[quote user="yuyou"]1.is there a function for know has paired? [/quote]

If you want to know if a pairing procedure was completed, you can register authentication information callbacks

Snippet:

static void pairing_complete(struct bt_conn *conn, bool bonded)
{
LOG_INF("Pairing completed: %s, bonded: %d", log_addr(conn), bonded);
}

static void pairing_failed(struct bt_conn *conn, enum bt_security_err reason)
{
LOG_INF("Pairing failed conn: %s, reason %d %s", log_addr(conn), reason,
bt_security_err_to_str(reason));
}





static struct bt_conn_auth_info_cb conn_auth_info_callbacks = {
.pairing_complete = pairing_complete,
.pairing_failed = pairing_failed
};





err = bt_conn_auth_info_cb_register(&conn_auth_info_callbacks);
if (err) {
printk("Failed to register authorization info callbacks.\n");

2.nrf52820 system off take 36uA, how to reduce power consumption? see SCH as follow:

[/quote]

This seems like a new unrelated question. Please open a new case for the power consumption question.

thanks for reply,

tow questions:

1.is there a function for know has paired?

2.nrf52820 system off take 36uA, how to reduce power consumption? see SCH as follow:

static int disable_ds_1(const struct device *dev)

{

ARG_UNUSED(dev);

pm_policy_state_lock_get(PM_STATE_SOFT_OFF);// NCS2.0.0+

return 0;

}

SYS_INIT(disable_ds_1, PRE_KERNEL_2, 0);

void go_system_off(char n)

{

printk("%s system off (%d)\n", CONFIG_BOARD,n);

// Configure to generate PORT event (wakeup) on button 1 press.

nrf_gpio_cfg_input(NRF_DT_GPIOS_TO_PSEL(DT_NODELABEL(button0), gpios),NRF_GPIO_PIN_NOPULL);

nrf_gpio_cfg_sense_set(NRF_DT_GPIOS_TO_PSEL(DT_NODELABEL(button0), gpios),NRF_GPIO_PIN_SENSE_LOW);

const struct pm_state_info si = {PM_STATE_SOFT_OFF, 0, 0};

pm_state_force(0, &si);//1.9.99+

k_msleep(100);

}

Best regards

Hi!

Take a look at how the throughput sample is configured. That sample is configured for optimizing BLE throughput.
