nRF Mesh DFU over the air

[lidorelias3]

Hello,
I'm trying to set up the DFU over the air mesh. Using the mesh SDK 5 and nRF SDK 7.1.0.

Using the DFU example from nrf sdk17.1.0, I successfully ran it.

When I tried to execute the DFU example located in mesh_sdk5, I cannot find my board via NRF connect app and cannot send a DFU package.

After reading some documentation, I have not been able to add DFU features to my application.

How do I add DFU over the air to my mesh network application?

Is it necessary to use the DFU bootloader and then add the application that uses buttonless DFU over mesh on top of it?  If so, how can I connect all this in Segger studio?

On nRF52832, I am using NRF SDK 7.1 and mesh SDK 5.

I appreciate your help in advance!

How did you change your ram start address? Can you show me a screenshot?
You should only need to send the application serial to one device. The other devices in the network with the same application ID and application key in their device page. But the device page must also be flashed on all other devices.

And in the .emProject file I have the macro called RAM_START. So I changed it to 0x20002DF0.
When run again it stays on the old address

Does the application key means the public encryption key? where does the public and private keys which I generated and concated in the .json file stored?

Did you do any changes to the flash_placement file? If so, try to revert those changes.

I take it you are using SES, then.

Did you remember to select "Common" from the drop down menu before changing the start address?

It worked!

However, I am unable to send the DFU package since it gets stacked on the Sending DFU init packet step:

Failed to upgrade target. Error is: Device returned an unknown status code (142) on a DFU state beacon packet.

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.
- if the error is ERROR_BUSY at the beginning of the DFU process,increase the value of PAGE_ERASE_TIME_MAX by few milliseconds.
Closing serial port...

Could it be related to the private/public key?

Does it stop after line 31, or did you just crop the output?

It may be caused by the keys. Did you generate your own keypair and use them in the devicepages?
