Number of data points in a Bluetooth packet

Edwardsj · August 2016

Hi,

I log accelerometer data on the log module and download them every 2 minutes. I saw the power consumption of the board increased on the oscilloscope. I would like to know how many data points are encapsulated in each BLE packet in the downloading phase. So that I can estimate the power consumption during the download stage.

Thank you!

There are two 4 byte data chunks per packet.

Thank you, Eric. Can I also have the size of a raw accelerometer record? Is that 4 byte per record?

6 bytes per record

Do you squeeze 4 records in 3 packets or do you leave the remaining 2 bytes empty?

Thank you!
