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?

You can also take a look at this infocenter link. In the link you provided, there is a zip file with the whole example code. I would suggest to download it & see how the main.c code is implemented.

 I've download the zip file and try to do it as you said, and I build it without problem after added the necessary paths. But when I debug the program I get the assert as below:

<t: 30>, main.c, 762, ----- BLE Mesh Light Switch Server Demo -----
<warning> nrf_sdh_ble: RAM starts at 0x20002A68, can be adjusted to 0x20002760.
<warning> nrf_sdh_ble: RAM size can be adjusted to 0xD8A0.
<info> app: UART Start!
<error> app: ERROR 7 [NRF_ERROR_INVALID_PARAM] at F:\mesh tools\nRF5_SDK_14.2.0_17b948a\examples\ble_peripheral\ble_app_uart_Mesh\main.c:773

I don't the reason.

I mean that I don't know how to resolve it

You should try to adjust the RAM size like described. Go to Project -> Edit Options in SES, then click on the Common Configuration, go to the Linker section & double click on Section Placement Macros. There, you can change the RAM start & size values.

Now I  combine the light switch client demo in mesh sdk1.0.1 with peripheral uart demo of sdk14.2.  I added the mesh sdk in nRF5_SDK_14.2.0_17b948a\components\mesh and removed the sdk14.2 from  F:\nrf5_SDK_for_Mesh_v1.0.1_src\external ,also I added & changed the path of these files. But I got some errors after that as follows:

Coule you help me to solve the problem?
