I want to send data from nrf51822 through UART TX to esp8266.

Question

Hello, 
 I am trying to send data from nrf51822 through UART TX to esp8266. I've gone through the app_uart examples and I can recieve data through RX but having difficulty sending data through TX.

I managed to get it working by changing APP_UART_FLOW_CONTROL_ ENABLE to 
 APP_UART_FLOW_CONTROL_ DISABLED 
 static void uart_init(void)
{
 uint32_t err_code;
 const app_uart_comm_params_t comm_params =
 {
 RX_PIN_NUMBER,
 TX_PIN_NUMBER,
 RTS_PIN_NUMBER,
 CTS_PIN_NUMBER,
 APP_UART_FLOW_CONTROL_DISABLED,
 false,
 UART_BAUDRATE_BAUDRATE_Baud9600
 };

 APP_UART_FIFO_INIT( &comm_params,
 UART_RX_BUF_SIZE,
 UART_TX_BUF_SIZE,
 uart_event_handle,
 APP_IRQ_PRIORITY_LOWEST,
 err_code);
 APP_ERROR_CHECK(err_code);
}
