Current consumption nRF51822

[Ziran]

Hi, I'm doing a project using the Evalution kit. I don't know why, but I can't go under 350 uA current comsumption in system on.

I did clear all pins,i did NRF_SPI0->POWER = 0 for SPIs TWIs and UART ,stopped the timer2 and the adc that I use for PWM and the battery service. I'm suspecting the 16MHZ clock but if I try to stop Timer 0 and 1 . My device is not advertising anymore.

Do you guys know how to solve this problem ?

I upped the slave lateny and the connection interval and managed to gain nearly 100uA but i have still 200 uA to go down .

Edit: Cutting SB8 and measuring with the 2 pins on the board solved the problem for me.

Hi,

I know this is an old thread but I am having a similar issue with my nRF51822. I am using a custom board though so I don't know how to apply your solution. Could you explain your logic so that I can apply it on my board?
