Hi

Depending on the Beacon kit version you have, there are different bootloader versions preprogrammed to the Beacon kit, see the Beacon kit verison table on this thread. If you have Beacon kit version 1.1.0 or later, you have softdevice S110 7.1.0 and bootloader from nRF51 SDK 7.1.0 preprogrammed to the Beacon kit. This means that you can upload over the air via the bootloader any application based on nRF51 SDK 7, e.g. any BLE sample applications in SDK 7 that use S110 softdevice.

Unfortunately, you can not upgrade the softdevice over the air on the Beacon kit, you need to do that with a programmer/nRF51-DK and an adapter table, as described on this thread in the update from 27.11.2014

The bootloader from nRF51 SDK 7.1.0 requires an init file to be uploaded with the applicaiton. Here is a description on how to prepare such an init file
