@David: I have reported the issue to our R&D team. Will let you know if I hear anything from them.

Yep. I have tried. Unfortunately not much success.

The only complement : nrf_mesh_node_config.c, 108, Softdevice assert: 1:136746:0. But it was already displayed in original post.

I'll dig a bit more.

You should use addr2line -e yourapplication.elf address

Not the softdevice.hex file.

So back on a linux Machine. I might be confused on the way using addr2line. because the only answer I get is ??:0

addr2line -e s132_nrf52_5.0.0_softdevice.hex 136746

So, compiling on a Mac, flashing using nrfjprog and doing a nrfjprog -e to erase the chip.

I'll dig a bit more... But any directions in which to look for would be appreciated.

Cheers,

Hi Hung Bui,

The chip is erased. I am sure and positive about it.

The issue to be more precise is the following : The device on which I am flashing the code is working for about 2 minutes. And then the error comes. All happens after the device is provisionned. I do not change the code between the DevKit and the Device.

Regarding addr2line, I am on MacOS and the tool is not accessible in a straight forward manner. So beginning of next week, I'll find out a linux machine to try. ATOS may be an option but I can't use it on the Stack hex file...

Regards.

Hi David,

Please make sure you erased the chip before you test. Data from previous firmware may mess up with the flash manager in mesh.

If the issue persists, please use addr2line (addr2line -e filename <address>) to find where the error is thrown from.

Dear all,

We are currently experiencing the same issue.

So, we have tested the Light / Switch example on the devKits and everything is working correctly. 1 Switch and 2 servers (the server count has been set to 2).

We have installed the code on other boards (same nrf52832 QFAA) and the code crashes with the same error... Our board runs the 32kHz crystal.

We are using the latest NRF SDK for Mesh.

Any idea on what may happen ? I would be happy to hear a solution has been found.

Regards,

David

I was asking about the 32kHz crystal, not the 32MHz crystal.

Have you tried to run a normal nRF5 SDK example ? for example ble_app_hrs on the board ? Seems more like hardware issue.

Hi! Hung, Sorry for my delay in response. Yes, I did try it without any modification also. It's still the same.

The module has an external 32MHz crystal for the nRF52832 chipset. Still any changes are required?

The Softdevice that I am working with is s132 and using the _nRF52832_xxAA_s132_5_0_0.emProject files. (Already tried _s132_3_1_0 file also. That doesn't work at all.)

This particular board shows this same Softdevice assert error even with all the other examples also. But if I try to use another pieces of exactly the same board, the _s132_5_0_0 examples run seamlessly. So, looks like maybe it could be some hardware bug as well but not sure of what!

Hi Gaurav,

I tested here the example in Mesh SDK v1.0 worked just fine. Have you tried to test without any modification ? (you don't have to change the number of server)

Do you have 32kHz crystal with the module ? Our example use 32kHz crystal in the configuration for the softdevice I assume you modified it if you don't have the crystal ?

Could you let me know which Softdevice you used ?

Hi! Hung Bui, I have attached the RTTViewer Screenshot of both the servers and the client. As soon as this softdevice assertion is made, the node goes to sleep as mentioned in nrf_mesh_node_config.c but I still don't understand why this is happening and why to just one of the nodes. Please help.

Could you capture a screenshot when you receive the error? "Softdevice assert: 1:136746:0" doesn't look very familiar to me, usually it's the address in flash of the function throw the error.

In the newer (from SDK v10.0) you don't need 3 server to make the demo works. You don't need to modify anything, the provisioner works as a light switch client even with just 1 server.
