Enabling low power mode in an NRF51822 MBED project, ported to uvision

[dextorama]

Hi, We designed an nrf51822 BLE application using the mbed kit and on-line tools.

Our target pcb has a 1.8V onboard supply. To minimise consumption i want to disable the DCDC and also access the other sleep functionalities of the nrf51822.

I have ported the MBED project code across to the uvision4 toolchain and have a segger to program with.

Anyone know the changes or code calls to access the nrf51822 DCDC and sleep registers in the MBED code?

Thanks!

Actually, I do not know how you do this in MBED code, but you could start coding in C and use the nRF51822 SDK. A blog on how to use the MBED kit with the nRF51822 SDK and Keil IDE is here.

A guide for lowering current consumption when using nRF51822 and the nRF51822 SDK is here.
Simple low power examples are here.
Also, some of the examples in the SDK are power optimized, e.g. the ble_app_hrs example

Anyway, by default, the DCDC should be disabled.
