Problem: IAR compiled hex file does not work for ble_app_hrs

Environment used:

• IAR Embedded Workbench for ARM 7.80 Kickstart evaluation
• nRF52 DK

Observation:

1. IAR compiled hex is 83kB while the accompanying hex file for ble_app_hrs is 442kB
2. Compilation is successful.
3. Using the accompanying hex file, the android app shows value.
4. Unable to connect with the IAR compiled hex

Anyone knows how to solve this problem?

Hi, did you load the softdevice image (bluetooth stack) in addition to the application image as explained here? Note that the example .hex file is merged with the softdevice.
