UART implementation in light_switch_client code

[Sachin]

I want to interface Client Sensor over UART in light_switch_client code. Can you please give me the idea,how to do it.

I am using Mesh_V4.0 and SDK 16.0

It suspect that you haven't setup your MESH_ROOT macro correctly. Take a look at step 3) under "Testing the example" and check that the correct path is inserted.

Is this correct ? I have created a folder "nRF_mesh " inside which I have copied my mesh stack

Hi thanks for the reply.It compiled successfully.

1.Now will you please explain me which part in the code exhibits UART functionality ? Basically I want to send some commands from development kit,for which my sensor will send the response. (PHYSICAL WIRED INTERFACE)

2,Which pins I should use on the development kit  to interface my external sensor ? (External sensor has RX,TX,RTS,CTS pins).

Hi,

1. For sending and receiving over UART, have a look at these functions:

app_uart_get(..)

app_uart_put(..)

2. I suggest you have a look at the Product Specification for the nRF52832. P0.05 - P0.08 are connected to the interface MCU. Choose some other GPIO for communicating with the sensor. 

Initialize the UART module with uart_init().
