Update but leaving it in here for reference, if someone else is wondering:
I just realised while scrolling back trough the postings that you are directly supplying 3.3v to the pins instead of the vbat pads on the back.
I guess this is the reasons and we cannot get lower when using the vbat pads…
Hello msfujino,
i am trying to get my Seeed Xiao NRF52840 non-mbed to use as little power as possible for a battery operated project which will use bluefruit ble as a client.
I used your sketch from 07.07.2023 as the basis to create a bare minimum blink sketch to get some baseline data.
However with i can only get down to 0.14 mA in the delay (measured with a rough resolving 0.00mA multimeter) - 0.41 with blue led blinking.
Did you undertake measures to disable the small charging led on the Seeed Xiao nrf52840?
Thanks a lot
