I don't need ble, only application+bootloader how to work ?

Hi Justin, 

could you elaborate on your use case? Do you plan on using a proprietary Radio protocol like ESB or Gazelle instead of BLE? Do you want to update the application using a serial interface like UART or USB? 

Best regards

Hi,

We have a serial/UART bootloader in the SDK. See this page.
