Hi,

If you want to send a message from the smartphone to the server, then it's better if you just publish to the server's unicast address.

Hi,

My answers below.

[quote userid="15475" url="~/f/nordic-q-a/62874/client-to-server-data-transmit/256649"]Where do you call the code snippet above? And do you get the assert right away when calling generic_onoff_client_set function?[/quote]

I call the generic_onoff_client_set function in the main() loop. And i get the assert when i call the function.

[quote userid="15475" url="~/f/nordic-q-a/62874/client-to-server-data-transmit/256649"]It would also be helpful if you sent me the call stack when the assert occurs.[/quote]

I call the function here. It is in the main loop.

[quote userid="15475" url="~/f/nordic-q-a/62874/client-to-server-data-transmit/256649"]Can you also give me more details about your use-case? What are you trying to do?[/quote]

To explain, I'm trying to send a byte from the client to the server.
That byte comes from a smartphone application connected to the client through the proxy service. This proxy service communication works fine and I receive the byte in the client from the smartphone.
When I receive the byte I have to retransmit it to the server. This is where I try to call the generic_onoff_client_set function in the main() but this is where I get the error.

Is it clearer? Feel free to suggest another way to send data to the server if there is one.

Thanks

Do you get any errors when you remove this modification?

You should have the addr2line tool after installing SES. You should be able to find it here:

[Your location]\SEGGER\SEGGER Embedded Studio for ARM 4.52c\gcc\arm-none-eabi\bin

Add it to your PATH. Then you use the command above in your command prompt.

Hi i'm using the nrf5_SDK_for_Mesh_v4.1.0 and i modified the Light Switch example!

That is the only thing i modified. I tried to call the function and i'm getting that error. I even tried to call the button_press handler to simulate a button press but i have the same error.

Can you please tell me how to use that addr2line command? I'm new on this and i don't know very well how it works.

Thanks for your help!

Hi,

Which Mesh SDK are you using? Are you using the Light switch client example? Is this the only thing you have modified?

You can track the error to find which function causing the assert by using addr2line tool, the syntax is:

arm-none-eabi-addr2line -e filename.elf 0x2C4F2
