nRF52832 ble_dfu_buttonless_async_svci_init() failed with errCode=0x4

[snowuyl]

I change nRF52832 firmware to support DFU OTA. But ble_dfu_buttonless_async_svci_init() failed with errCode=0x4.

Hi, 

What SDK version are you using?

Do you program with the BLE Secure DFU Bootloader?

To run your application with the buttonless DFU, you would also flash the Bootloader settings page. 

Regards,
Amanda

Thanks for your reply! Sdk version 16.0.0. I am building ble secure dfu booter source code. Can I program it through j-link?

[Amanda Hsieh]

yes.
