Thanks for the suggestion. Fllowing the above operations, I found the problem in the code, and resolved it.

It's a bit late to reply, thank you very much.

Best wishes to you.

You could try to add the hardfault library to your application, and see if you get an any hardfault information in the handler.

Add these to your projects:

$(SDK_ROOT)/components/libraries/hardfault/hardfault_implementation.c
$(SDK_ROOT)/components/libraries/hardfault/nrf52/handler/hardfault_handler_gcc.c (variant here depends on your toolchain)

And set HARDFAULT_HANDLER_ENABLED to 1 in sdk_config.h, and add DEBUG_NRF in your preprocessor definitions

1) i am using nRF52 SDK v17.0.2, and i'm so sorry that the version number of the softDevice was written in the article.

2) After I sent the command through the serial port tool, there was no ack response and no log information was output in J-Link RTT Viewer. And only after re-downloading the program can it be used normally.

Hi!

1) Are you using nRF5 SDK v17.1.0?

How do you detect the crash? What happens? Does the device reset, become unresponsive, etc ?
