[Discuss-gnuradio] AUTOMATIC START AND STOP FILE RECORDING

Hi all Expert,

My project demands the recording of the same signal at different Stations. This recording will last for  3minutes.

It is critical for me to start the recording simultaneously and synchronized to more than 100ms accuracy between the stations.

The first option is to start the Flow graph simultaneously but I think it is best to rather automate the start of the FILE SINK for data writing whilst the flow graph is already running.   Manual brings uncertainties

I wish to ask our experts how I can achieve this FILE SINK automation in GNUradio.

Thank you for sharing your expertise
