The example HEX file is invalid.

I try to flash or mergehex ble_app_blinky_nrf52840_mdk_s140.hex or ble_app_hrs_nrf52840_mdk_s140.hex, it's failed.

But I can flash the s140_nrf52_7.0.1_softdevice.hex in same way.

@zorange-CN The ble_app_blinky_nrf52840_mdk_s140.hex or any hex files with _s140 suffix contains the s140 softdevice. So there is no need to merge another softdevice again. Just flash it and it will run.
