I have been doing some testing with the hibernation function on the DA14682 and the DA14681.
I have been using the ble-adv example as specified in the power measurement document. I have changed the sleep mode to "pm_mode_hibernation".
I am measuring a current of around 192uA when the device is in hibernate on a DA14681 basic dev kit.
On our production PCB with a DA14682 I am measuring a sleep current of about 200uA.
It appears to me that something isn't going to sleep fully, the flash maybe? Any ideas?
Thanks in advance.
