Hi,

Did you remember to flash the SoftDevice?

The hex(ble_app_beacon_pca10040_s132.hex) in the folder SDK_folder\examples\ble_peripheral\ble_app_beacon\hex have combined both the S132 SoftDevice and the Application code in Keil.

When you are building the code in Keil, you need to flash the S132 SoftDevice first. You can find the SoftDevice in the folder SDK_folder\components\softdevice\s132\hex
