I’m unclear on where this stands now.
I have a Xiao NRF54l15 module which is powered by a nordic power profiler II. It is supplying power through the 3V3 line on the Xiao.
The BLE advertising example seems to not work (initially it fails to build, fixing that,) it will build and flash but does not start the bluetooth advertising.
The ‘Ultra-low Power state’ example is my main concern at the moment. By applying the modifications mentioned above (updating the overlay to disable the regulators and pulling in the latest board files from the zephyr project) I am getting a power draw of ~450uA.
It is not possible to achieve the ~3uA low power mode when powering from the 3V3 rail or am I missing something from my setup?
