DFU without USB BLE dongle

[abe]

Hi, I'using PCA100566 BLE DFU example and Nrf Connect desktop or NrfUtil to program/update.
The actual solution needs to use NRF USB Dongle for connection. It's possible to use directly the PC BLE interface to make this?
Like NrfToolbox on Android devices, that use the standard smartphone BLE interface.

Hi Abele, 

Unfortunately we don't have an example to do DFU from the PC's native BLE.

But I think it should be possible to implement one. I would suggest to have a look at the DFU library on mobile app, and follow the documentation of the bootloader library.

Hi Hung,
As update for my last request, my customer needs a DFU application under Linux. Have you any solution for this? Best if we can use a CLI interface...
As other solution, could we have the NRF Connect source code under android?
Many thanks for the support

Hi Abele, 

It's the same answer like on Windows PC. You can either use a Nordic's dongle or DK (or your custom board) to interface with the computer via UART and then use our ble_pc_driver (also works on Linux) to interface with it. The source code is available. 

Or you can access the BlueZ on Linux library directly but you need to write your own code to do that. 

We provide the source code for nRF Connect on PC, but not the one on Android as it's not made to be a reference design, but a tool. On Android we suggest to use the nRFToolbox as reference source.

Hi, the PC based application source files are available at what address?
