SETTINGS_STATIC_HANDLER_DEFINE(ble_qos, MODULE_NAME, NULL, settings_set, NULL,NULL); so how i have to call it ?

Hi ,

You can implement the following code to call it.

#include <zephyr/settings/settings.h>

static uint32_t ble_interval;

static int ble_qos_set(const char *key, size_t len,
settings_read_cb read_cb, void *cb_arg)
{
const char *next;
int rc;

if (settings_name_steq(key, "interval", &next) && !next) {
if (len != sizeof(ble_interval)) {
return -EINVAL;
}
rc = read_cb(cb_arg, &ble_interval, sizeof(ble_interval));
if (rc >= 0) {
return 0;
}
return rc;
}

return -ENOENT;
}

SETTINGS_STATIC_HANDLER_DEFINE(ble_qos, "ble_qos", NULL, ble_qos_set, NULL, NULL);

int main(void)
{
settings_subsys_init();
settings_load();
// ble_interval is now restored from storage

// Update the value and save it
ble_interval = 100;
settings_save_one("ble_qos/interval", &ble_interval, sizeof(ble_interval));
}

Call it after settings_subsys_init() and whenever the value changes and needs to be persisted.

Please let me know if you have any issues while implementing.
