Hi rushin

If you are using ble_app_beacon application in the nRF5 SDK, then major and minor values should be advertised as set by the APP_MAJOR_VALUE and APP_MINOR_VALUE constants in the main file. You can however make the application generate the major and minor values by defining the USE_UICR_FOR_MAJ_MIN_VALUES constant.

If you are using the beacon kit firmware 1.1.1, which flashes together with S110 7.1.0/7.3.0, then this thread contains some information on how to set the major and minor values in the advertising packet
