Hello,
We have a application with soft device on nrf52832 with SDK 15.3 with 60 uA power consumption. It works as it seems for now.
We wanted to add DFU buttonless feature to our product then its works fine only power consumption rises up to 1 mA at idle state.
There is 2 big difference in application these as you might expect, NRF DFU Buttonless Service init and calling this fonction at the begining of main
ble_dfu_buttonless_async_svci_init();
Best regards.
