Method for synchronization of timestamped data

A method of acquiring timestamped data and timing data by at least two devices wherein:

• Each device comprises an internal clock, an identifier, a a synchronization trigger, a memory, a wireless connection module and at least one sensor;
• The devices are tied so that each device knows the identifier of other tied devices;
• Each device acquires sensor data and, through its wireless connection module, continuously broadcasts its internal clock data and its identifier;
• For each device, when triggering by the synchronization trigger, said device acquires a timing data, said acquisition comprising:
• i. Scanning through its wireless connection module to receive internal clock data and identifier broadcasted by at least one of the other devices;
• and
• ii. Storing in its memory the timing data comprising its own internal clock data as well as the internal clock data and identifier received.
