Mesh SDK light switch example combining client and server

[shenghua]

Hi All:

We are using nRF52840 SDK with BLE Mesh sdk5.0 to develop bluetooth mesh and we can use light_sw_client to control the LED1 state on the light_sw_sever via BLE Mesh APP and   nRF52840_DK.

Now we hope to integrated the ight_sw_client and  light_sw_sever to implement bi-direction data transfer between two nRF52840_DK.

The integrated light_sw client and server can be compliled successfully,but executing the mesh_stack_init function has a error message( Mesh error 5 at 0x00027B49) from the function of "ERROR_CHECK(generic_onoff_client_init(&m_clients[i], i + 1))".

How to debug the issue? Thanks a lot.

Hi,

Getting Mesh error 5 (NRF_ERROR_NOT_FOUND) from generic_onoff_client_init() function means invalid access element index. Can you check that the element index is correct?

Dear Mttrinh:

Thanks your support.

We integrated the following codes of light_sw_client to light_sw_sever in models_init_cb function.

In debug procedure, we found that the element_index is 1 and 2 in the "generic_onoff_client_init"; and the element_index is 1 in "generic_onoff_server_init".

Best Regards,

Sheng-Hua
