Hi again.

A actually a little unsure what the issue might be.

Could you try with the latest release, and the Mesh light example there?

Ok, thanks.

I'll forward this to our Mesh developers, so that they can have a look. Maybe they have seen something similar.

Let me get back to you with some information from them.

Hi Joakim,

I'm using "Makerdiary.com nRF52840-MDK" development board. It's supported by Zephyr.

This board uses pyOCD, and is not compatible with nrfjprog or the nrF Connect programmer (It uses DAPLink programmer/debugger)

Maybe a function that "forget" the mesh network would be helpful but I don't know if it's implemented. Also trying to erase the setting would be another way to test, using "settings_delete()" function, but it requires the "Name/key" of the settings item as an input parameter, which I don't have.

Best regards

I don't have any experience using pyOCD, but there might be some "garbage" left on the chip if you aren't able to perform a complete erase.

Are you working with a custom board, or the nRF52840-DK?

Maybe you could try erasing the board using nrfjprog or the nRF Connect programmer app?

Joakim

Hi Joakim,

Thanks for answer.

- No, I didn't make any modifications to the code.

- With respect to the warning message "Ignoring data for unknown CID 0x003a": Maybe something happens inside the mesh library when it loads persistent data thru the "settings_load()" function. Before testing with this sample code I tried with other examples and samples codes. One was an example from a "developer study guide" from Bluetooth SIG, and the others were from the Zephyr's samples. None of the previous codes gave me good results. Maybe all this codes stores persistent data into the nrf52 and is loaded somehow now, giving me this warning message. My board use pyOCD programer. I tried to erase the whole chip but I'm not sure if it really doing it.

The command used to erase the chip was: "pyocd erase -v -t nrf52840 --mass"

Best regards

Hi.

I haven't seen the error message; "Ignoring data for unknown CID 0x003a" before.

Have you made any changes to the example? I can't find any reference to any 0x003a company identifier in the stock example. And I don't get the same error myself.

Yes, I belive that you are using static OOB. I can double check that to be sure.

Hi,

I was finally able to connect to my device and finish the provisioning process. I used the OOB method instead of push method (I missed that part of the documentation instructions, so it's my mistake).

I still have two questions

- Why the warning message "Ignoring data for unknown CID 0x003a" appears in the log?

- What kind of OOB method is used? Is it Statc OOB?. I ask because I didn't find something related to the OOB in the code (maybe I'm wrong)

Best regards
