Hi Vũ,

It should advertise or there must be something wrong. Please create a new case and describe with as much information as possible.
I also have a guide here that you may want to have a look: https://devzone.nordicsemi.com/nordic/nordic-blog/b/blog/posts/getting-started-with-nordics-secure-dfu-bootloader

Hi Hung,

How do you test the bootloader alone? I programmed the softdevice and the bootloader into my device, but I cannot find it when I scan on nRF Connect. Does that mean my bootloader is wrong?

Thanks

If you have 2 128bit UUIDs service, you need to increase NRF_SDH_BLE_VS_UUID_COUNT in sdk_config.h
If you change the services, you should erase bond information on the phone, try turn off and on Bluetooth, there is a chance that the attribute table is cached. Also make sure you set NRF_SDH_BLE_SERVICE_CHANGED = 1 in sdk_config.h
Please try to test first the bootloader alone, just to make sure DFU works (no bootloader setting or application flashing). Then please test with the default buttonless example, before you implement it on your application.
