i was using the serial example in examples/peripheral/serial and i Want to display integer value int i=1234 on the serial terminal(putty).I want to convert the int value to string.
i was using the serial example in examples/peripheral/serial and i Want to display integer value int i=1234 on the serial terminal(putty).I want to convert the int value to string.
if i use it in the serial program it is not working.
.
int main(void)
{
ret_code_t ret;

bsp_board_buttons_init();
ret = nrf_serial_init(&serial_uart, &m_uart0_drv_config, &serial_config);
APP_ERROR_CHECK(ret);

}
}
which sdk version you are using?
sdk 14.2.0
it is working perfectly fine..i have checked it..
