Unable to add system off sleep mode in zephyr

[SM_]

Hi,

I am new to zephyr. 

I have tested Ibeacon and System off example individually on nrf52840 PDK board.

I am trying to add system off (Deep Sleep) mode in the zephyr Ibeacon example. 

for that simply I have added the header files of system off example in the Ibeacon example and the below two lines

pm_state_force(0u, &(struct pm_state_info){PM_STATE_SOFT_OFF, 0, 0});

k_sleep(K_SECONDS(SLEEP_S));

in main of Ibeacon example. 

such that after Ibeacon function execution the system off is executed and remains in it.

but I am not getting the expected results as I check the power consumption of the board using the PPK 1 board, it shows 400 - 600uA.

Please help me to resolve this issue or please share any link of sample example related to this.

Thank you for reply,

I've done all of them.

I mounted just BLE module with  capacitors only.

I got the same result,1 mA.

By disconnecting JTAG it reduced 10-20 uA!

Is it a possibility of hardware problem?Or the custom board definition which I defined in VScode for zephyr?

Hi MTR, 

Please create  a new ticket for your case. 
We are not so sure what could be the problem. Have you tried to test on multiple module or only one module ? 
I assume what you meant by "reduced 10-20uA" is that it's still close to 1mA and just dropped 10-20uA from that , correct ? 
Please reply in the new case and not continue in this.
