OTA DFU on customized board with nRF52832

I'm using PlatformIO and arduino framework yes. If needed I could learn all these tools.

I was trying with Zephyr and nRF SDK.

Also this link: https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/ug_nrf52_developing.html

But again, I have never used MCUboot...

I will check all these tools and see wich one suit me more

Are you perhaps using PlatformIO? I'm unfortunately not experienced in Arduino or PlatformIO at all, so I can't imagine your setup very well. I also can't help with DFU on those platforms.

I thought you moved to nRF5 SDK v15.0.0 though? Are you combining Arduino and the nRF5 SDK somehow?

Here are where you can download/setup the tools I mentioned.

nRF5 SDK v17.1.0: developer.nordicsemi.com/.../

Segger Embedded Studio v5.42a: www.segger.com/.../
Just pick v5.42a in the drop down menu.

nRF Connect SDK: https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/getting_started.html

Depends on your use case and how far you want to go with it, I can suggest either nRF5 SDK or the nRF Connect SDK.
Learning the nRF Connect SDK could be tougher, but it would be worth it if you want to learn the technology going forward.
We also provide a free course to get you used to nRF Connect SDK here: https://academy.nordicsemi.com/courses/nrf-connect-sdk-fundamentals/

But let me know your plan. If it is something very simple perhaps the nRF5 SDK would be just fine.

The problem is that my code is based in Arduino. I have never worked with Zephyr (learning this is an option).

I think I will have also issues working with segger (also that version is not available).

Any suggestions?

Hi Pablo,

Since the release of SDK v17.1.0, Segger Embedded Studio (SES) has got a few changes that caused the problems you have experienced.

If you are just starting out with your project, I would recommend using nRF5 SDK v17.1.0 with SES v5.42a, if not move to our active nRF Connect SDK.

What do you think about giving them a try first before we proceeded? Just last month I have tried updating firmware over BLE for both those options, and they work pretty well.

I'm using nRF5_SDK_15 and Segger 6.40 (I had some problems with version 17.1 and Segger).

I download the file "secure_bootloader_ble_s132_pca10040" of the DFU example into my board. I see my device called "Dfu Targ" in the app DFU from nordic and I upload the zip file generated with nrfutil.exe.

The problems are: the app says "firmware uploaded" but it's not uploaded correctly.

once I upload my .zip file I don't see my device anymore so I can't upload another file again.

I was following this video: https://www.youtube.com/watch?v=rf_kX0M11Pg&ab_channel=MonkeyCoder

Hello Pablo,

Are you using nRF5 SDK or nRF Connect SDK? The version you are on is also useful information.

Regards,
Maria
