RE: BLE stops advertising once changed UART tx and rx pin

"not giving advertisement". 99.9% of the time that means you're in the error handler. So put a breakpoint there and find out which system call gave you an error and why.

Here is Piece of UART CODE

static void uart_init(void)
{
	
	 /**@snippet [UART Initialization] */
    simple_uart_config(RTS_PIN_NUMBER, TX_PIN_NUMBER, CTS_PIN_NUMBER, RX_PIN_NUMBER, HWFC);
    
    NRF_UART0->INTENSET = UART_INTENSET_RXDRDY_Enabled << UART_INTENSET_RXDRDY_Pos;
    
    NVIC_SetPriority(UART0_IRQn, APP_IRQ_PRIORITY_LOW);
    NVIC_EnableIRQ(UART0_IRQn);
    /**@snippet [UART Initialization] */
	}

Here I change RX and TX pin

#define RX_PIN_NUMBER  11
#define TX_PIN_NUMBER  9
#define CTS_PIN_NUMBER 10
#define RTS_PIN_NUMBER 8
#define HWFC           true

Here is pin config in pca10028.h file, if i keep RX and TX 11 and 9 as default works properly, but if change pins , not giving advertisement

can you share the piece of code you are using?
