Recompilation of ble_app_hrs in nRF5_SDK_17.1.0 package does not work

[jinvers]

Hello,

I am using the Segger Embeddd Studio from the nRF Connect Desktop and the nRF52840-DK board.

I am working over the project into the "ses" directory for SoftDevice S140 version (..\nRF5_SDK_17.1.0_ddde560\examples\ble_peripheral\ble_app_hrs\pca10065\s140\ses\ble_app_hrs_pca10056_s140.emProject). Just as it is, I rebuid the project and it is done without any error or warning. But when I download it to the nRF52840-DK I cannot see the LED 1 flashing and I cannot bond the board.

If I reprogram the nRF52840-DK with the original hex file (ble_app_hrs_pca10056_s140.hex), then the board resets with the LED 1 flashing and prepared from bonding.

What should I consider to be able to get a compilation output to work on the nRF52840-DK board?

Thank you in advance.

Regards.

Hi Joel, 

Could you let me know how you downloaded the binary to the chip ? 
Note that you would need to flash the softdevice in addition to the application image. This is done automatically if you flash using Segger Embeded Studio. But if flash the application manually you need to flash the correspondent softdevice. 

The precompiled ble_app_hrs_pca10056_s140.hex has the softdevice included so you don't need to flash the softdevice. 

Please try to test with other applications as well.
