Recording from several devices at same times lead to time values of zero in .dat files. #21

Hi all,

I have two STWIN.boxes connected by USB to a Raspberry and I'd like to record vibration (iis3dwb_acc) and sound (imp23absu_mic) data with these two STWIN.boxes simultaneously. Data logging using SensorAcquisitionThread behaves correctly, but when data from the imp23absu_mic.dat file is read in later using get_dataframe, the sound data have a time value only up to few seconds, after which this value remains at zero.

Recording from only one STWIN.boxe over USB works as expected.

fp-sns-datalog2 version used: 2.2.0

Hello @Ferag-AG I'll review and debug your files, then I'll come back soon. I'm happy to see an example of a custom application built upon top of our SDK. The multiuse case has never been tested internally or natively supported by our examples. Let see if I can help you debug your application.

Best regards,
