Device not connecting after DFU OTA

Hi,

I am running the BLE DFU example. I am able to perform the DFU OTA implementation successfully. The problem I am facing is that, once the application has been updated successfully, the device gets disconnected and starts advertising with new name. But when I am trying to connect to it, its disconnecting again and again.

I am using the hrm zip file for updating. The device after updating advertises as Nordic_HRM.But I am not able to connect to it.

  • Could you resolve my one more doubt. Which is the bootloader file that I have to flash in the bootloader region? Is it the hex file given in the bootloader example??

    If so, does the hex file code contains only bootloader part or does it also have the application part in it
