struct upgrade_server_info {
uint8 ip[4];
uint16 port;
uint8 upgrade_flag;
uint8 pre_version[8];
uint8 upgrade_version[8];
uint32 check_times;
uint8 *url;
upgrade_states_check_callback check_cb;
struct espconn *pespconn;
};
这个结构体体中已经有ip,port,pespconn这个结构体又是什么作用?需要赋哪些值?
ota升级的库中,结构体upgrade_server_info中pespconn的作用?
