On PC tool, it can show the logs from ETR in real time.

When one small packet send from STM to ETR, it can be stuck between STM and ETR. When the packet stuck happens, it will be flushed to ETR only when some other packets generated from STM source or CTI flush commands are sent. If the time is too long to wait for next packets coming, user will consider that issue happens with previous small packet. And user's requirement is that packet from STM can be flushed to ETR automatically instead of sending commands manually.

Is it appropriate to add a sysfs node for STM to generate the trigger packet periodically for such case ?

There's stm_heartbeat that will send a string via STM on a timer. It will come on its own channel, so your PC tool should be able to ignore it. Would that help?

Hi Alex,

It helps with my case. How to implement it ?

Thanks Jinlong Mao
