2.6 Enable Accelerometer

Similar to the button notifications, the notifications for the accelerometer data can be enabled. This example only shows enable notifications for the x-axis.

First, enable the accelerometer by writing 01:00 to the characteristic handle 0x0035 in the Read/Write tab of BTool. To enable notifications for the xaxis, write 01:00 to the characteristic handle 0x003C. This enables the CC2541 Keyfob to send notifications as it is moved.
