How parent node detects new child node join?

How parent node detects new child node join?
I have tried espconn_mesh_regist_conn_ready_cb but espconn_mesh_connect always error
and I have tried espconn_mesh_regist_usr_cb but it cause the root never connect to server

Is there any simple to detects a new child node join?

1. espconn_mesh_regist_usr_cb
when new child node joins, the system will call the user_callbak;

I have tried espconn_mesh_regist_usr_cb but it cause the root never connect to server.
If I remove this call, the connection is OK
Do you have a mesh_demo that root can connect to server after added espconn_mesh_regist_usr_cb.
My test is as follows:
void ICACHE_FLASH_ATTR test_mesh_usr_callback(void *arg){
MESH_DEMO_PRINT("test_mesh_usr_callback\n");
}
void ICACHE_FLASH_ATTR test_mesh_conn_ready_cb(void *arg){
MESH_DEMO_PRINT("test_mesh_conn_ready_cb\n");
}
void ICACHE_FLASH_ATTR mesh_enable_cb(int8_t res){
if (res == MESH_OP_FAILURE) {
MESH_DEMO_PRINT("mesh_enable_cb = enable mesh fail\n");
espconn_mesh_enable(mesh_enable_cb, MESH_LOCAL);
return;
}

We have post the demo to detect new child joins mesh.
