In past, I spent considerable time on BLE OTA on nRF51 based custom board. Good news was that Nordic provides the bootloader (source code available) for the peripheral (which you may have to modify a bit to suit your needs) and central side android application (nRF Connect, source code NOT available). The BLE OTA design is explained in depth on Nordic's infocenter [1], perhaps it can be still useful to you.
