Dear,
I got nRF5_SDK_15.3.0_59ac345 package but I couldn't find "Heart Rate Demo for nRF52 DK" source code there.
Actually, I found the HEX file of " "Heart Rate Demo for nRF52 DK" and it worked well with Android nRF App. So, I like to use this source code to leverage.
My envrionment is
Board : PCA10056
SDK : nRF5_SDK_15.3.0_59ac345
Would you please let me know the location I can download?
Regards,
Jae
