Uart Tx works when merge with Nrf Mesh Dimmer, but Rx is not working

[bivay]

I configured Uart on 23 - Rx and 24 - Tx of NRF52832.

In simple uart example it works fine with uart_event_handle for rx.

But when this code is merged with Nrf Mesh Dimmer Code, I can transmit the data via tx pin, but there is no interrupt of Uart receive via "uart_event_handle",

Please Help me to solve this.

Issue solved by using app_uart_fifo instead of app_uart.

And Added:

//==========================================================
#ifndef APP_UART_ENABLED
#define APP_UART_ENABLED 1
#endif
// <o> APP_UART_DRIVER_INSTANCE  - UART instance used

// <0=> 0

#ifndef APP_UART_DRIVER_INSTANCE
#define APP_UART_DRIVER_INSTANCE 0
#endif

#ifndef APP_FIFO_ENABLED
#define APP_FIFO_ENABLED 1
#endif

in SDK_Config.h

Thank You
