Re: Minimising power consumption on the nRF52

Just done some more testing. If you build the bootloader without any additional syscfg files, the default BSP syscfg will take effect. For the nRF52DK board, this automatically turns on TIMER_0 (which subsequently enables the HFXO) and enables the UART (each of which consumes significant power,

Minimising power consumption on the nRF52

Hello all, I've been experimenting with mynewt and the nRF52DK board trying to create a low power application. I've been working off the hello_world app since it is simple. By default, when running the hello_world app, the nRF52 consumes around 1.5mA. Disabling the UART (by settings UART_0: 0 and
