ACTION_ABORT
Aborts the upload. The service does not need to be paused before. After sending BROADCAST_ACTION with extra EXTRA_ACTION set to this value the DFU bootloader will restore the old application (if there was already an application). Be aware, that uploading the Soft Device will erase the application in order to make space in the memory. In case there is no application, or the application has been removed, the DFU bootloader will be started and user may try to send the application again. The bootloader may advertise with the address incremented by 1 to prevent caching services.
