Hi,
I am using Zephyr to do some action in a main loop and ksleep for 30 seconds. While in ksleep(), I can see that the consumption is 20ua. The board is a very small simple board which only has a button and four LEDs on it. The LED's are off in ksleep. Things that I have tried:
1) Turned off UART
2) CONFIG_SERIAL = n
3) Turned off debug/logging and disconnected debug tools (JLINK) and power cycled
4) The code advertises in BLE before the ksleep, but i make sure to shut down advertising before sleeping by running bt_le_adv_stop();
What could be causing it?
