RE: How to disable SPI to save power - nRF51822 on MBED

Hi Eric,

I am not familiar with the mBed API, and from my experience it does not support well for Low power.

It does not seem that there is any disable functions in the mBed SPI API, so maybe you could delete the SPI object to get the current down?

There is a spi_free() function that you could try, but I am not 100% sure how it's called since I could not find it in the API documentation for mbed.

I have two recommendations for you:

- You could use our SDK instead, and utilize the tips in the thread "How to minimize current consumption for BLE application on nRF51822".

- Check out the Zephyr project
