How to wake up nrf51 from sleep mode by a motion event

[Johannes Lorenz]

Hi,

on aliexpress you can buy a nRF 51 board with a LIS3DH digital output motion sensor:

Is there any example or source available, how to wake up the nRF 51 from sleep mode triggered by a motion event?

Yours Johannes

For any 3rd-party product, you should ask that 3rd party for specific support with their product.

As far as the nRF51 is concerned, its wakeup behaviour & capabilities are defined in its datasheet - so you will have to study that, and think how you can apply that with the facilities available on that board.

The LIS3DH is an ST product - you will have to study its datasheet for details of its functions & performance...

Hi

If you just need to wake up on a pin change you can use the GPIOTE driver in the SDK, as documented here.

Any example configuring buttons for wakeup should also be relevant, such as this one: Button example
