Hi Yan:

as we talked this is a sta listen interval boot up current .  This is a 80211 rule , we can't avoid this kind act .

please decrease the power and find the pcb placement or layout to see where has a EMI to the sensor module. thanks.

Hi  Yan:

      The current is from Vbat pin ?   do you try to change another fw to have a try .

We usually have a current bursting up according DTIM setting, but not 2 minutes .

and the burst is very short, not like the wave you measured.
