How to perform disconnected processing / logging?

alecz · October 2015

I'd like to program my MetaWear R series to process incoming sensor data on-board, identify events, and log them to a buffer to be read out by my iPhone.

Can this be done?

For example, I might want to:

1) collect accelerometer samples at 800Hz,

2) process that collected data on-board to detect impacts of a certain strength,

3) log those detected impacts with timestamps and magnitude values to memory, and

4) upload those values to the iPhone upon command.

I understand that there is tap detection built into the firmware, but I want more flexibility. Is there a way that I can write my own sensor data processing code to be executed on-board?

Yes, the firmware supports on-board data processing and offline logging. You can read about how to use these features on the iOS docs page, http://mbientlab.com/iosdocs/#events.
