How to put nRF 51822 to sleep (Cost micron Amp level current)

[Alex]

Hi All,

I am new to BLE nRF 51822 development kit. It is mounted on nRF go Starter Kit. My question is how can I put a advertising 51822 chip to sleep? Also, when I turn on the board without loading anything to it, the K2 current measurement shows 260mV which leads to 2.6mA according to the current measurement description on nRF51822 Development kit user guide.

Shouldn't it be less than 1 micron Amp? Or it is not in sleep mode when it freshly starts?

Thanks~
