DSPS can not need CTS RTS pin or not

Hi,all.

In dsps project "DA14580_DSPS_3.150.2" ,perpheral device.

My setup is follow:
#define CFG_LP_CLK 0xAA //no 32.768k crystal ,so set 0XAA
#define CFG_UART_HW_FLOW_CTRL
#define CFG_EXT_SLEEP

void set_pad_functions(void) // set gpio port function mode
{
GPIO_ConfigurePin( UART1_TX_PORT, UART1_TX_PIN, OUTPUT, PID_UART1_TX, false );
GPIO_ConfigurePin( UART1_RX_PORT, UART1_RX_PIN, INPUT_PULLUP, PID_UART1_RX, false );
#if (UART_HW_FLOW_ENABLED)
GPIO_CONFIGUREPIN（UART1_RTS_PORT，UART1_RTS_PIN，OUTPUT，PID_UART1_RTSN，FALSE）;
GPIO_ConfigurePin (UART1_CTS_PORT UART1_CTS_PIN,INPUT_PULLUP, PID_UART1_CTSN, false );
#endif /*UART_HW_FLOW_ENABLED*/
//GPIO_ConfigurePin(GPIO_BUTTON_PORT,GPIO_BUTTON_PIN,INPUT_PULLDOWN, PID_GPIO, false);
}

PC UART < -----Flow1----> BLE UART <-----Flow2------> Phone.
I want to do is:
first step:
judge Flow1 is right or not.
In BLE UART ,I get data from pc,then i judge the flow data is right and then send a tips back to pc by uart.
So ,I used pc to send BLE a data every second,but the tips is not every second back to pc.
I think the reason is the sleep and flow control,because when i close sleep and close flow control,the data is response Immediate.
I want response Immediate,and open sleep and open flow control.
How to do to solve this problem?

second step:
judge Flow2 data is not lost or wrong bit .
every phone send a data to UART,the data have a crc ckeck in the end.
this is in testing now.

please give me help.
thanks.

Hi,all
CTS i used to wake_up_irq ,when the uart have data to BLE,then let the CTS GPIO high to low to active ble,
app_force_active_mode();

when data have translated over,then let the CTS GPIO low to high,the ble to sleep.
app_restore_sleep_mode（）;

the wake_up_irq is not work normal ,I test when the CTS GPIO is high to low,not always go in to wake_up_irq to the app_force_active_mode();

why ?

can you help me?

hi , MT_dialog,

Yes ,i have set like this:
在void periph_init（空白）
{
.........
app_button_enable();
........
}

in void app_button_enable(void)
{
wkupct_register_callback(app_button_press_cb);
if(uart_cts_init_flag==FALSE)
{
gpio_configurepin（uart1_cts_port，uart1_cts_pin，input_pullup，pid_uart1_ctsn，true）;
wkupct_enable_irq(0X80, 0X80, 1, 0);
uart_cts_init_flag=TRUE;
}
else
{
if(uart_cts_irq_flag ==FALSE)
//if (GPIO_GetPinStatus( GPIO_BUTTON_PORT, GPIO_BUTTON_PIN )!=FALSE)
{
gpio_configurepin（uart1_cts_port，uart1_cts_pin，input_pullup，pid_uart1_ctsn，true）;
wkupct_enable_irq(0X80, 0X80, 1, 0);
}
else
{
GPIO_ConfigurePin (UART1_CTS_PORT UART1_CTS_PIN,INPUT_PULLUP, PID_UART1_CTSN, false);
wkupct_enable_irq(0X80, 0, 1, 0);
}
}
}

in void app_button_press_cb(void)
{
if（getBits16（sys_stat_reg，per_is_down））
periph_init();

if (app_ble_ext_wakeup_get())
{
//Wakeup BLE here

#if (EXT_SLEEP_ENABLED)
app_set_extended_sleep();
#elif (DEEP_SLEEP_ENABLED)
app_set_deep_sleep();
#else
app_disable_sleep();
#endif

SetBits32(GP_CONTROL_REG, BLE_WAKEUP_REQ, 1);
app_ble_ext_wakeup_off();
}
if (GPIO_GetPinStatus( GPIO_BUTTON_PORT, GPIO_BUTTON_PIN )!=FALSE)
{
uart_cts_irq_flag =FALSE;
UART_CTS_IRQ_LASTDOWN = 0;
uart_cts_irq_lastup =1;
uart_sps_flow_off();
app_restore_sleep_mode（）;
}
else
{
app_force_active_mode();
uart_cts_irq_lastdown =1;
uart_cts_irq_lastup =0;
uart_cts_irq_flag =TRUE;
uart_sps_flow_on();
}
app_button_enable();
}

in app_button_enable()
uart_cts_init_flag==FALSE is only for power on set,then set wake_up_irq in app_button_enable() is as the same with app_button_press_cb.

thanks.

the wake_up_irq is not work normal ,I test when the CTS GPIO is high to low,not always go in to wake_up_irq to the app_force_active_mode();

why ?

can you help me?
thanks.

Hi,MT_dialog,
I set the irq and the wake up controller every time before the da goes sleep ,like follow.

in void app_button_press_cb(void)
{
if（getBits16（sys_stat_reg，per_is_down））
periph_init();
............
}
