Part Number: LAUNCHCC3220MODASF
Other Parts Discussed in Thread: CC3220SF, CCSTUDIO

I have been working with a LAUNCHCC3220MODASF with two of them, and have been trying to make a communication between them.

when I make "at+connected" to the socket I get error "ERROR: process command,-111". the first process is AP and the second process is STA.

I have been success to make a connect between them but i can't sending data between them. Any help???..... please see the picture.

thank

Hi Mostafa,

For TCP communication, the server needs to first bind and then listen on a socket before you initiate the connect command on the client side. Once the client has started the connect request, you need to accept the request on the server. Then, you can use the newly returned socket on the server for communication back to the client.

The tcp connect flow and the commands you should send on the client/server can be seen here:
processors.wiki.ti.com/.../CC3200_TCP_Socket_Application
I suggest you take a look, and follow that flow on your client + server and see if you can get the TCP connection working within the AT command example.

Regards,
Michael

Hi Mostafa,

If you could share the exact commands that you are running on each CC3220 LP, that would be helpful. By looking at the commands you are running, I will be able to see whether you are doing anything incorrectly, or try out the connect + send/recv sequence that you are performing and test to see if there are any issues with the application.

Thanks,
Michael

Hi Michael,

Sorry for delay, last two weeks I decided to change my code in cc3220sf, and i didn't success to keep my new program in cc3220, after hitting reset (or re-plugging USB) the program get deleted. I have been used CCStudio.

Hi Mostafa,

It looks like the issue in your other thread is separate from the issue in this thread. We will be helping you with your flashing issue in that thread, but I will be closing this thread as it seems like you have moved on from the AT command issue you were describing in this thread.

Let me know if you need more clarification on the AT command example or have further questions on this topic.

Regards,

Michael
