MQX3.7 TCP socket timeout problem

javier1 — Tue, 19 Oct 2021 10:30:08 GMT

Hi to all,

I´m using MQX 3.7 in a custom board with Kinetis K60DN512 MCU, and I´m using this board with RTCS TCP in server mode (It´s connected with a PC asking data).

If PC is communicating with board works fine, but if I stop communicating 15 minutes, I can no longer communicate with the board. I have based on the example socket.zip (A socket proggraming demo for MQX / RTCS).

That is, when the 15-minute timeout operates, I don't know that a new communication is arriving. In document MQXRTCSUG.pdf, in 2.15.1 section (Changing inactivity timeouts) This timeout is 15 min. default.

How can I solve this problem?

Regards.

Hi Javier:

Sorry MQX 3.7 is a very old version. Now the latest version is MQX v5. Please refer to below link for more details.

https://www.nxp.com/design/software/embedded-software/mqx-software-solutions/mqx-v5-software-solutions:MQX-V5?tid=vanmqxv5

The latest free MQX version is V4.2.0 + patch 4.2.0.2.

Please refer to my attached change log for MQX RTOS, Lots of bug fixes in MQX 4.2.0, and it is more stable.

Regards

Daniel
