ble send the firmware

[sanghan]

Hi there.

I Tested Example (secure_dfu_ble_s132_pca10040). Fine work.

but I could not find the example code to transfer the firmware.

I need the code to receive the firmware file via USB or Serial, etc... and send it to the target board with BLE.

Do you have any examples or notes to check?

In our latest SDK, v15.0.0, you'll find the Secure DFU Bootloader over Serial Link (UART/USB) example, the link will explain how to set up the example for testing. 

Unfortunately, we do not have any example in the SDK that relays the received firmware image to other nodes over BLE. 

However, our pc-nrfutil tool uses a nRF5 IC as a connectivity device, i.e. communicates over a serial interface with the PC acting as the PCs BLE hardware and can be  perform DFU.

Thanks for Reply.

This is what I think is the configuration.

PC > (Ethernet or Serial) > nRF_1(Sender) > (BLE) > nRF_2(Target)

Ok, if you go for 

PC > (Serial) > nRF_1(Sender) > (BLE) > nRF_2(Target) 

then you can use nrfutil without any modifications.
