connection client bluetooth (Android phone) to the server of VI

Hello, I try to find a solution to be able to retrieve data from my LabView (laptop) on my Android device. (Win7 x 64, LV2014 pro, Motorola MotoX Android 4.4.4)

I found the tutorial with source AppInventor2 example:

http://puravidaapps.com/btchat.php

It is a cat of BT base between two Android devices. The code seems pretty simple, but I'm not 100%... In any case, I've compiled an apk from this source and I tested it and it works between two android devices (Nexus7 tablet) and Motorola MotoX, all two a 4.4.4 Android.

OK, very nice, so now that I'm trying to "mimic" the behavior of the server Android, use LabView BT server, I have attached my test VI.

My Android phone is BT customer, I need to connect to the LV server with it.

So I start the server BT LabView VI to run it, and I have 10 seconds timeout, during this time I click "connect" on my Android app and select the address of my laptop BT (the laptop computer and the Android device have been previously matched, and the connection has been successfully tested with file transfer). However, the connection is not established, I get the error timeout 56 of the VI listener code (LabVIEW: the functioning of the network exceeded the time limit specified by the user or system.)

Maybe there is someone with more experience with BT / AppInventor and could help me how to connect and send strings to my Android phone?

Thank you

Best regards

new info:

I installed a terminal program series for my laptop Win7 and I put a serial port entering for my BT (COM 13) adapter.

I have also reinstalled the driver BT on my laptop. "Now I can finally connect my Android phone to the laptop and I see the message"User_xxxx"is connected" in the window of the terminal of the laptop. Also, I can send strings to the laptop of the android...

However, I am still not able to send strings from LabView...

Maybe I should try VI series? But I could only assign a serial port entering the laptop for BT, outgoing series is not possible...

EDIT:

I'm really a noob here, but I managed to make it work

I connect via BT, the laptop and the phone, and I connect to the laptop with the Android app that precedes.

I used the example LabView "continuous series write and Read.VI", and I am able to send and receive channels via a serial port COM13

    I am traveling and using my Android phone by Verizon to tie to the internet... This could be the cause?

    Hi BetheForcia,

    Exactly when you receive this error message?

    Usually, this can happen due to data execution prevention.

    In order to diagnose the problem, you can check in the event viewer to determine the cause of the error and after return with details of the event viewer.

    What are the information in event logs? (Event Viewer)

    You can try to add it in the exception for the prevention of execution of data and check that it works.

    a. go to Start, Control Panel and click on System.
    b. now, click on the Advanced tab, and under performance, click settings.
    c. click on Data Execution Prevention , and then select the Turn on DEP for all programs and services except those I select: radio button.
    d. now click on the Add button and navigate to C:\Windows\System32 and choose the regsvr32.exe file. When you receive the message indicating it could make your computer becomes vulnerable to attack and unprotected, simply click OK to continue.
    e. click OK , and then click OK to exit

    Hope the helps of information.

  • Direct connection on the desktop - clients still losing access when the server goes down or rebooted service

    I set up the connection to the server with a link Direct is TICKING, I did that once the initial connection has been made for the broker and an assigned desktop computer, connect directly to the desktop and so not care about the State of the connection to the server. After restart or just restart the VMware View Server service all customers lost access until it is facing up.

    Is it right, that we use View 3.1.

    Thank you

    It's strange that I can restart my server connection without worrying about all the users.   How brokers connection you have and do you have activated all at direct connection?

  • Registration of the Client Push BlackBerry rejected by the server

    Hi all

    Successfully, I registered for the blackberry push service assessment and received the appropriate credentials.

    However, whenever I try to save my client push service, I have developed with the help of a real device, I get a "rejected by Server error."

    I've only got my credentials 5 days ago, so I don't think that it has expired.

    I use a blackberry 9700 OS 6 to test this.

    The Client I wrote is a variant of the client Push service example.

    Here is the registration code.

    public void register() throws Exception {
            ApplicationDescriptor ad = ApplicationDescriptor.currentApplicationDescriptor();
            //byte serverType = PushApplicationDescriptor.SERVER_TYPE_BPAS;
            PushApplicationDescriptor pad = new PushApplicationDescriptor( PushConfig.APP_ID, PushConfig.PORT,
                    PushConfig.REG_URL, PushApplicationDescriptor.SERVER_TYPE_BPAS, ad );
            // check whether already registered or registration pending
            PushApplicationStatus pushApplicationStatus = PushApplicationRegistry.getStatus( pad );
            byte pasStatus = pushApplicationStatus.getStatus();
            System.out.println("Starting Registration");
            if( pasStatus == PushApplicationStatus.STATUS_ACTIVE ) {
                Subscriber subscriber = new Subscriber();
                subscriber.subscribe();//register again but don't block.
                System.out.println("successful registration");
                return;
    
            } else if( pasStatus == PushApplicationStatus.STATUS_PENDING ) {
                // we already scheduled registration, wait for its result
                print("Registration pending");
            } else {
                // not registered yet, register
                System.out.println("not registered yet");
                PushApplicationRegistry.registerApplication( pad );
            }
            parseRegistrationResult();
        }
    

    In the onStatusChange(), I have this:

    public void onStatusChange(PushApplicationStatus pushAppStatus) {
            byte bpsStatus = pushAppStatus.getStatus();
            byte regReason = pushAppStatus.getReason();
            String error = pushAppStatus.getError();
    
            boolean simChanged = false;
            _regStatus = bpsStatus;
    
            switch( bpsStatus ) {
                case PushApplicationStatus.STATUS_ACTIVE:
                    Subscriber subscriber = new Subscriber();
                    String result = "";
    
                    subscriber.subscribe(); //initiate subscription
                    result = subscriber.getResult();
                    print("result is "+ result);
                    if(result == "s") {
                        print("Whoop!")
                    } else {
                        print("we failed");
                    }
                    break;

                    switch( regReason ) {
                        case PushApplicationStatus.REASON_SIM_CHANGE:
                            simChanged = true;

  • Connect 2 or more phones to the SPA3102?

    I have a gateway SPA3102 - out with router (engine).  Using a double adapter into the phone jack can I connect 2 phones to it without damage?

    If I can do that is there a limit on the number of phones: 3, 4, or 5?

    Thank you.

    Rob

    Yes, you can connect 2 phones without damaging the SPA3102 FXS port if their total REN will not exceed 3 - this device can handle up to 3 REN (Ringer equivalence number)

    With most phones, the REN for the phone is printed on the phone itself (often in very small characters, however). Assuming you can find the REN of each phone (which varies generally between 0.1 and 2.0, depending on the type of phone), simply add the numbers (from all the connected phone line devices)

  • BlackBerry Smartphones Blackberry Media Sync continues to display 'Please connect a Blackberry smart phone' when the Blackberry Storm is connected to the PC

    About a 2 months ago when I would like to connect my (the first storm) blackberry storm to my computer via the USB cable supplied with the phone, I was able to transfer music from my computer (itunes) to the blackberry via Blackberry Media Sync with no problems (open Blackberry Media Sync, connect blackberry to the computer via the USB port and screen Media Sync would change so that I could sync to the blackberry storm music). I didn't even have to install Blackberry Media Sync in December 2009

    But now after I connect my Blackberry Storm to my computer, the screen of Blackberry Media Sync does not change and continues to display "please connect a Blackberry smartphone. I tried these tips I found online:

    1.) several reboots my computer (windows vista)

    2.) update/reinstall Blackberry Media Sync, then by restarting my computer

    3.) reconnection from blackberry to the computer, then open Media Sync

    4.) Open Media Sync first and then connect the blackberry to the computer.

    5.) installation BlackBerry USB and Modem drivers (even if I can't find the USB driver for it under the Universal Serial Bus Controller when I check in the Device Manager when you go to control panel – system and Maintenance – Manager of devices, but I found a v2 COM4 and COM5 RIM virtual serial Port when you select "devices by connection" under display in Device Manager) or are RIM Serial Port virtual v2 COM4 and COM5 drivers I'm looking for?

    6.) go to Options (on blackberry) - memory and make sure Media Card Support, Media Transfer Protocol (MTO) and Mass Storage Mode Support are resolved on 'On', the encryption Mode is set to 'None' and mass storage Mode Auto activate when connected, it the value "Prompt" although I tried to 'Yes' as well. It says I have 785 MB of memory space of the unit out of 879 MB total memory of the device and 7.1 GB of free space on a total of 7.3 GB of Media Card Media Card.

    None of the above tips and troubleshooting tips worked. I also checked the Blackberry technical solution center but I've not found anything there that has contributed to the other. I found discussions forums online, including issues of people with 'blackberry media sync cannot connect to the device' pop up, but I have not had this pop-up. The Media Sync screen remains just the same as if I never connected the blackberry storm to my computer in the first place even if my blackberry storm recharges via the computer.

    Is there something that I miss or have not yet done? What should I do?

    Too bad. I went to a Verizon store and they me remove the battery and turn the blackberry. Worked like a charm and I can now use Media Sync.

    Also told me that I need to update the software of the phone blackberry using Blackberry Desktop software (I have version 4 and need to update to 5) and make sure to choose to back up files when you are prompted during the update or you will lose all files, the media and info saved on blackberry.
