OTA Functionality in central role and FOTA to its near by nRF51 peripherals

[Gotta]

Hi , Would you help me to find right material(App note, source code/project) to implement below case: My nRF51822 connected on beaglebone black(BBB) over UART this will acts as central for its near by BLE peripherals(also based nRF51x). So, now the BBB side BLE central device should be able to do FOTA or Firmware Update Over The Air to its near by BLE peripheral.

Hi

What we have is the Direct Firmware Upgrade (DFU) documentation here and DFU examples in the SDK. The documentation describes how DFU is achieved over a serial line (UART) or over BLE. If you want to receive new firmware over UART on your BBB and then do FOTA you will probably have to implement some code yourself that stores the new firmware before a FOTA process i initiated. Dependent on the size of your firmware, it might need to be temporarily stored on some sort of external memory.
