experimental_lpn can't use LDO?

[john.liu]

I use nrf5_SDK_for_Mesh_v3.2.0_src\examples\experimental_lpn and board PCA10040.

When I close main.c ERROR_CHECK(sd_power_dcdc_mode_set(NRF_POWER_DCDC_ENABLE)), nRF Mesh app can't find it.

Hi John, 

It worked here for me when commented out the line. Could you double check pressing a reset after you program the board ? 
Also please try to test with Mesh SDK v4.0, to see if the issue remains.
