进程启动延迟

测试过程中发现，系统启动后，jet_5g进程很久都没有运行

为什么从进程启动到

在主循环中的每个函数之前添加打印：

	Line 41: 2024-11-13 14:38:20.253910 [NR] [warning]: jet_5g start
	Line 42: 2024-11-13 14:38:20.280326 [NR] [warning]: before nr_read_uci_config

 发现nr_check_mod_connect_state中停留了17秒。

    Line 47: 2024-11-13 14:38:20.299390 [NR] [warning]: before nr_check_mod_connect_state
    Line 56: 2024-11-13 14:38:37.498089 [NR] [warning]: before nr_check_net_type

加调试信息发现，是因为lsusb还没有识别到模组导致在nr_check_mod_connect_state挂起。

开启后路由模式AT

AT+QROUTINGBH =1 : 开始后路由模式

AT+QROUTINGBH =1 ：关闭后路由模式

发射功率控制

AT+SP5GCMDS=”set nr power_control”,0,x  ps:x表示降功率的值，x=0是恢复  试试吧
