On smartphone with BLE, download "nRF Master Control Panel (BLE)" app:
nRF Master Control Panel is a powerful generic tool that allows you to scan, advertise and explore your Bluetooth Smart (BLE) devices and communicate with them. nRF MCP supports number of Bluetooth SIG adopted profiles including Device Firmware Update profile (DFU) from Nordic Semiconductors.
