调试RG255AA USB转串口不识别

BiaoWang-Q · 2025 年9 月 10 日 08:50

哪个运营商的SIM卡？

13579 · 2025 年9 月 10 日 08:53

用的是移动的5G卡

BiaoWang-Q · 2025 年9 月 10 日 08:54

AT+CGDCONT=1,"IP","cmnet"
AT+QICSGP=1,1,"cmnet"

配置下APN，然后再测试下
AT+QIACT=1
AT+QPING=1,“223.5.5.5”

如果还是不行，试试换个SIM卡能否正常工作吧。

screenshot_2025-09-10_16-56-37 现在行了
但是拨号我试了下还是能拨号不能ping外网咋回事

BiaoWang-Q · 2025 年9 月 10 日 11:56

将完整的pppd 的日志发下。
再试试usbnet 拨号吧。

这个不能切换到0 使用GobiNet 驱动驱动下没有/dev/qcqmiX 如果我想试试ECM驱动应该操作？

BiaoWang-Q · 2025 年9 月 11 日 02:25

可以用ECM，usbnet设置成0.
这个是过程的奥捷芯片，不支持QMI.

13579 · 2025 年9 月 11 日 05:26

这个不支持设置成usbnet 0啊看下我发的

BiaoWang-Q · 2025 年9 月 11 日 06:37

不支持qmi，就是不支持usbnet设置成0

13579 · 2025 年9 月 11 日 08:00

我用ECM的话usbnet是设为1 然后 AT+CGDCONT=1,“IP”,“cmnet” 然后 AT+QNETDEVCTL=1,1,1 再然后udhcpc获取对应网口ip 是这个流程吗

BiaoWang-Q · 2025 年9 月 11 日 09:23

还要发AT
AT+QNETDEVCTL=1,1,1 拨号

13579 · 2025 年9 月 12 日 02:47

screenshot_2025-09-12_10-43-50

这是啥情况发送AT+QNETDEVCTL=1,1,1 返回错误

BiaoWang-Q · 2025 年9 月 12 日 09:40

AT+QNETDEVCTL?
AT+QNETDEVCTL=?
分别查询下看看

13579 · 2025 年9 月 14 日 02:23

screenshot_2025-09-13_10-08-45

BiaoWang-Q · 2025 年9 月 14 日 02:26

AT+CGPADDR
也查询下。不要启动ppp 拨号，可以用quectel-CM试试。

13579 · 2025 年9 月 15 日 03:21

AT+CGPADDR命令
screenshot_2025-09-15_09-09-04
使用quectel-CM 报错
quectelcm
没招了救命

BiaoWang-Q · 2025 年9 月 15 日 04:06

查询下AT+CGPADDR 吧。这个指令返回啥了。
需要升级下固件和quectel-CM.

13579 · 2025 年9 月 15 日 05:57

固件和quectel-CM都更新后使用quectel-CM直接拨号但是设备测的网口拿不到ip log如下：

解决了查了一顿发现是之前用的EC20模块经常掉线为了稳定把usb口限制为12M了
RG255AA改回480M就解决了但是现场用高速经常出问题还是得适配12M

BiaoWang-Q · 2025 年9 月 15 日 13:35

USB掉线不应该将模块限制在12M。许多模块在12M不能完整工作。
