Our BLE app (based on ble_app_uart, example) on NRF52832 normally enters sleep by sd_power_system_off(). So this works as expected.
However, if we load the app by secure_bootloader_ble_s132_pca10040...
Hi,
We are using NRF 15.03 SDK and used NUS application for the project. We need to store some data into flash and we are using FDS example based code to do the same.
