Relay in mesh DFU

[Sama]

Hi,

I have an nRF52840 DevKit and dongle and am using SDK for mesh v.5 with SDK 17.0.2.

I want to update the firmware in a mesh network and am working on the mesh DFU example using DevKit connected to pc and dongle which will receive the file through the mesh.

I run the example successfully and it worked. 

Now I want to send the firmware to a specific node in the mesh network. So I used different application IDs for DevKit (1) and dongle (2) in the generation of the device page and zip file.

I tried to send the zip file to the dongle but that did not work. 

Here is the log:

I have searched the devzone and found this ticket like my case. 

In this case, it was suggested to use a patch file which is for SDK v4.0.

Should I use an updated patch file for SDK v5?

Could you please advise me to solve the problem?

Hi,

From your logs it seems like the DFU was successful. But the firmware on the dongle was not update? Am I understanding this correctly? The LED is not toggling?

Hi, 

What specifically did you flash on the device connected to PC? and can you reproduce the issue using our example?

Hi,

I am sorry for my late reply.

What I did is:

1. I produced the private key and public key and then the device page different for DevKit and dongle.

2. I flashed the DevKit by:
    a. SoftDevice.
    b. dfu_nrf52840_xxAA_s140_7_2_0 from example folder.
    c. Device page.
    d. mesh_bootloader_serial_gccarmemb_nrf52840_xxAA.

3. and flashed the dongle by:
    a. SoftDevice.
    b. dfu_no_serial_nrf52840_xxAA_s140_7_2_0 from example folder.
    c. Device page.
    d. mesh_bootloader_gccarmemb_nrf52840_xxAA.

4. I produced the test_file.zip by using the bliny example for the dongle and tried to send that. I considered that the zip.file should be produced so that it matches with the device page of the dongle. However, the firmware of the dongle was not updated.
