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.

Thanks Bjorn for the quick reply

that's strange. Libuarte example reaches 9mA average. How is it going to be used as low power?

[bjorn-spockeli]

9mA is very high. Based on the nRF52832 Product Specification it would seem that the CPU is running, typically ~8mA. The additional 1mA is probably the HFCLK and UART peripheral compounded. So it could sound like there is something that prevents the sample from going to sleep, i.e. WFE or WFI. I suggest you open a new ticket with details on your setup and serial traces if possible.
