DFU SMP Client

[Christoffer Brask]

Hi,

Related to this topic BLE DFU, MCU to MCU (Zephyr), GATT DFU SMP Service Clinet

I would like to know if anyone has any luck in making a SMP client for DFU updates between two nRF52?

I cannot find proper documentation on how this should be implemented, is the source code of Nordic's Device Manage app or the mcumgr CLI the best starting point? 

I cannot find any SMP documentation besides top of the header file which basically says nothing.

As it is right now, my backup plan is just to use the dfu target library and make my own transfer protocol with a characteristic to do the DFU update but surely there must be a more official way to do DFU updates among MCUs.

Hi Christoffer,

Thank you for the request. Lack of documentation has been reported. I will get back to you when I have more information.

Best regards,

Hi Christoffer

Håkon is currently unavailable, and I will help out with your case in the mean time. 

Did you get any further with this?

Unfortunately there are no news to share from our side yet, but I have asked the developers if they can provide an update. 

Best regards
Torbjørn

I decided to move forward with the dfu target library making my own transfer characteristic
