Hi,

First of all the TM4C123 doesn't have a built-in Ethernet module. If the GSM900A has the TCP/IP stack built in then you should be able talk with the GSM900A through serial interface. For serial interface, you can find examples,

C:\ti\TivaWare_C_Series-2.2.0.295\examples\boards\ek-tm4c123gxl\uart_echo // this is a complete CCS project for uart demostration

C:\ti\TivaWare_C_Series-2.2.0.295\examples\peripherals\uart // there are two example c files for uart

This article should be also helpful.

Hi,

Who makes this GSM900A? I recommend you reach out to the vendor of this module for support on MQTT. I'm not even sure if you are talking about SIM900A or GSM900A as I can't even find anything related GSM900A by doing Google search. If your question is about using the MCU on how to use the UART module, please come back to us. If the question is about an external component (.e.g. GSM900A) please reach out to the respective vendor for support as we have no knowledge about it.

I am able to send text msg using tm4c and SIM900A by using AT commands.

Also I have done MQTT using TM4C and SIM900A in energia, but I have only problem in CCS(code composer studio).

In energia there are MQTT labraries but not available in CCS.

Hi,

You can import the Energia into CCS. In CCS->File->Import you will find the below import selection.

Hello,

What exact version of CCS are you using? And which version of Energia? Based on the path, it looks like version 15? If so, that is a pretty old version and I would recommend using a more recent version.

Thanks
