半自助旅游旅行社BR不执行TCP_IP事件,,一点儿也不PROCESS_YIELD那张之后(Cont

2019-09-30 03:12发布

我想在6LoWPAN的边界路由器来实现ECC。 我使用的半自助旅游旅行社Wismote微尘所有udp_sender.c作为发件人和边界路由器(border_router.c)需要接收一些信息,也回复ECC密钥。 我已经停用makefile中并启用debug_print默认的服务器(WITH_WEBSERVER = 0)。

udp_sender.c正确地发送消息,但边界路由器没有收到消息。 没有后执行PROCESS_YIELD在border_router.c

while(1) {
     PROCESS_YIELD(); **//Nothing executes from this point**
     if(ev == tcpip_event) {
          tcpip_handler();
     } else if (ev == sensors_event && data == &button_sensor) {
          PRINTF("Initiaing global repair\n");
          rpl_repair_root(RPL_DEFAULT_INSTANCE);
     }
 }
