Hi,my board is nRF52840,and the demo is periodic_sync_conn within ncs2.7.0,
I want to establish periodic sync with the AP whose rssi is better，but i am failed。The ESL will sync with another AP automatically 
Thanks.
struct _AP_info
{
int8_t sid;
int8_t rssi;
bt_addr_le_t addr;
} __packed;
static struct _AP_info AP_info={.rssi=-80};
static void scan_AP(const struct bt_le_scan_recv_info *info)
{
if (info->rssi > AP_info.rssi)
{
AP_info.sid = info->sid;
AP_info.rssi = info->rssi;
bt_addr_le_copy(&(AP_info.addr), info->addr);
printk("Get better rssi AP:sid=%d,rssi=%i,addr=0x%X\n", AP_info.sid, AP_info.rssi, AP_info.addr.a.val[0]);
}
}
static void scan_recv(const struct bt_le_scan_recv_info *info, struct net_buf_simple *buf)
{
char name[NAME_LEN] = {0};
char le_addr[BT_ADDR_LE_STR_LEN];
struct _AP_info *p_AP_info = NULL;
(void)memset(name, 0, sizeof(name));
bt_data_parse(buf, data_cb, name);
bt_addr_le_to_str(info->addr, le_addr, sizeof(le_addr));
if (0 == strstr(name, "PAwR conn sample") || 0 == info->interval){
return;
}
printk("scan_recv:%s,sid:%d,rssi:%i,type:%d,addr:%s\n", name, info->sid, info->rssi, info->addr->type, le_addr);
scan_AP(info);
if (!per_adv_found){
// per_sid = info->sid;
// bt_addr_le_copy(&per_addr, info->addr);
per_sid = AP_info.sid;
bt_addr_le_copy(&per_addr, &(AP_info.addr));
per_adv_found = true;
k_sem_give(&sem_per_adv);
}
}
static struct bt_le_scan_cb scan_callbacks = {
.recv = scan_recv,
};
