Hello Ethan,

This is built on the SDK\examples\connectivity\ble_connectivity example, but with some modifications. The actual source code (with modifications) is not open source, unfortunately, but I believe the example is is a good start if you want to know what's going on.

Best of luck,

Edvin

Edvin,

I'm looking for the actual SES or Keil project for the connectivity firmware that the BLE application in nRF Connect for Desktop uses so I can understand and reverse engineer the USB communication between the connected dev kit with the connectivity firmware and the BLE application.

Is this what you were referring to when you said "none of them are open source"? If I misunderstood, could you point me in the right direction to find what I'm looking for?

Thanks,
Ethan.

The ble_connectivity example is made for pc-ble-driver, a tool that allows you to write serialized applications for that run either on a computer or another MCU that uses the nRF, running the connectivity project, as a radio/BLE slave.

If you want to implement nrfutil from scrach, you can have a look at how it is implemented on GitHub:

https://github.com/NordicSemiconductor/pc-nrfutil

If you want to see what the DFU over BLE protocol looks like, you should check out the bootloader library documentation on infocenter. Partilcularly the message sequence chart may be useful, in addition to the BLE DFU description.

Best regards,

Edvin

Yes, that's what I try to do.

So what does the ble_connectivity example do? As mentioned I couldn't find anything about it in the Infocenter.

What I'm trying to do are OTA updates on IEEE 802.15.4 devices. To achieve this, the dongle needs to send a command over IEEE to the Beacons so it restarts into the bootloader. I could use two dongles, one with a IEEE Firmware and another that does the BLE update, but I would like to have this in just one. Can you please point me into a direction where I don't have to implement this from scratch.

Hello,

I believe you are trying to compile and program the connectivity firmware that is used in nrfutil and nRF Connect for Desktop. Is that correct?

If so, I must disappoint you. The FW that is used in nRF Connect for Desktop and nrfutil is not the same as the example from the SDK\examples\ble_connectivity. In fact, nrfutil and nRF Connect for Desktop doesn't use the same connectivity FW either, and unfortunately, none of them are open source.

Best regards,

Edvin
