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 ")"

  • connected via WIFI, but the solution Center says printer 'not found '.

    Hello, when I first set up the printer, my router is using DHCP and assigned IP address to the

    printer has been 192.168.1.102. The range of IP addresses assigned by the router is 101-105. From time to time.

    I had noticed, the DHCP server sometimes assign an other addresses in the range to the printer.

    The printer is connected, the blue light on the front is solid, it is connected to the router successfully.

    But the computer cannot print it, there is no link status monitor HP is concerned.

    I thought that the printer should work with any address in the DHCP of the router range. I had to modify

    the router config to always assign 192.168.1.102 to the printer now all works.

    The printer is Photosmart D110.   Is this the way you would expect?

    Thank you very much for your answer, I'll keep the info as a reference.

    I've never accessed the printer through the web browser / IP before.

    In fact, I solved the problem in a different way. In my configuration of routers.

    I could add it the printer (using the name of HP928B0E - the apparent hostame)

    for the routers DHCP static table, so that the address 102 is always affected.

    I think static DHCP is a kind of hybrid between DHCP and IP static, but always using DHCP,

    but will affect only this address to the printer and not one of the other attached devices.

    What it is, it works for me.

    Enjoy - Dave

  • I have a Macbook connected via WiFi to a Canon MG7520. The destination of auto scan does not work

    I have a Macbook connected via WiFi to a Canon MG7520. The destination of auto scan does not work. I put it in a subfolder under photos. The box is there on this subfolder. (My older guns would use) But this scanner and the 7120 times insist on ignoring my selection and use of the pictures folder. (when I save, they won't have a record dated in photos, but I would rather not clutter it.)

    Nobody likes Macs.

    When you open the settings of the utility Scan IJ, there are 3 tabs at the top. The first tab is settings when the analysis is started from the computer, the second tab is for setting when the analysis is started from the control panel. Make sure that you change the destination folder to 'Save to PC (self)' on the second tab!

    I use the R7000 as a router and I have the problem that my UPNP renderer (Denon DNP-F109) is not visible if connected via WiFi (via Ethernet, everything works very well).

    Can someone give me a clue what to do here?

    http://Windows.Microsoft.com/en-us/Windows7/advanced-startup-options-including-safe-mode

    If the problem does not persist in SafeMode with network, perform a clean boot to see if there is a software conflict as the clean boot helps eliminate software conflicts.

  • EAS does not connect via wifi company post - 1.3.5

    This seems to be a somewhat different issue of EE that some know, so it was recommended that I start a new thread. My question: I can access is no longer to EAS via the wifi of my company. It worked before 1.3.5. If I turn the wifi off, I can then connect EE without problem. I get no error when connected via wifi, rather e-mail and calendar just don't update.

    It turns out that our firewall is configured to disallow connections since our internal wireless to internal resources through external access (that is, accessible through the Internet). This explains why it is not working currently - other devices exhibit the same behavior, including iPhones and laptops.

    The question then becomes: why it worked before? I can check before 1.3.5 I can be connected via wifi to my company and still connect to the Regional service. So the previous version tried to connect via wifi, then when he could not, did he switch to EVDO to connect?

    If this is the case, then it is a very nice feature and it would be great if it was turned off. If it is not the case, then I have no idea why it worked prior to 1.3.5.

  • Satellite C660-1RQ cannot connect via HDMI to the NEC projector

    Hello.

    I have laptop Toshiba C660-1RQ.
    It can not connect via HDMI to the NEC projector.
    I tried many drivers - the 268,57 (taken from the Toshiba site) to the new 331.58

    I thought, that it my problem, but the same lapto (my friend work - we have a few these notebooks in company) works well...

    And my HDMI works with monitors, TV (but sometimes!), etc.

    I don't know what to do...

    > And my HDMI works with monitors, TV (but sometimes!), etc.

    If s computer laptop HDMI port works correctly in relationship with other devices, I think that the problem is related to your laptop.

    What happens exactly when the projector is connected? Can you pass to the external video using the FN + F5 key combination?

    The use of Fn + F5 keys can toggle between internal and external display.

  • HP LaserJet 1200: HP LaserJet 1200 connected via USB to the PC with Windows 7 is not redirected in DRC

    Hello.

    HP LaserJet 1200 connected via USB to the PC with Windows 7 (32 bit) and works fine (latest drivers via Windows Update installed).

    But when I have connected via RDC (Remote Desktop Connection) for PC with Windows XP and try to print from this PC to LJ1200 - it is not redirected in a remote desktop session and I did not see in printers and Faxes folder.

    Other printers from PC with Win7 works fine via DRC (XPS Document Writer and PDFCreator).

    During this time when I do the same thing from another PC with Windows XP, LJ1200 (connected via USB to the PC) works very well through the DRC.

    Anyone know how to make LJ1200 to be redirected in a remote desktop session?

    Thanks in advance.

    For more information, here are 2 possible solutions:

    1. put two computers in the same workgroup and then share the printer and install from the remote computer.

    2. best solution: install on PC with Windows 7 drivers for Windows XP (PCL6) - it works very well as a redirected local printer via DRC!
