Hi,

1) Have you done any modifciations to the example?

2) What IDE/Toolchain are you using ? SES, Keil, GCC, IAR?

3) Are you sure you are using the right project for the board you are using ? Use e.g. the pca10056 project if you are using the nRF52840-DK

Try doing a nrfjprog --recover, and then flash the application again.

If that does not work, try using SES version 5.42a

[Gopal Kumar]

Yes, it worked with SES v 6.30 with minor changes due to RTT Issue.

Thanks a lot!
