What file did you flash to your device and what tool did you use to flash it?

Hi Einarh,

I am trying to get the server side working on this page: https://github.com/simon-iversen/ncs_samples/tree/master/central_smp_client_dfu while the client side is fine, and showing that it's scanning after starting up. The server side is showing me this:

While building or flashing it, I have not received and error message so I assumed that everything was fine, but now it' telling me it failed reading image header.

Thanks,

It's hard to say without more information and context.

What page are you following instructions on?

What exactly are you trying to achieve at this point?

What things did you test that worked correctly before you encountered this unexpected behavior?

What NCS version are you using at this point?

Thanks Einarh,

I tried it on both Windows and Linux machines. While mcumgr echo command (

sudo mcumgr --conntype ble --connstring ctlr_name=hci0,peer_name='Zephyr' echo hello) from

https://developer.nordicsemi.com/nRF_Connect_SDK/doc/1.7.1/zephyr/samples/subsys/mgmt/mcumgr/smp_svr/README.html on Windows replied with a message saying Windows does not support mcumgr. (As expected) Linux couldn't get a response from the development board and said it could not get a response in 10s. I followed every step of the instructions on that page. Installed everything asked. Everything seemed fine up to that point. I tested with the Nrf connect phone app, and was not able to pick up the dev board from the scan. Can you think of any reason why that would be? Is there any test I can do to sort that out? Or could you share a binary/hex file that works so that I can at least check my set up?

Thanks and Regards,

Karen

This doesn't sound like a good idea, and I would expect errors like the ones you are getting.

Instead I would recommend looking at how to generate keys in the documentation you linked:

Hi Einar,

I've been trying to repeat the example you have suggested. I got stuck in trying to build the server side: (4) "Build and program the sample \zephyr\samples\subsys\mgmt\mcumgr\smp_svr to nRF52840DK_server with the Kconfig fragment \smp_svr\overlay-bt.conf applied"

According to the readme file, I'm supposed to sign the sample image as such:
west sign -t imgtool -- --key bootloader/mcuboot/root-rsa-2048.pem

But I don't have root-rsa-2048.pem, so I tried downloading the source files and compile it following the instructions here:
github.com/.../readme-zephyr.md

But I failed at the ninja command, with the following error:

I had a lot of duplicated definitions, but they are all defined in generated files, so I can't just remove them.
Do you know how I can solve this issue?

Is there any reason you're trying to install this manually?

I would recommend installing NCS through the Toolchain Manager in nRF Connect for Desktop.

Hi Einarh,

Thanks for your reply, I was building for the nRF52840 because I was trying to follow the instruction here: https://github.com/simon-iversen/ncs_samples/tree/master/central_smp_client_dfu and I was using a development kid as per the example. I did end up being able to program the client part after a few tries.

Unfortunately I was still having troubling recreating the server side.

"Build and program the sample \zephyr\samples\subsys\mgmt\mcumgr\smp_svr to nRF52840DK_server with the Kconfig fragment \smp_svr\overlay-bt.conf applied"

I kept trying to install and use "west" but couldn't because of this error: File "C:\Python311\Lib\re\_parser.py", line 841, in _parse
raise source.error('global flags not at the start '
re.error: global flags not at the start of the expression at position 9"
while installing the requirements described in this page https://docs.zephyrproject.org/3.2.0/develop/getting_started/index.html (It's also described in this nordic page (https://developer.nordicsemi.com/nRF_Connect_SDK/doc/1.7.0/nrf/gs_installing.html#install-additional-python-dependencies):
pip install -r %HOMEPATH%\zephyrproject\zephyr\scripts\requirements.txt
This happened regardless of whether I was using a virtual environment.

Thanks,

By log output I meant the log in the programmer that gave you the error.

But I don't think that will be necessary as I see you are building for the nRF52840 DK, while you will probably want to build for the nRF52840 dongle instead.

The build was generated by opening the central_smp_client_dfu folder. At the NRF for VS code page, I selected nRF connect 2.0.0 as suggested by the instruction. And I clicked pristine build under "ACTIONS".

There is nothing at the output terminal, one warning that says "__ASSERT() statements are globally ENABLED". But a bin file is generated none the less as zephyr.bin. There is another one called isrList.bin which I didn't use.

[quote user="karenl"]Unfortunately, I can't say the same about the generated zephyr.bin file, I could not actually download the generated bin file the error came back as "Unspecified error -1"[/quote]

How exactly do you generate it and please share the full log output.

RE: How to create customized software to program boards via bluetooth on nRF Connect

karenl — Wed, 14 Dec 2022 04:32:38 GMT

Hi Einarh,

Our DK board has finally arrived and I can confirm that at very least, I could follow the instruction and download the provided bin file to the board, and that it can actually connect to the computer afterwards. Unfortunately, I can't say the same about the generated zephyr.bin file, I could not actually download the generated bin file the error came back as "Unspecified error -1". And the two bin files are not identical. It is very important that the generated file operate the same way as the provided bin file. Otherwise, we can't proof that the source code works.

The colors indicate what each memory section contains:

1) Are you sure you've selected the right device in the programmer?

2) Are you sure you've added the right file?

3) Could you please share the output of the log output?

Hi, Einar,

I have been using this program to program my device. But I usually see memory map with green, blue and orange regions, like the one on the right, not just the one orange region.

RE: How to create customized software to program boards via bluetooth on nRF Connect

Einarh — Tue, 13 Dec 2022 09:20:00 GMT

Have you done every step described here?

https://infocenter.nordicsemi.com/index.jsp?topic=%2Fug_nc_programmer%2FUG%2Fnrf_connect_programmer%2Fncp_programming_dongle.html

If you're still having issues, could you share a screenshot of the programmer application?

Hi Einar,

Thanks for this, I've just been able to compile this, but when I try to test it on the dongle by programming it via the nrf Connect programmer, I could see the data appeared as orange at the bottom of the memory map, but the "write" icon was not activated. Do you know why that is?

Also, is there a way of programming the dongle without using nrfConnect Programmer?

Thanks,

This is the error that I'm getting just by opening the folder pc-ble-driver. I didn't show it last time because I thought it's a dependency problem I'll have to solve.

The ble connectivity firmware that I used, I compiled it from this folder from the SDK I downloaded: nRF5_SDK_17.1.0_ddde560\examples\connectivity\ble_connectivity\pca10056\ser_s140_usb_hci . According to Hung's answer, the connectivity firmware is very close to the firmware that's used to reprogram the dongle, with just some extra patches, what are those extra patches? If I do use the Visual studio to compile the code, which project do i use, there are at least 4 main.c files.

Thanks for your help.

[quote user="karenl"]I was not able to successfully build or even open the codes in Visual Studio 2022 without errors[/quote]

You would have to share these errors for me to be able to help with that.

[quote user="karenl"]Is there a version that works with Keil?[/quote]

Keil is not supported.

[quote user="karenl"]I tried using the ble connectivity code[/quote]

I would need more details on how you tried to use it to understand the context here.

[quote user="karenl"]asked to reprogram the dongle firmware[/quote]

I assume it is nRF Connect for Desktop you are using that is asking you to reprogram the dongle?

The whole point is that if you want to not reprogram your dongle you will have to write your own program that does the same things that nRF Connect for Desktop does in addition to anything else you want your program to do.

[quote user="karenl"]I basically just want the source code of the file that gets downloaded to the dongle after the prompt "Device must be programmed, do you want to proceed?"[/quote]

Then you should look at Hung's answer in the thread you linked.

I tried following the instructions, I was not able to successfully build or even open the codes in Visual Studio 2022 without errors. Is there a version that works with Keil? I tried using the ble connectivity code, I got this message from the log: "Received status with code 0 PKT_SEND_MAX_RETRIES_REACHED, message: 'No response from device. Tried to send packet 6 times.'" and when I pressed the reset button, I would be able to connect, but still be asked to reprogram the dongle firmware, which example can I use as a reference to build my code on such that I won't need to reprogram the dongle? I basically just want the source code of the file that gets downloaded to the dongle after the prompt "Device must be programmed, do you want to proceed?"

Hi Einar,

I've that quote from this post: Example for Performing OTA DFU from NRF52840 Dongle to NRF52 peripheral ?

What I'd like to do is to use the dongle to transfer data via Bluetooth from my peripheral device to the computer (meaning I have my customized software on the dongle) while also using it to upgrade my firmware on the peripheral device when it needs upgrading. Because currently if I need to use the dongle to upgrade the firmware on the peripheral device, I need to reprogram the dongle with a special firmware from Nordic, and then put my own firmware back in afterwards. I would like to use just one firmware to do both. If that's possible.

Thanks,
