Mesh DFU

[him]

Hi Team,

I am using nrf52833DK, nRF5 SDK for Mesh v4.2.0 and nRF5 SDK v16.0.0.

I am trying to implement mesh DFU, but the DFU is stuck at the 35th segment. When I probed the serial port I found out that the target is not sending ack.

I have also tried implementing DFU only with the softdevice, serial_bootloader, and device page. Still the same result.

Here is the log of the windows PowerShell.

PS C:\Users\Loka\Desktop\New folder (2)\New folder\bin\blinky> nrfutil --verbose dfu serial -pkg dfu_test.zip -p COM16 -b 115200 -fc --mesh

I have successfully implemented DFU sometime ago, but now it is not working properly. 

I have tried reinstalling python2.7, nrfutil and also used fresh SDK's. Still no success.

Image of serial port last packet. The last acknowledgement from the target is incomplete or incorrect.

Please suggest an appropriate solution for this. 

Thanks

Hey Himanshu!

That is odd. So you've tried to it several times, and it is always the 35th segment? Could you tell me more about the network and what type of node this is? Is it for instance based on any particular NCS sample?

Best regards,

Hi Elfving,

I have tried DFU with nrf52832 and it worked. The device was successfully programmed.

Don't know why it is not working with nrf52833.

Hi Elfving,

The issue is resolved.

The serial link was causing this issue.

I double-checked my serial connections and tried with 2 development kits, but stuck with the same problem. However, it worked perfectly with the COM port of the DK.

Don't know why this happened?

Thanks for your support.

Best regards,

Hi Himanshu!

I am so glad it got resolved! I'm a little uncertain about in what way serial connections made this happen though. Which connection are you referring to?

Best regards,

Hi Elfving,

I used a USB to Serial module to send DFU from PC to serial DFU node.

I have used the same module some time ago and it worked perfectly fine, don't know why it didn't work this time however it is working with nRF52832.

Best regards,

Himanshu

Strange. Good thing that the main issue is resolved though.

Feel free to ask if you want further help with this, though if it isn't mesh related maybe it should be in a new ticket.
