I am in the nrf52-DK board, download S332 SoftDevice v2.0.0 and SDK12.3 in the experimental_ant_bootloader routine, can not enter the DFU mode. How can I operate to enter the Bluetooth DFU state？

Hello, nordic team； I want to create a DFU for the ANR + BLE device in the nRF5_SDK_12.3.0_d7731ad \ examples \ dfu \ experimental_ant_bootloader routine.But I use this routine burned into and can not run up?I did not see the DFU's broadcast messages？I now only burn the protocol stack and experimental_ant_bootloader。 I now only burn the protocol stack is: ANT_s332_nrf52_2.0.0.hex； I am using nrf52832 nrf52-dk board； I would like to only burn the protocol stack and DFU go, DFU can update the application.How can i do this to achieve this function? Thank you, hope to get your help!

The ANT Bootloader only communicates using the ANT protocol and will therefore not show up if you're scanning for BLE devices.

The typical use-case for peripherals that support BLE and ANT is that BLE is used to connect the peripheral to a smartphone and provide firmware updates, while ANT is used to connect to ANT-only peripherals like heart rate sensors or cycling computers and this data is then relayed through the BLE link.

My suggestion would therefore be to use the BLE bootloader to provide DFU capabilities to your product, which then updates the combined BLE and ANT application.

Best regards
