nrf52840 sleep mode system off impossible

[Miguelio]

Hello i have a keyboard with nrf52840 with ZMK firmware, BLE, adc, gpios, i2c0, usbd, DCDC and CONFIG_CLOCK_CONTROL_NRF_K32SRC_RC

When it is connected with the computer the power is 1.24mA +/-... is "ok"... but when it is in deep sleep the power is 1mA and don't have idea of the problem

any help? thanks

Try setting CONFIG_SERIAL=n in the prj.conf of the main application (and in the as well child images if you got any).

Hello thanks for the response, 

I had output pins set to pull down

and that made me spend a lot of energy
