where does MMR get the time info?
I have 2 MMR sensors and I grouped them in the MetaBase application to start data (acc & gyro) logging. After downloading the log files, I see data entry like the following:
epoc (ms),timestamp (+0800),elapsed (s),x-axis (g),y-axis (g),z-axis (g)
I want to know from where the sensor gets the time information. Does it have an internal clock or if it retrieves from the smart phone when it communicates with the phone through MetaBase app?
