You can use a Device Firmware Update (DFU) to update the SoftDevice, bootloader, or application on an nRF5 SoC over-the-air (OTA).

See the following example if you use the ANT protocol and the ANT-FS transport:

• Experimental: ANT Bootloader/DFU

See the following example if you use BLE transport or serial (HCI/UART) transport:

• BLE & HCI/UART Bootloader/DFU
