dear 

  recently ,i encounter a question about the 3100 current consume .

i use release_mra2_10_1_nhs3100 SDK packet , i use the default NHS3100 Temperature Logger project and just remove the define of BOARD_ENABLE_WAKEUP  and  set the PIO0.0 PIN pull up ,because i do not use the wake function .

if i connect the wake up pin to the VCC, i get the current consume is 10μA both in power off mode and dpd mode ;

but if i connect the wake up pin to the GND, i get the current consume is 10μA in power off mode ,and  get the current consume is 50μA

in dpd mode .

i want to know is this correct result when correct the wake up pin to gnd?why this occurs ?

what can i do to decrease the current consume without change the pcba design ? i
