that the result is not correct and there are also still files or subfolders missing.
    In my opinion this is a timeout problem and a "special SMB3 protocol interpretation" which is buggy. We have one hint found in /var/log/system.log:
    "Jan 23 14:35:49 wsosx33.clients.getcom.de KernelEventAgent[69]: tid 54485244 type 'smbfs', mounted on '/Volumes/customersdata2015', from '//x144067:@srvlxp013.servers.getcom.de/customersdata2015', not responding"
    We had no problems with Mavericks at all, we still have no problems with Windows 7 Pro/Ultimate, Windows 2008R2 (native or virtual) or Linux Mint 17/17.1 clients, neither with samba 3.x nor with our actual environment and different newer samba releases.
    We believe that this is a big bug in Yosemite, but we cannot go back to Mavericks because of incompatible TimeCapsule backups. Our workarround at the moment is that we have installed Linux Mint on our MacBooks to get 80% of our daily jobs done, rest has to be done with Windows 7 installed over virtualbox @Linux.
    We have no clue at the moment how to solve this problem, the samba logs do not give any hint. The access from other operating systems is perfect and very fast, but not with Yosemite. We checked different tips found in the internet but nothing helped.
    Does anybody has another idea to get Yosemite working or should we keep Linux Mint until Apple will provide a CIFS/SMB patch and going on with our workaround solution, which is productive at the moment ??? Our staff is not amused and wants one solution and not this workaround with two operating system. We have to decide wether we wait until Apple will get this fixed or we have to switch to Microsoft Windows (which is a No Go for me, but I will not be asked...).
    Thanks in advance
    C.

    Hi William,
    thank you for your response.
    As you can read in my post I talked about CIFS/SMB.
    It makes no difference if we mount the share over CIFS or SMB.
    Folders with lots of files will not be shown even if we use SMB3 or an older protocol.
    As mentioned I believe this is a timeout problem.
    Does anybody know how the CIFS/SMB timeout setting in Yosemite could be changed?
    Kind regards
    C.

    I have had the same problem. It was cured by turning computer off and/or restarting it. I am not sure  if once was enough. I think shutting down must cut out whatever it is that blocks bluetooth. Good luck
