OTA DFU for my own custom pcb

[Claudio]

I am new at this, I need to enable the OTA DFU mode on a nRF51822 QFAC chip on a pcb (the pcb has bluetooth). how can I program it? what do I need to configure? I am trying to use the nrf Toolbox on Android, after that I will try to develop my own app. so, any kind of help will be appreciated. Thanks

For getting started with how the bootloader (DFU) works, I would recommend you to read the DFU bootloader documentation.

As a start, I would also recommend you test our DFU example in the SDK.
