Create Bluetooth earpiece function only works in some cases

The function create a listener Bluetooth generates an ID of listener that lets wait for an incoming connection of Bluetooth. Because every time that you run a VI that contains this function, it must create a new listener ID, otherwise the block following that wait on the listener will crash.

I found that for the listener to create function work properly the entry that the Service Description must be connected to a control element. If its connected to a constant run only once, then creating a new id of the listener, but she keep this id indefinitely. In this case, you will need to close all the screws and reopen to be able to run the function again.

(See attached VI for an example.)

Can someone tell me, why is this? Is there a difference in the compilation/execution screw using controls instead of constants?

Thank you!

I could reproduce the error. I presented a report to R & D. I'll let you know when I get a response from them.

For now, you can try using a control instead of a constant and make it invisible in the façade.

Kind regards

Georg

    Do you mean that you have no web sounds? If so, make sure "Play web pages" or similar is verified in any browser you use.

  • Form with active user rights only works on some machines.

    I created a pdf file that contains video media. For this I have attached an acrobat form created with extended user rights. When send a certain number of respondents, some are able to open and fill out the form, and then return the form (in pdf format) while others experience a message "this operation is not allowed.

    The pdf of media is created in Acrobat 9 pro on the Windows XP platform and the form in Acrobat as well. The form has three drop-down menus and the three fields to fill.

    If the form is sent on its own, everyone is able to access.  It is only when the form is sent as an attachment to the pdf of video media that this is a known issue. The pdf file must be retro-compatible with Acro7.

    My problem is that I do not understand why it works with some and not others. (These are not coprorates but people.)

    You will appreciate the help. Date deadline has passed.

    For use with Acrobat you don't need extended Forms user rights.

  • Scanner only works on some computers

    I recently bought a Canon LiDE 220 scanner which is supported by El Capitan according to apple of supported scanners page, but whenever I try to scan on my computer it says "Scanner reported an error. Cannot communicate with scanner ". I installed the Canon software before you try to analyze, and I wonder if that's a problem because it works on two MacBook Pro (Non-retina display) without the Canon software. I restored my computer from a time machine backup I made before I installed the software, and I still had no luck. Any ideas?

    So in summary:

    Does not work on MacBook Pro (Retina Display) OS X El Captain with or without software and drivers from Canon.

    Does it work on MacBook Pro OS X El Captian without Canon software.

    I tried to use a snippet, page printers and preferences system, Capture of Image Scanners and scanner Canon proprietary application all to nothing done.

    Has anyone run into this or know why it works on some computers, but not mine? I love a fix or work around.

    Thanks in advance

  • Control values defined by the Index function only works for a running VI?

    I've never used set of control values based on the Index before so I decided to compare it against two other ways to set the controls on the front panel, by using the invoke Ctrl.Val.Set node and nodes for the value property. But if the VI which I am trying to set the controls does not work I get error 1000 say "The VI isn't in a State compatible with this operation." When I run the VI which I am trying to set the controls, I get an error. This is VI really only work if the VI is running? I can't set the values before calling the VI to run dynamically?

    I wonder why you do so in the first place.

    a bit of history. This feature was added to the problem write to items in front by reference is about 1000 times slower than writing to the Terminal. I think that this feature works by writing directly to the transfer buffer. It always ends up by being slower than writing to the Terminal, but only about 10 times slower.

    My company made use of this new feature. We needed it because we have updated thousands of values of frontage on the same VI by reference and labview couldn't keep it up (Yes, probably could have worked around him in a different way, but there is more detail than this...). If your ' e does not update thousands of articles, probably you should not use this feature. Performance savings is not worth the additional development effort it takes.

    It does not work probably because the transfer buffer does not exist when the vi is not running

  • Wi-fi/lan connection only works on some devices

    Hello... I have problem with wi-fi/lan connection. I work in a school with about 100 children. The problem is that some computers/phones/laptops can connect normally to a connection wi-fi/lan but some cant. The internet icon actually shows normal connection, but you cannot browse the internet. When this happen the only thing I can do to help temporarily change the mac address of the device with software changing Mac and which usually resolves it. So maybe the problem is that too many devices are connected at the same time or mac addreses interfere with each other or something. I have tried almost everytnig, reseting routers, change the settings of the router, changing channels, etc. of mac filtering... It was working fine before. Maybe you can help. P.S.

  • sharing is only working for some websites of Internet connection

    Wi - Fi my laptop is steady as a rock, but the wireless adapter I have for my office to cancel very often, so I decided to connect both via an ethernet cable and use internet connection sharing so that the Office can enjoy wireless laptop. Both computers have Windows 7 Home Premium installed.

    The Installer seems to work, but only for some Web sites - for example, it has no problem to connect to google and microsoft.com using ICS, but he absolutely refuses to connect to facebook but also many other Web sites. My laptop has no problem connecting to websites that my office cannot connect, so I'm puzzled as to why it seems to be able to relay connecting to some Web sites, but not others. Can someone help me understand what is happening here, so that I can access more than just pieces of the internet on my desktop?

    I'm sorry, but you can understand how annoying it can be when someone does not even time to read your question and posts nothing but completely irrelevant, canned solutions (who would would realize that they were not relevant if they had taken the time to read it instead of just copy - paste * based on the title of the post). It's worse than no help at all, because then people who might bring if not actually useful assistance will see oh, "this question has already been answered" and move to one that was not. In any case, I'll try to ask in this forum. Thanks for the suggestion.

    I am currently using an iPhone 6.  Have you tried a couple of bluetooth headset, but have had some problems. The Motorola I redials the last number, I called instead of start Siri when I push the button. Does anyone have recommendations? Thank you!

    To be honest, it's really preferences. You would have to research which devices are supported, Siri, if that's important to you. I know that my blue Ant T3, and it also stores my contacts list. This means that when the phone rings, the unit actually announces the caller's name, and I can give a voice command to answer if my hands are not free.

  • DateTime liquid switch only works on some browser form input fields

    I have a form of agreement where I would like to have the current date is displayed only (readonly) in the form of entry.  This will display the date perfectly well a range of browsers and OS but my client always reports that the form field displays the date + time (22-June-2015-12:00). Apparently, it still shows 12:00 for the time. I was unable to reproduce it in any of my tests with several browsers and operating systems.

    That's what I wrote to add the date:

    {% assign dateVariable = {{globals.site.dateNow | date}} %}}

    It's weird.

    It will not be something to do with the browser because liquid is script server-side and today's date is server only side not the client side too.

    | date displays only the date but not the time, and I did not add time.

  • Problems with Firefox 13. Cannot see the drive of audio files online. Video only works on some sites. Everything works OK or update Flash. No change

    The problems started when Firefox updated 13. tried to download the latest version of Flash 11.2.202.235. No change.

    Video works sometimes on YouTube, not at all on most of the other sites.

    Audio player not working do not at all. Not yet visible or Real Player downloads against playing within the application like Amazon.

    Tried to turn Add ons to find the culprit. No luck.

    Just as there should be in Internet Explorer.

  • Share to Youtube function only works do not (first Elements 8)

    I just buy Premiere Elements about two weeks ago.  I have successfully downloaded two videos on youtube and they worked like a charm.  Today when I go through the share button to load a video on youtube, when I hit next, nothing happens.  The action area of the program seems to freeze and I can't choose options.  After a few minutes, an error message appears that says:

    "Online services encountered an error.  The service will now be terminated or suspended if possible. »

    Has anyone else had this problem? Do you have any advice on how I can make it work?  I tried all the presets on part (HD, 320 x 240 flash, etc.).  Voluntarily, I bought this program to get rid of the save-file-to-pc-and-from-there-log-in-and-upload-to-youtube process.  REAR, how frustrating!

    Thank you for your comments!

    Brad,

    Welcome to the forum.

    As a test, I share the timeline for a preset of YouTube, and then try to manually download this file which results in YouTube. Does it work?

    Note: I've never used PrE 8, so don't remember exactly what might be the YouTube Presets and has never used the features of direct download - I've always used a workflow, as I've mentioned in this 'test '.

  • Satellite L20 modem does not work in some cases

    Hello

    a friend bought a Satellite L20 last summer. In January, she started working on the Internet on an irregular basis, but has known trouble. So I looked after the laptop last week:

    When you try to connect to the Internet connect to the provider sometimes fails. If she finally gets the connection, it often occurs the message that the page could not be found, and only after clicking on the button "Refresh" the page several times finally appears. But oddly enough, every time I unplugged the power supply connection become noticeable better.

    (Win XP; pilot/diagnosis: no problem arose; provider works very well on different computers)

    Unfortunately, he had no chance to check the connection here with a different material. I can't say if the latest driver is installed, but think that Yes, because of the date of purchase. So, my guess is that the power cable is not adequately protected. But if so how? Or what else could be the reason for the unexpected behavior of the modem?

    Thanks for your suggestions!

    Hello

    I heard a similar problem with another model of Satellite. Solution was to install the Satellite A110 modem driver. Please don t ask me why, but test it.

    The modem driver, you can find HERE

    Good luck!

    But you are confused "numbers" and "ropes"... of course, to a human being, 03 and 3 are the same - three. But at a computer, '03' If a string is NOT the same as "3". These are different things, and the 'numbers' in the string are simply characters.

    '03' is between '0' and '21' because the first character in the string ('0') enter in the range ' 0 'to 2'. "3" is not between '0' and '21' because '3' is not between the range ' 0 'to 2'.

  • I've updated to Firefox, The Free Dictionary has lost some essential features, cannot get back them. The DFT now only works in English. What should do?

    I updated Firefox to 10.0.2 and lost the functionality of The Free Dictionary. I reinstalled TFD, but now it only works in English. Say I read a German Web page, highlight a Word, the dictionary will seek in the English Dictionary. Before that I had all the versions I needed, and the dictionary automatically in the right. And before that I could have the toolbar installed, now there is no option for this either. What should I do?

    Maurizio salute, I asked you to a problem with the free dictionary. I found the solution, which in fact was not technical. In case someone else has the same, that's what I did not understand: when I highlight a word in a text in a language other than English, the dictionary gives me an explanation in English, i.e. 'not found word', but when I then press 'Search', the dictionary connect in the appropriate dictionary. It works even in Chinese! So, problem solved. The dictionary is not as good as before, but still, it works. Best regards, Markku
