Hi,

I'm glad to hear you found the culprit. But qas UART2 previously enabled in your board overlay? It is disabled by default in the nrf9160dk board files so I'm not sure why it was enabled in the first place.

Best regards,

Vidar

When I turned on uart2, the power consumption of 9160 increased to around 700ua, although I confirmed that statement of pm_device_action_run(uart_ble, PM_DEVICE_ACTION_SUSPEND) had been executed, it causes uart2 to enter low power consumption, and from the log information, it can be seen that the instruction execution is correct and the returned status is also correct.

Hi,

I found that this issue seems to be caused by uart2, because after I banned uart2, the power consumption of 9160 decreased to only a few 40 uas. What I want to know is whether uart2 is occupied by other applications? Causing my application to even set it to PM_ DIVICE_ ACTION_ SUSPEND is no longer working? Additionally, I have re uploaded my conf and overlay files.

Hello,

It looks like something happened with attachments, I'm not able to download them. Can you please try to re-upload them?

Thanks,
