Create Telemetry Log

Hi,

I am writing my own GCS app, i wanted to be able to create “telemetry logs” from the app.
Unfortunately i was not able to find much about it, QGroundControl seems to save it as (timestamp + mavlink message) as raw bytes.

Could you help me find a way to create TLOGS ?

Ardupilot documentation about it just sends you to the Mission Planner section to see them…

Thank you
