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

i am using nrf51 sdk. (1) i don't want APP_MAJOR_VALUE and APP_MINOR_VALUE as constant (2) i tried using defining the USE_UICR_FOR_MAJ_MIN_VALUES constant but in this method everytime i have to set major and minor using command window. so it is not use ful for me. (3) any other method available for 100 beacons?? different major minor number for 100 beacons using same firmware

Sorry, I think I misunderstood

To realize how to write the major and minor values from device address, look at the code snippet given on this thread. Perhaps you need to browse the beacon kit firmware 1.1.1 a little to fully realize what code is needed.

i can't find code there

beacon_data[BEACON_MANUF_DAT_MINOR_L_IDX] = (uint8_t)(NRF_FICR->DEVICEADDR[0] & 0xFFUL);
beacon_data[BEACON_MANUF_DAT_MINOR_H_IDX] = (uint8_t)((NRF_FICR->DEVICEADDR[0] >> 8) & 0xFFUL);
beacon_data[BEACON_MANUF_DAT_MAJOR_L_IDX] = (uint8_t)((NRF_FICR->DEVICEADDR[0] >> 16) & 0xFFUL);
beacon_data[BEACON_MANUF_DAT_MAJOR_H_IDX] = (uint8_t)((NRF_FICR->DEVICEADDR[0] >> 24) & 0xFFUL);

ok from where you write??
