nRF51822 UART DFU Bootloader

There seems to be a fair amount of support and documentation for OTA DFU on the nRF51822, but I'm curious if there is any documentation on the wired UART alternative.

I'm building a large group of BLE-enabled smartphone powerbanks, the firmware on which needs to be updated in the field through a wired charging dock with a UART connection, so I'm hunting down information on the process on mbed and turning up a bit of a blank. Is there a source on this somewhere that I'm missing, and if not, can anyone describe the process to someone familiar with mbed but not familiar with the internals of the Nordic DFU bootloader?

Thanks in advance,

JBL
