How to communicate between PC and mesh client via uart

[zhengrui]

now I want to transfer  some data between  PC and the client of mesh,I have read this  case   and try to add the light switch client example to the uart example.but I don't know how to exchange the codes of main.c.Can you tell me how to do it?

I've solved  it by adding  some things like NRF52_SERIES to list of preprocessor symbols.

But whne I build my program it shows more errors about .o files. Just like this :

It shows there are many functions are undefined or multiple defined . I couldn't deal with it and can you help me?

Hi Bjorn,

I have solved it and I can build the program successfully if I remove three NRF_MODULE_ENABLED functions.

They are 

1://#if NRF_MODULE_ENABLED(UART)

 //#endif //NRF_MODULE_ENABLED(UART)

2://#if NRF_MODULE_ENABLED(APP_FIFO)

 //#endif //NRF_MODULE_ENABLED(APP_FIFO)

3://#if NRF_MODULE_ENABLED(APP_UART)

 //#endif //NRF_MODULE_ENABLED(APP_UART)

If I don't remove them I can't use the functions defined in them ( the codes are gray between  the #if  and #endif ). I tried it when I just use the demo of  peripheral uart in sdk v14.2 and the program worked successfully.

After built  it successfully , I can see the nrf_log doesn't work and the program stopped in ERROR_CHECK(sd_softdevice_enable(&lfc_cfg, softdevice_assert_handler));.

The mesh is not work.

The code is gray because the UART, APP_FIFO & APP_UART are not enabled in NRF_MODULE__ENABLED. You will have to enable these to stop the conditional preprocessor macros from being gray. It seems that the mesh does not work because the softdevice has not been enabled. I think you need to enable the modules first & then take it from there.

[zhengrui]

Yes you are right. But how to enable the softdevice  and UART etc,I can't find the codes to enable them .

[Bjørn Kvaale]

Go to sdk_config.h configuration wizard, open the nRF_Libraries tab & make sure APP_FIFO_ENABLED is true, APP_UART_ENABLED is true, etc. Then recompile & the conditional preprocessor macros should not be grey anymore.
