VOXL Flight has 5 IMUs - 2 connected to Snapdragon and 3 connected to Flight Core. The board is basically 2 products in one. I want to collect and synchronize the data from VOXL and Flight Core side. What is the best way for doing that?
On the VOXL side I can use voxl-logger to collect camera and IMU information and on the Flight Core (PX4) there are ulogs containing all the needed information. 
If I understand correctly then VOXL side has timestamps in UNIX format, but (allegedly) the ulogs use microseconds since bootup? How do I synchoronize the voxl-logger and ulog data?
