Hi,

For instructions on how to compile/debug Android source code you should visit the Androids web site, as we specialize in Nordic products.

Hi Amanda,

Please share how to debug the Android code(in Java) to understand the flow for DFU controller to write to DFU target.

Please help as soon as possible.

Thanks & Regards,

Aswati

Hi,

Unfortunately, we do not have any official C/C++ implementation of the DFU controller. You may refer to the BLE transport documentation if you want to implement your own. Here are the message sequence charts: https://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v15.3.0/lib_dfu_transport_ble.html?cp=5_1_3_5_2_2_3#lib_dfu_transport_msc

Hi,

Nordic does not provide any DFU Controller implementation for the nRF, and there are no immediate plans to do so. However, we provide a few other DFU controller implementations that you can use as a reference:

You can also refer to the DFU protocol documentation.
