Low power UART library

[sboudaud]

Hello,

I wanted to ask which uart library we have to use in SDK16 and which configuration to have a LOW POWER UART

We are in development phase on the devkit PCA10040 and our future device will have nRF52810 and SDK16

Thanks by advance.

Hi Stephane, 

I think that the nRF5 SDK v16.0.0: Libuarte - advanced UARTE driver is the best fit for this. Quote from the documentation: 

nrf_libuarte_drv can be configured with hardware events that will start and stop the receiver. This option can be used, for example, to build a low power UART protocol with request and response pins that will enable the receiver only during a transfer. All hardware tasks and events are connected with PPI, which allows autonomous operation that does not depend on the interrupt handling time.

Best regards

Bjørn
