Hi,

I changed the device's USB cable and COM port and it works,

Thank you for your suggestions, it's very helpful.

Best regards,

Hello,

That is great news. Did you find out what the problems was?

It should work, but be aware that the Mesh DFU has a very low throughput. I haven't tested with the v2.0.1, but I tested with v1.0.1 some time ago. I just modified the DFU example to turn on different LEDs, and uploaded that project via DFU. So it should work with larger projects as well (I see no reason why it shouldn't work in SDK_v2.0.1).

But as I mentioned, the throughput in Mesh is quite low, so the DFU process took about an hour. The advantage with Mesh DFU is that the DFU process runs in the background of the application, so for an in field DFU, the customer may start the update, but they can use the device as normal until the update is done. This will trigger a reset, and the device will run the new application. It is not that easy to see in the DFU example, because it does nothing else. But if you add a bootloader to the blinky example, or the blinky functionality to the DFU example, or the light switch example, you can see that the device is operative during the DFU process.

Mesh DFU is intended for in field updates. If you just want to tweak parameters or something, I suggest that you program the chip normally, and just run a DFU test in the end before shipping out the firmware.

Best regards,

Edvin

Update:

It works now finally and my two DK start blinking, now I want to use light switch server example instead of blinky application, is that possible? I believe DFU over mesh doesn't support big application like light switch demo, is that correct?

Hi,

I ran the command and here what it it prints

C:\Users\Arij\Desktop\mesh\nrf5_SDK_for_Mesh_v2.0.0_src\nrf5_SDK_for_Mesh_v2.0.0_src\tools\dfu>python bootloader_verify.py 682501995 COM10
Device family:                  NRF52
Reading UICR..                  OK.
Reading Device page..           OK.
Resetting device..

I put the serial number of my serial device (host) and its COM port,

Now I tried with the other device and I put its serial number and COM port, and here what it shows

C:\Users\Arij\Desktop\mesh\nrf5_SDK_for_Mesh_v2.0.0_src\nrf5_SDK_for_Mesh_v2.0.0_src\tools\dfu>python bootloader_verify.py 682609257 COM15

Bootloader verification OK.

Run.

So I think here the bootloader worked with my other device that is supposed to be the target and not with host device, they are both connected to pc with USB cables. I'm still understanding the process of DFU over mesh, Do I have to restart all over again the dfu start guide and see if it works with my other device?

Thank you,

Hello,

Can you try to run the script in the path:

mesh_v2.0.1\tools\dfu\bootloader_verify.py like this:

python bootloader_verify.py <serial number> <COM port>

And see what it prints?

Best regards,

Edvin

The problem above is solved by following this case but now I'm facing another issue in step 10, It shows : Failed to upgrade target. Error is: Failed to establish connection. I have two nRF52832 Devkits (host and target), from step 5 to 9 I flashed all firmwares on both devices, in step 10 i just defined COM port for one of the devices to specify it as host device, I don't know if that's enough to say which device is the host or which is the target or there is another step that I'm missing, help please

Here is my cmd script : I used mesh SDK v2.0.0 provided in the case mentioned above

Possible causes:
- bootloader, SoftDevice or application on target does not match the requirements in the DFU package.
- baud rate or flow control is not the same as in the target bootloader.
- target is not in DFU mode. If using the SDK examples, press Button 4 and RESET and release both to enter DFU mode.
