MSP432E401Y: Need a TCP Client implementation

Punith Salian

Part Number: MSP432E401Y

Hi,

I wanted to implement the TCP Client on the MSP432E Controller. The examples that are part of SDK implements TCP Server Echo.

I have tried to modify this example code to make it a TCP Client Echo Code but not able to do it.

The changes I made include removing the bind() and the listen() process and instead include the connect().

I am not able to implement it though. I searched through a couple of posts here in the forum but none of them specifically give a solution.

Let me know if there are some existing codes that act as TCP Clients or some reference material to do so. I am referring through the TI NDK API Manuals but still not able to get the code going after trying a couple of things.

Thanks & Regards,

Punith

There might be similar threads but none of them gets to the resolution and guides to implement.

Hi Punith,

The tcpSendReceive.py python script acts like a TCP client for this example. Although this isn't coded for you in C. It's using the same standard socket interfaces that are enabled on the platform. You should be able to modify the code to get the same behavior. Is your end goal to have an http client? (or are you planning to communicate over some special port with a custom protocol?)

Leo

Leonardo,

I want the MSP432 firmware to implement a TCP Client code. The current SDK code has TCP Echo code which is a TCP Server firmware (Provided as an SDK example)
I am implementing a MODBUS Client ( In the MSP432E ) as the end application for one of the projects.

Thanks & Regards,

Punith

Hi Punith,

We don't offer a standalone code example for a TCP client on this platform. We do, however, have an example which sets up an HTTP client connection over a TCP client connection which can be found here:

https://dev.ti.com/tirex/explore/node?node=AAVpU4ifZYrmT.jG40doog__J4.hfJy__LATEST&search=MSP432e4

You can find additional code examples that will run with the lwip stack on this platform here:

Thanks Leo.

I will look into the links suggested by you.
lwip stack might provide some solutions but need to port it to the TI SDK based firmware implementation.

Hi Punith,

There is a myTCPClient example in the lwip open source project I sent you. This example should call the same abstractions that are provided in our lwip implementation.

Leo,

I got the TCP Client implementation to work. I used Wireshark as well which help me to debug the implementation in the network transactions.
I will post the codes here once it is in good shape.

Thanks for the help.
