softdevice not working good

[sajin]

i am using nrf52832 pca10040. i tried to run the ble blinky example from package installer. it compiles without any error, but when is load it to the DK it will not even advertise or enable Bluetooth.... When i opened the packages it shows a red mark in soft device portion... please help me to sort it off

That didn't work. the advertising and connected LEDs are turned on at same time with low brightness

Are you using SDK 12.1 ? If not, you can download it here.

Also make sure that you are using the correct Keil project:

SDK_INSTALL_FOLDER/examples/ble_peripheral/experimental_ble_app_blinky/pca10040/s132/arm5_no_packs
