Current measurements on nrf52840 pdk with PPK

ble_app_gls_pca10056_s140.hex

Hi, I am new in this field and i am trying to do current measurement on the nrf52840 PDK using PPK, in sleep mode(sd_power_system_off) i get average 40 micro amp which suppose to be 0,6! while in advertising mode the average is 700 micro amp. I followed this to prepare the PDK for current measurement and this for PPK configration. am i doing it wrong? I am using ble_app_gls example with soft device s140

Hi Nahro. Just ran the ble_app_gls application on my nrf52840 pdk. Got an average of 40 uA when sleeping and 1.3 mA when advertising. I have not made any modifications to the code yet. Let me get back to you soon.

hi Bjørn, I tested (ble_app_queued_writes and ble_app_hrs) the average is 40uA in sleep mode.

Hi Bjørn, did you figured out the problem?

Which nrf52840 pdk version do you have? What does it say under PCA 10056 on the MCU of your PDK? Is it <=0.9.3 on the second line & then 2017.39 for example on the third line? Have you taken a look at this case?
