Hi, 

Did you follow this tutorial: Add DFU support to your application to implement the BLE DFU in the application?

  Use nrf connect  try to update, the two update.bin send over , but it not wait update compelte and immediate return connect page.

What is the core do you update? App core or net core? Could you provide the log?

Regards,
Amanda

Hi Amanda,

  I'm sure implement the BLE DFU, when i used the nrf connect connected the device , it will show dfu icon .

  I try to update both core , when i update app core only it will be successful. it will immediate return connected page when transfered complete two core file.

  I use nrf connect version 4.26.0 , ncs version 2.0.0

Thanks,

wang

Hi, 

Do you set the config to support simultaneous multi image update this https://github.com/nrfconnect/sdk-mcuboot/blob/main/boot/zephyr/boards/thingy53_nrf5340_cpuapp.conf#L62?

Hope this example peripheral_lbs_dfu_update_net&app_core.7z can help.
