I have also used the pc ip address with no luck either.. This results in bad request and not connection refused..

and used a different ip address and now get timeout.. I think this is the one I will concentrate on..

Are you using an emulator? If yes then use this ip address to connect to the pc: 10.0.2.2

127.0.0.1 points to the device. It will never connect to the pc.

You can use the pc ip address, however Windows firewall blocks incoming connections. So you need to open the port for incoming connections.

Because of the firewall issues it is simpler to let the device act as the server.

Hi Erel

I have disabled my pc firewall still with no joy. I need to be able to debug the VB interface which receives the request from the device so need the pc to be the server. I have just set a vpn up on the device but still cannot see my pc. I saw there is a way to debug a site with visual studio so may upload the files to my actual server and see if that is a solution.. Thanks for your help..

Derek.

Hi again..

Still troubled with this issue.. More information for you to maybe assist further.

I have created a Web API in Visual Studio.
I have created an app on B4A and run it to my device to debug it (not emulator).
I want to debug HTTP requests sent to my web API which is on my pc.
I tried attaching to w3ww.exe in my VB API to catch any requests incoming.

No luck..

Any ideas what I can try to solve my problem? I have a log of debugging to do and would like to use my device and send requests to my API running on my pc..

Thank you

Try to open the link from the mobile browser to see whether there is a network problem.

You can also try this B4J + B4A example: https://www.b4x.com/android/forum/t...ceive-objects-over-the-network.34612/#content

Hi Erel

No luck... I get a 'bad file number' when I press connect. (fcntl failed)

I have IIS running on that IP and can see the IIS default page when I type it in my device browser..

Thanks again..

Do you get this error with the B4J example?

Sorry, I have not run the B4J example.. I am pretty sure it is my pc and permissions/IIS causing the issue. I am happy to continue right now and test the sending independently to the receiving, and merge the two later on..

Thank you for your help on this, and sorry if I contact the forum again about this in the future..

Derek.
