将X-CUBE-CELLULAR移植到新的调制解调器和主机MCU上卡死该如何解决呢

问答对人有帮助，内容完整，我也想知道答案 0 我正在将 X-CUBE-CELLULAR 移植到新的调制解调器和主机 MCU。将命令“AT”发送到调制解调器时，我卡在了 AT 命令通道的初始调制解调器初始化中。调制解调器是 Nimbelink TC4NAG，主机 MCU 是 Nucleo 144 F429。流量控制在调制解调器上被禁用，并且没有使用流量控制。波特率为 115200。我以 BG96 调制解调器为例。我已经移植了蜂窝应用程序，我可以确认 UART 通信通道在调制解调器和 MCU 之间正常工作。我的问题是当 MCU 发出命令“AT”时，调制解调器响应的“OK”未被处理（就像调制解调器在等待整个“OK”响应之前关闭 UART RX 中断。我已经转在跟踪输出上，我可以看到 MCU 通过 UART 接收到的消息。在下面截取的代码的第 89 行，您将看到我第二次发送“AT”命令时，UART 在响应缓冲区中具有来自先前 AT 命令的响应的字符“O”。是否有超时设置可以调整以修复此行为？ ===== X-Cube-Cellular version : X-CUBE-CELLULAR-6.0.0 ===== -----> New State: BOOT_STATE <----- TC4NAG UART config: BaudRate=115200 / HW flow ctrl=0 CS:CELLULAR_reset_socket_context ********* modem state : CA_MODEM_POWER_OFF IPC:IPC channel 0x20003a80 registered IPC:state 0x1 IPC:active channel handle: 0x20003a80 IPC:inactive channel handle: 0 IPC:HAL_UART_Receive_IT error UTILS:ppposif_client_config ComLib: sim state: rt_state:3 index_slot:0 sim_status:8 =====>CST_notif_callback (Data Cache event=0) =====>CST_notif_callback (Data Cache event=3) <<< Echoclt 1: wait data is ready to get date and time from network!>>> ATCore: AUTOM TASK: BOOT_STATE - NO_EVENT ============ CST_cellular_service_task : autom_event = no event AUTOM TASK: BOOT_STATE - BOOT_EVENT ******* CST_boot_event_mngt **** -----> New State: MODEM_INIT_STATE <----- AUTOM TASK: MODEM_INIT_STATE - MODEM_INIT_EVENT ******* CST_init_state_mngt **** SysCtrl_NL_TC4NAG :Modem Status ON when Power OFF SysCtrl_NL_TC4NAG :Waiting 30000 millisec for modem running...

答案对人有帮助，有参考价值 0 我在 Sysctrl power on 函数中切换了 Power up 和 Open channel 的顺序。恢复到原来的顺序，即 1) 通电 2) 打开 Uart 通道似乎已经解决了这个问题。
