这取决于您使用哪个协议将数据从 tk103 设备发送到服务器,如果您使用 TCP/IP 协议,一旦数据来自设备,您应该使用命令重播。
您在设备中显示配置以询问或调用以请求命令。
我们的配置就像
1)imei:359710047059226,tracker,15/03/18 12:17,,F,121703.000,A,1255.2746,N,07736.8209,E,0.00,208.00,0.00,1,0;
id 设备发送此命令,我们仅存储到数据库
2) imei:359710047059226,tracker,15/03/18 12:17,,F,121703.000,A,1255.2746,N,07736.8209,E,0.00,208.00,0.00,1,1;
我们正在测试的最后一位数据
如果 0 表示仅使用 :OK 存储重播
如果 1 表示使用 :CMD GPRS 001 重播,就像某些命令一样
