[micele]

I use nrf52832 qfaa b017351o ,some ic can run sdk11 dfu demo but some ic can't. Demo  location  .\nRF5_SDK_11.0.0_89a8197\examples\dfu\bootloader\pca10040\dual_bank_ble_s132\arm5_no_packs.

 All ic can run ble_app_uart demo.

Is this on your board or the development kit?

Use my ic on development kit.

If you're using the nRF52832-DK, all examples are tested with this kit.
