Central BLE DFU nRF52 Device

[Vojislav]

Hi,

What we would like to do is to store the firmware on one nRF52 MCU and do the DFU over BLE to the other nRF52 MCU. 
This means that the first nRF52 MCU  needs to connect to the second one, then communicate with the DFU characteristics to send it to the bootloader, and at the end send the firmware to the bootloader in fragments. 
I read through the Nordic DevZone and saw that people asked for this before, but it was not supported in the previous NRF5 SDKs. Has the situation changed? Is there a module or library that allows DFU firmware to be sent from the MCU, and not just received?

Also, do you think this is doable and see any major obstacles to it?

Best regards,
Vojislav.

Hi,

While not part of the SDK, we do have some example code for this as part of Getting started with Nordic's Secure DFU bootloader, a step by step guide. See the DFU Master code section, which links to code for an nRF side DFU Controller.

Terje

Hi tesc,

That is good news, will check it out, thanks!

In the meantime, I will open a new private issue so we can discuss this problem further.

Best regards,
Vojislav.
