Hi,

The failure happens because Master Control Panel is not yet able to handle the swap from application to bootloader/DFU mode.

The HRS application does not contain the full DFU implementation but only the service. Writing 'Start DFU' to the Control Point makes the application jump into Bootloader/DFU mode and from there the MCP can be used to perform the update.

Jumping from app to bootloader/DFU is a manual step that can be done in MCP.

Just follow the procedure in the attached screen shots. And once this is done, then do a new Service discovery and perform your update using DFU from Master Control Panel.

note Make sure that the Heart Rate application your are using is the ble_app_hrs_dfu from the project with same name. The normal Heart Rate project does not contain the needed DFU service.
