我有一个 USB LTE 调制解调器“Brovi E3372-325”。有了它和 Raspberry Pi 4(最新的 Raspbian OS bookworm),我想使用 gammu 发送和检索短信。目前不需要 LTE 功能。
但是,gammu detect
似乎无法识别该调制解调器。
我遵循帕维尔的出色指导(https://blog.tanatos.org/posts/huawei_e3372h-325_brovi_with_linux_stickmode/)将调制解调器切换到固定模式。
运行mmcli -m 0
工作并返回调制解调器信息,包括系统信息:
System | device: /sys/devices/platform/scb/fd500000.pcie/pci0000:00/0000:00:00.0/0000:01:00.0/usb1/1-1/1-1.2
| drivers: option, cdc_ncm
| plugin: generic
| primary port: ttyUSB1
| ports: ttyUSB1 (at), ttyUSB2 (ignored), ttyUSB4 (ignored),
| usb0 (net)
运行 dmesg 返回

gammu-detect
列出了 ttyUSB1、ttyUSB2 和 ttyUSB3,但是gammu identify
无论端口如何,运行它都会导致超时。
我还将 ttyUSB1 设置为不受 NetworkManager 服务管理,这对解决我的问题没有帮助。
另外,我的固件版本为 3.0.2.61,没有可用的更新。
还有什么我可以检查或做的吗?
