Hi.

I readed tutorial but I have questions.

I can't start ble_app_buttonless_dfu. I get erroor "NRF_BREAKPOINT_COND".

What do I do wrong?

[bjorn-spockeli]

This means that one of the APP_ERROR_CHECK checks are asserting. Take a look at the call stack and try to see which function that generated the assert.

I look call stack. 

I got error when function call APP_ERROR_CHECK(err_code);.

YEs, so its ble_dfu_buttonless_async_svci_init that returns a non-zero error code. This is usually due to the bootloader not being flashed to the nRF52. Compile the bootloader example and flash it to the nRF52 in addition to the buttonless dfu example and the S132 softDevice. See the documentation on the bootloader example.
