IoT Modules Smart Module

I have sc600t for android 10,

  1. echo mem > /sys/power/state on debug uart and removed usb and other connection and enabled airoplan mode.

echo mem > /sys/power/state whenever we are sending device in suspend state.
device is automatically wake up.
even we find all wakeup source from /sys file using find ./ -name wakeup. and disabled it. still device is auto wakeuping.

Hi,
Can you help confirm whether you module has pmi or not.
You can also capture log after inputing these commands:
echo 8 > /proc/sys/kernel/printk
echo 1 > /sys/module/msm_show_resume_irq/parameters/debug_mask
echo 0 > /sys/module/qpnp_rtc/parameters/poweron_alarm
