• TCP/udp connection via the private wifi network

  I want to develop applications using the wireless private network with tcp/udp connection for my Blackberry 8320 (Version 4.2.2.180 without SIM), do I need authorisation from RIM so that they work in the unit? If it is true, how can I get permission?

  I noticed http://www.blackberryforums.com/wifi-hotzone/100800-8320-wi-fi-limited.html

  who says:

  "The Blackberry 8320 with wi - fi connection is limited. The only program that can use the wi - fi is the Blackberry browser... all the third-party programs... ie. Opera Mini, JiveTalk and even RIM's instant messaging programs. Yahoo Messenger, Windows Live Messenger, are all designed to connect using data from EDGE of the phone... None of them can detect or use the wi - fi! »

  If it is true now?

  You can use the interface = wifi parameter in the URL to specify that the connection should be performed by Wi - Fi.  However, please note that this setting is available in version 4.5.0 and highest BlackBerry device software.  Therefore, you must first put your BlackBerry handheld.  FURTER details can be found here:

• UDP connection via wifi in the name of 8320 tunnel met IOException:Invalid

  I am new to Java, trying to open a UDP connection on wifi in my BB8320 (V4.2.2.180).

  I have connected to my 8320 to a WiFi network and that you can access Web page in the browser (configuration: Wi - Fi browser).

  I tried with: Connector.open (DatagramConnection) (datagram://192.168.1.101:5009) and Connector.open (DatagramConnection) (udp://192.168.1.101:5009), but all got IOException:Invalid name of the tunnel.)

  Here's my Mobile Network Options in the camera: Data Services - on; Connection preference - Wi - Fi only.

  The same code works fine in the emulator, tested in a wired network.

  I googled this IOException, it seems that the TCP APN cannot be null, I tried with blackberry.net cmnet, wap.voicestream.com and even the name of the Wi - Fi connection, everyone met time-out problem.

  I have some questions below:

  1. is there any configuration that I missed?

  2. the UDP connection via wifi check the AFN? The APN configured in the emulator is null.

  3. do UDP and TCP connection API need permission in the device?

  Appreciate for any suggestions!

  I did in the past, and IIRC the trick was to add: «;» interface = wifi; deviceside = true"to your connection string. for example:

  Connector.Open ("udp://192.168.1.101:5009; interface = wifi; deviceside = true ")"

• A lot of ghosts UDP connections

  Hello

  I noticed a huge amount of visible connections by our PIX (running 6.3 (3)). They are all connections, apparently because of DNS traffic. "See the conf:

  UDP on 65.110.41.70:53 in 158.64.1.14:2656 idle 0:00:05 flags.

  (several thousand)

  158.64.1.14 is our DNS server. That the DNS server perform a query looks like this:

  11:31:33.291565 158.64.1.14.kana > 65.110.41.70.domain: 3774 [b2 & 3 = 0x10] A [1]? New.awjicomfort.com. (48) (ttl 64, id 42281)

  The DNS that is being queried server does not respond to something, so it would be normal to have UDP connections, but the amount is not anywhere close to what it should be.

  An approximate count gave me that the DNS server sends queries to the external server to a rate of about 4 requests per second (different queries on the same server). However, the connections see show rather 50 connections whithin a second (based on idle time displayed).

  Does anyone know whence this difference? I ca. 65000 connections ghost, due to the 2 servers DNS querying the same host.

  Edit: UDP timeout has the default value (0: 02:00)

  Gilles

  Gilles,

  Looks like a known problem - CSCec45748 - new DNS & reset the timer of inactivity of the previous DNS &.

  The crux of the problem (as you can see from the title) is that of the existing DNS downtime & are reset when the new DNS & are established. Suggestion at this point would be to go ahead and prosecute TAC and get the latest version of 6.3 (3). This problem has been corrected and checked. Sorry for the trouble.

• Localhost UDP connection between FCR and Matlab

  Hi all

  I have a question about the connection between Matlab and FCR UDP. My idea is to Exchange data between Matlab and Labview on the same computer.

  So I found the 'UDP Simple' of the FCR 2.0 sample project where periodically a datasample is generated randomly and sent to the remoteport 61557 local host. In the project a 'fractional number of string for transmission' is used for the transmission of data. The receiver of the sample project reads from the same port to receive the datasample.

  Now, I'm interested to read this simple stream from Matlab (just at first), however, it does not work and I'm not sure why. What I do in Matlab is the following (code Matlab)

  delete variables;
  u = udp ('127.0.0.1', 61557); % Of installation UDP Object
  fopen (u); open reading port %
  A = fread (u, 1);  % read an element
  fclose (u);

  With this code, however, I get a timeout by saying: "' WARNING: unsuccessful reading: the amount of data specified has not been returned within the time limit." "

  I'm not sure why this happens, maybe you could help me out here? I guess that the formet serving to VCF is not the same as in Matlab? Maybe the Terminators are not the same?

  See you soon,.

  Hey

  So, regarding the problem actually, I found the solution today. It was not the firewall, but a simple configuration in Matlab seting the UDP port. So the side of Matlab, to change the definition of udp object according to

  u = udp ('127.0.0.1', 'Thelocalport', 61557);

  If you have

  u = udp ('127.0.0.1', 'Thelocalport', 61557);
  fopen (u);

  A = fread (u)

  fclose (u);
  Delete (u);

  Who does the trick and you can read from the port. Then of course you say Matlab that you read from the "LocalPort" x, which I wasn't aware of.

  On the transmitter side, you simply:

  u = udp ('127.0.0.1', 61557);

  fopen (u);

  fwrite (u, '1');

  fclose (u);
  Delete (u);

  Here, you set just the port of transmiting.

  About the format of the data: I used the simple UDP protocol streaming Comms project where a random number is generated as a double, transformed into a string (ASCII values) and transmitted. At the level of the receiver, you get as much the UDP packet with the ASCII values that you must turn if you want to find the number.

  I hope this helps anyone having the same problem.

  See you soon

• cRIO 9082 - cannot connect through NI MAX/LV

  Hi all

  I am writing my bachelor on the dynamic memory and the vibration tests.

  The project I design an experimental platform used to excite some mechanical components.

  We need several sensors (MON, accelerometers, DC motors etc.), we use a cRIO 9082.

  However, when I want to connect to the cRIO I can't OR Max, that is I can't set it up. I can see it only in the browser OR (see photo).

  I am connected directly to the cRIO via a crossover cable and IPv4 is set to automatically assign the IP address.

  Any ideas of how I properly connect to the cRIO 9082.

  I'm new on the job with this kind of electronic products, since I am majoring in mechanical engineering - so please keep the explanations as simple as possible ;-)

  If you want more details, please let me know.

  Thanks in advance.

  JZaulich.

  Hi Alex,

  Thank you very much for your answer.

  I had to disable the Windows Firewall as well as the AVG firewall, that did the trick.

  Apparently Windows does not allow this type of connection.

  After you turn off the firewall, I added the cRIO using the IP address, and it seems to work very well.

  Thanks again.

  Best regards

• Info volume cRIO 9030 to connected USB drive

  I want to display the available disk space for a USB stick plugged into a cRIO-9030 running Linux Realtime (path to the drive is/u).  It is a data logging application that can run for a month with users looking only to see that things are run OK, which they won't if disk space wears.  I tried to get information of Volume and the file Info screws, but both give me nonsense values.  It seems that the Volume of information VI get always reports on the internal disk (/ C) any way I use, I can't see how much space I have on the drive/u.  I plugged into different USB drives with different capacities and free amount, but I still get the same values of the VI, which differ from what MAX brings to the reader/c, but are the closest values for this player than anything else.  I also get a useless value of the VI of information from file/Direcory, which seems to be pointing out how many files is at the root of the drive, not its quality or its free space.  Any suggestions about how to get free space and capacity of a USB key connected to the cRIO?

  bjlv

  Odd. I just tried this on my own target RT Linux (running LVRT 2014) and it seems to work as you expect, where to get the Volume information on ' / u ' returns the available space on the Flash DRIVE and is certainly different from what I get from the internal drive. I see a bug (?) where there's just ' / ' was not taken in charge, what should be on Linux:

  

  / (or/u) u is actually a symbolic link to where the drive is actually mounted as/media/sda1 or/media/sdc1. (/ u is provided as a convenience of compatibility for porting the applications of Phar Lap or VxWorks.) You get the same result using the actual mounting location? You have access to a shell to the target? If so, that shows "df"?

• TCP (UDP) connection with Blackfin

  Hello!

  I BF-537 EZ - KIT Lite and I'm trying to create a simple server in there. I found following problem: listening TCP port does not respect the time-out: it waits until the client establishes the connection for always (value of timeout regardless). Same thing happens to «UDP read» In addition, these screws completely block the execution so the parallel loop is thus blocked. I've found the workaround: If you wrap all timed loop loops, they run all in parallel; the connection listener is still stuck and waiting forever, but the other loops run.

  Is TI WHEREAS behavior? Suggestions to combat it?

  Thank you!

  
  

• FPGA for PC via UDP connection

  Hi all

  Background

  I am currently working on a project to interface an FPGA with a PC, to send a UDP load prepared on the FPGA for the PC. The FPGA is preparing a payload of 18 hexadecimal bytes from h00 8' to 8' h11 and then transmits it via a local network on port 1024, between the FPGA and a second network card in the PC, with static IP assigned to the second network card and the FPGA. Packages leave the FPGA and reached the PC (tested with wireshark) but the vi does not appear meet the payload and display it on the screen in the vi. The vi is based on that comes with labview and only has a few adjustments for most simply to write the final packages saved to a text file.

  Problem:

  Initially, when the vi was run the length of the chain kept evaluate to zero and so he perceived no bytes don't read from the port. I then inserted the flatten channel vi after the UDP read and before the comparison of string length (after reading something on the forum), now the length of the string is not evaluated to zero to 4 instead of this, I also changed the display to the spell option but the same 4 Hexagon keep coming through '0000 0000 0000 0D0A' , but they are not those who have been sent from the FPGA (are they an error message?) and not those taken over by wireshark. In summary, I seem to not be able to read the data of the UDP payload in Labview.

  I tested the VI locally using the Protocol UDP send labview vi and vi (slightly) custom receiver and it still works. The receiver that VI is attached.

  Any suggestions would be great,

  Thank you

  James.

  You can share the wireshark log (preferably in a format based on text that I did not install Wireshark)?

  Are you sure that is no firewall problem? If you are using a firewall, disable it completely for this network card or at least ensure that it accepts connections on UDP Port 1024.

  In addition, set the UDP sender VI on another computer and see if you are still receiving data. If it works, compare logs wireshark compared to what is sent by the FPGA and search for differences. If this does not work, then you have a network like a firewall problem.

• required firmware on cRIO for UDP Multicast

  Hello

  I would like to run this excerpt on a cRIO system:

  (open a port for the UDP multicast messages).

  On a standard PC with Win7 that it works, I can send and receive messages without problem.

  But on a cRIO, I get an error 54 ('bad network address'). Until the devil?

  The cRIO is implemented with this software (LV2011SP1):

  

  I want to reduce memory consumption, so chose not to install the recommended all packages.

  I suspect that there is something missing. Is what part of the package?

  I found a solution (or is a workaround solution?)...

  Need wire entry "network address" Open UDP service. It seems that the cRIO does not know that it is the own IP address:

  

  A correction more: you should only use "String to IP" on the cRIO. When used as indicated above, it gives error 54 on the PC! Arrrgghhh...

  The following solution: put the StringToIP node within the ConditionalDiagramDisable structure already in use

• How to detect if the cRIO modules are connected

  I have a FPGA code that streams of data a 9219 and 9239 module. I want to disable this code if the modules are not connected. I tried looking for the values 0 to the Module ID and serial number, but no one who seems to work. What method or property questions in LVFPGA to see if the module is connected?

  Check an error output on the node of FPGA IO of the particular module. If I/O is not existed, it will give you an error.

• connection intermittent cRIO (with MAX, etc.)

  Our cRIO connects to our fine PC when it is initialized at first - and you can view it fine in MAX, Manager of distributed system and its web interface. But after all 3-5 minutes it always loses connection. It remains disconnected, and only restart the cRIO restores the connection but only for another 3-5 minutes. Only MAX restart does not help. We can ping the cRIO ok when 'disconnected' - which, to me, implies that it is a problem of higher level software.

  We had this particular cRIO work fine before.

  Thanks for your suggestions... While not in a rush to do this, I really want to understand why the connection is intermittent

  Here are some details:

  • MAX version 5.0.0f1
  • LV2011 DS2
  • cRIO is a 9022 (no screws running on it to the commissioning, CPU minimum load - idle = 97%)
  • computer development is a Vista Home Premium 32 bit
  • connected together using the brand-new Cat5E cable
  • TCP/IP settings on the laptop - Static IP, IP 192.168.2.4 address, mask 255.255.255.0
  • TCP/IP settings on cRIO - Static IP, the IP 192.168.2.1, mask 255.255.255.0 (gateway and DNS are blank or 0.0.0.0)
  • cRIO set to use for the link speed autonegotiation (no option to change this) and detection of packets = "interrupt".
  • PC value link autonegotiation speed, but has no effect on the problem, if it is set on a fixed, low speed for example. Half-Duplex 10 Mbps
  • PC Firewall is configured to allow the port 3580, and actually disable the firewall altogether change the problem

  Had the chance to try again with my intermittent connection to cRIO, and here's what I found:

  • Connection through a switch, rather than directly with crossover cable - made no difference, still kept disconnecting after 3-4 minutes
  • With no other network on my laptop other than the LAN - no difference development
  • cRIO with APP No. dip switch select IT - no difference
  • cRIO with game of dip-switch SAFE MODE - this time it is remained connected, but this mode is not very useful as a solution

  Then I was reinstalling the software cRIO as suggested - it did not complete the first time, but second attempt was beautiful and connection is now very stable (and has not abandoned in the last 30 minutes).

  Here are the instructions to reinstall (just in case useful for others):

  1. In the measurement and Automation Explorer (MAX), access remote systems | cRIO | Software
  2. Click on the "Add/Remove software", and an installation wizard will appear
  3. With currently installed version of the selected software - "then click to reinstall the software currently installed.
  4. Follow the rest of the instructions, and it should take about 4-5 minutes

  Thanks for your help
