Hi,

Thanks.

I have flashed softdevice S130 first and then application hex. But it didn't worked.

I had not added --reset switch to nrfjprog i.e. nrfjprog --program my_app.hex --sectorerase --reset.

Hopefully this could resolve my issue.

Thanks.

Hi,

It could be that you forgot to flash the SoftDevice. The SES projects in the SDK are configured to flash the SoftDevice for you. With Keil and command-line-tools you need to make sure that the SoftDevice is flashed yourself.

It could also be that you need to add the --reset switch to nrfjprog when you flash the application, for the CPU to start running after flashing. . e.g. nrfjprog –program my_app.hex –sectorerase –reset

Hi, Thank you.

The issue resolved when my application code build using keil and then programmed and the device advertising successfully.

Previously my code was in segger Embedded studio, and evrything works fine in debug mode but problem when I flash using command tools, program flash successfully but it not advertising.

But what exact issue don't find, it works fine when I flash the hex file which build on keil and if same code build on segger then it works only in debug mode, and not works when flash.

Thanks & regards,

Archana

Hi,

nRFGo studio is deprecated. Try using nRF Connect for Desktop and the progammer app instead. See this and this link.
