@komal: Which project have you used? Have you used the ble_app_hrs_dfu.uvproj project ? The project should have the following file included : bootloader_util_arm.c, ble_dfu.c, dfu_app_handler.c

You can check if ble_dfu_init() is called.

bootloader.hex

ble_app_hrs_dfu.hex

tried to upload firmware with mcp v3.7 but with this version the first upload i.e firmware update from bootloader does not takes place. when i press dfu button for uploading it gives uploading firmware and stops at 0% only.

and when i use mcp v3.6 it gives error as:- No response received for ReadRequest on handle 0x000E. Disconnecting.. Lost connection to device. Reason: BTLE_LOCAL_HOST_TERMINATED_CONNECTION Service discovery aborted, connection terminated.
