Raw (16- bit data) for Metawear sensors?

Hi 

Just had an idea:

Would it be possible to send/log the raw 16  bit data
for the sensors as opposed to the floats (4 bytes)? This will half the amount of data
being sent and logged. This mean that streaming could be twice as fast as well. It could then be scaled on the android app side to bring it into the correct units.


Cheers

    Sensor data is not modified on the firmware side.  The APIs convert the bytes into the relevant variable types.

    Hi Eric

    Thanks for the quick response. Just to clarify, how many bytes does each individual sensor reading take? 

    I'm guessing each takes four bytes, so perhaps the API could could be modified to send the data which comes straight from the sensor's data register. ie. 16 bits (2 bytes)? ie. do not convert it into a float. 

    Cheers

    The MetaWear already behaves as described in this thread.
