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

Hi just to check UART part I am using UART code from examples\peripheral folder.To check the loopback I short default UART pins 6 to 8 and 7 to 9 and it worked.

Now in the same code in uart_init() function I changed RX,TX,RTS,CTS to 31,30,29,28 and short RX toTX and RTS to CTS but I am not  getting any loopback data now.

 I can not use 28,29,30,31 (P0) for uart functionality ? I also tried with 18,19,20,21 but it did not happen.

Please help

You should be able to use these pins for UART. I also noticed another case which is the same as one, I suggest you have a look at that thread.

Also regarding the pins, sorry to confuse you but you should be able to use the pins 5,6,7,8 also.
