TCP transfer data between two Q2438F module


#1

Hello.
Excuse me, i will transfer data from Q2438F to another Q2438F module via TCP Socket. How am i to do? Thanks a lot.

Do you have the related software programming guide for the Q2438 TCP/IP stack? That should be the right starting point. If you don’t have it, the entire developer document set for all Wavecom products will be available on a brand new website with a brand new Developer Zone and account profile, to be launched at the beginning of December (2007).

How will developers get access to this?
I mean, do we have to get an account through our distributors or can anyone sign up for access?

And, most importantly of all… Will we be able to get the latest SDK’s and firmwares from this new site? Will roadmaps for SDK and firmware updates be available? (Roadmaps change all the time but even a vague idea about when something will be available is better than not knowing anything at all.)

Also, will there be any feedback system available? Going through distributor for bug reports or other technical questions is not really optimal. I understand the need to filter out beginner questions, but I also think there is a need for more advanced developers to have a good way of communicating directly with Wavecom at times to resolve various problems.

I’ve been developing OpenAT and ADL applications for about 3 years now, and this is the best news I’ve heard in a while.

Maybe we should move this topic somewhere more visible since it’s gone off the original subject but here goes:

  1. The new site will allow existing developers in the current forum to upgrade their account to have access to a developer extranet of the main Wavecom site (official details on how to do this will be posted in the forum on or around the first week of December).

  2. New develoeprs will be be able to create a new account that has unified credentials that provides access to be the forum and the extranet. Login and account creation links have been placed very visibly on the new homepage.

  3. Most significantly, there will be no arbitration of who can/cannot create an account and the whole account creation process is automatic and instant. You only need to provide a valid business email address to receive your account credentials.

  4. Developers with an extranet account will have unprecidented (and rightfully so) direct access to documents - intended for developers! This will include:

  • Latest hardware specifications and design guidelines
  • Latest Open AT Software Suite (formerly known as the Open AT SDK)
  • Product Certificates
  • Application Notes, some with source code for larger apps
  • Multimedia presentations
  • Product flyers & photos
  1. There will also be a new Developer Zone which Wavecom intends to expand over the months following hte initial launch and we encourage developers to tell us what you need in that zone.

I hope you will be please with the changes!

Taking your other points:

(a) Roadmap: There is no plan to make a roadmap publicised in a public place. When a company is in a leadership position, this is not seen as a bright move. But, see point © below.

(b) Technical support: Technical support will continue to be provided via the Wavecom value-added distribution channel. There are literally 10’s of thousands of customers worldwide and that’s why the distribution model works most efficiently. However, I’m sure you can appreciate than many problems have been solved in the forum cummunity and note also that there is a feedback loop back in to Wavecom to correct documentation and product improvements that are seen on the site.

© Access to Wavecom R&D is something that has been started on a small scale just recently. The Wavecom Developer Think Tank started a few months ago and takes ~10 of the most knowledgeable Open AT developers and brings them to Paris to enjoy the sights, food & wine, in addition to sharing roadmap information, trying new products before they are released and even getting to sit in front of Wavecom developers creating the products you work on. This runs 2 times per year and is full for the next session but if you’d like to be considered, drop me a personal message with your name, company, country, products you have developed and with what Wavecom products.

I also have this problem.
I try connect each other between two q2438f module using embeded TCP/IP stack. But the result is not success.
Q2438f’s Tcp/IP stack can only create a client socket , but TCP/UDP need Client and Server, q2438f .

I think The embeded TCP/IP of Q2438F need adding socket server function.
so, you can do is waiting for software update Or you do it by yourself.

you can program TCP/IP/PPP code in your host,
two module A and B,
First, Module A use UART1 with your TCP/IP/PPP code go to online, then get your IP_A of Net gived dynamicly.
secondly,A creat a server Socket to litsening any connect.
Thirdly, A use UART2 with AT+CMGS command to send a SMS to B, tell B it’s IP_A .
when B have recieved A\SMS , B goto online,get IP_B, create client socket to IP_A,
Then, all works to be ON.

What TCP/IP stack are you using?!

WIP certainly supports both Client and Server sockets!

Unless you have a public IP address, I don’t think there’s any guarantee that this will work?

You might be lucky, and find that your devices just happen to be effectively on the same “private” network - but I don’t think there’s any guarantee that this will generally be the case?

Is there… :question:

What TCP/IP stack are you using?!
My host system is Linux based ARM9.I use Linux PPP stack.

Unless you have a public IP address, I don’t think there’s any guarantee that this will work?

In china, China Unicom Company take public IP such as 211...*

WIP certainly supports both Client and Server sockets!
I use Q2438F module. Please tell me how to use WIP creat a server socket to litsen a connect. Thanks!

Well, that reply was extremely hard to read!

You block-quoted my entire post, and then included parts of my reply again with no indication of which bits were mine, and which were your replies!

Did it look clear to you?! :open_mouth:

What has your host system got to do with it?!
You were talking about the Q2438f’s Tcp/IP stack!!

OK - but in general, most GPRS networks do not give public addresses - so in general what you said won’t work

That is all clearly described - with examples - in the WIP User Guide.

Please tell me. Is the WIP q2438f’s embeded TCP/IP stack? where can I find the WIP & User guard? Thanks!!
