Central SMP Client and DFU upgrade from other MCU

Hello,

I apologize, but we don't have any references or official samples demonstrating OTA DFU from another MCU. Personally, I haven't worked with STM and PAN modules, so I can't provide insights on the implementation side. I regret not being able to offer more assistance on this matter. I would also suggest reaching out to the STM community, as they might have valuable insights or leads regarding this topic.

Kind regards,

Abhijith

Hi,

Thanks for your reply.

I checked out that too and it explicitly says: "This sample does not provide the means to program a device using DFU. It demonstrates the communication between SMP Client and SMP Server." Basically it's "blank" project.

I agree it could be a good starting point but as you said it's between two Nordics. I am looking for a way to have implementation on other MCU and I guess that I will need to port some part of the code etc. Is there information about the API available for (I am guessing) commands like eg. Init, Update, End? I am not familiar with nRF Connect sources for Andorid but would there be any useful information for easier porting to other MCU?

Thank you and have a nice day.

Hello,

Please take a look at the central_smp client sample. It demonstrates how to update a device that runs SMP_server. The way you implement this on your non-Nordic device depends on its operating system and specific setup. This sample is not official but can serve as a starting point. It shows how DFU (Device Firmware Update) can be implemented between two Nordic devices using SMP_client and SMP_server.
