TM4C1290NCPDT: Energia MQTT/Ethernet Connection issue

Part Number: TM4C1290NCPDT
Other Parts Discussed in Thread: ENERGIA

Hello,

I had posted this issue on Energia forum also, but no response from there? Hope to get some help here.

I have built an application which is based on the PubSubClient and Ethernet library.Tm4c129 is expected to publish some data and subscribe to some topic through MQTT. It works perfectly well when there is only one TM4C129 is connected to the LAN. If I try to connect/dump code on another TM4C129 on the other LAN the earlier connection would disconnect or the later one. I am not clear about why this happening? Did anyone come across this kind of issue?

Thanks.

Hi,
MQTT is not supported on TM4C129 but someone has demonstrated to work in this thread. e2e.ti.com/.../2064820. Hopefully other community members maybe able to provide additional comments.

Hi Charles,

Thanks for your reply!

I have implemented MQTT protocol on TM4C129 in CCS, but I was only able in publishing some data on MQTT, and was unable to subscribe to some topics in CCS. So I switched to Energia. The application I've built is in Energia now. The above issue I'm facing is related to Energia.

I expect a helpful reply from TI people on this.
Thanks.
