If the modem has a port for communication and is presented in the system as 2cb70104 (VID and PID identifier on the USB bus) then the basic data can be shown. Lack of documentation makes it difficult to add full modem support.

I have its documentation. But all of them is in Chinese.

Hi @ChaingTsung
I tried to download before and nothing worked from what you shared.
Add the documentation normally here as a zip file attachment.

OFFICIAL Dial tools has been uploaded into https://github.com/ChaingTsung/Fibocom_dail_software_Linux.git. I built this tool for banana pi r3 with openwrt code and lede code. Although tool is sucessfully built, the tool is unavailable.(As long as you run this built dial tool,( named fibocom_dail and its path : /usr/bin/fibocom_dail), it says segments error.)

Thanks. It's quite useful, even though it's in Chinese :)

Show me:

cat /sys/kernel/debug/usb/devices

Install picocom (opkg update; opkg install picocom), try

picocom -b 115200 /dev/ttUSB0
picocom -b 115200 /dev/ttUSB1
picocom -b 115200 /dev/ttUSB2
picocom -b 115200 /dev/ttUSB3
etc

Type ATI, the modem should respond. If not, try the next interface (ttyUSB1, ttyUSB2 and so on). If modem respond, type and show output of

ATI
AT+CPIN?
AT+CSQ
AT+COPS=3,0;+COPS?
AT+COPS=3,2;+COPS?
AT+CREG=2;+CREG?"

谢谢。虽然是中文的，但还是很有用的：)

给我看看：

cat /sys/kernel/debug/usb/devices

安装 picocom（opkg 更新；opkg 安装 picocom），尝试

picocom -b 115200 /dev/ttUSB0
picocom -b 115200 /dev/ttUSB1
picocom -b 115200 /dev/ttUSB2
picocom -b 115200 /dev/ttUSB3
etc

输入 ATI，调制解调器应该响应。如果没有，请尝试下一个接口（ttyUSB1、ttyUSB2 等）。如果调制解调器响应，请键入并显示输出

ATI
AT+CPIN?
AT+CSQ
AT+COPS=3,0;+COPS?
AT+COPS=3,2;+COPS?
AT+CREG=2;+CREG?"
AT+GTCAINFO?
AT+GTCCINFO?
AT+MTSM=1
AT+MTSM=6
AT+MTSM=7

Unfortunately, the FM150-AE(version : 00) only runs via pcie bus, not usb. "/dev/mhi_DUN" is for AT. And all device descriptor for this module(version: 00) is starting with "mhi_"（ in '/dev' dir).

不幸的是，FM150-AE（版本：00）仅通过 PCIe 总线运行，而不是 USB。“/dev/mhi_DUN” 用于 AT。该模块（版本：00）的所有设备描述符均以 “mhi_” 开头（在 “/dev” 目录中）。

MHI 虚拟通道功能说明

编号 mhi 描述符功能
1 mhi_BHI 用于下载 firehose 文件的端口
2 mhi_DUN 用于 AT 命令的端口
3 mhi_LOOPBACK 用于测试环回的端口
4 mhi_DIAG 用于捕获 QXDM 日志的
端口 5 mhi_QMI0 用于传输 QMI 消息的端口
6 mhi_QMI1 保留
7 mhi_GNSS 用于获取和上传 GPS NEMA 的端口 data
8 mhi_EDL 固件升级端口（模块处于 edl 模式时开始枚举）

使用 picocom，而不是 echo。

not supported. @4lceG the driver dones not support fm150-ae( via pcie bus).

I tried to cross make it on x64 ubuntu.( target: banana pi r3) But the built driver can not work too.

Then I use lean code to build and choose fibicom mhi and quectel mhi. After built ,banan pi r3 run. I typed lspci -vvv in its terminal. The result of command lspci -vvv shoud return Kernel driver in use: fibo_mhi, but it returns Kernel driver in use: mhi_q. The driver code I uploaded passes on Ubuntu 20.04 x64 with kernel 5.15.125, however I do not know how to edit or modify its makefile for OpenWRT.

If I understand correctly, mhi is not supported and needs to be manually compiled in OpenWrt.

I found an interesting pdf that describes it > LINK < unfortunately I don't know where the necessary sources are on github.

不支持。@4lceG 驱动程序不支持 fm150-ae（通过 pcie 总线）。

如果我理解正确的话，mhi 不支持，需要在 OpenWrt 中手动编译。

我发现了一个有趣的 pdf 描述它> 链接 <不幸的是我不知道 github 上必要的来源在哪里。

As for quectel rm 50x series, most of them can be run via usb or pcie, just use AT commands to change.Most of quectel 5g module supports usb and pcie as if it consists of Qualcomm sdx55 or sdx65.

If the kernel is 6.x, the module can not work. It seems a lot of APIs to 'net' has been changed. And default kernel pcie mhi module does not make this 5G module work. So do the dial tools.

No message returns after input these at command. The driver does not work! So no reply for at command.

It's not about the exact version of the modem, but about the procedure. After all, we want to talk to this modem somehow.

Please, this is NOT openwrt support. Just show us output of these AT command, And that's it - from the point of view of this project, these implementation details are irrelevant.

No message returns after input these at command. The driver does not work! So no reply for at command.

Show us this "no message".

请注意，这不是 openwrt 支持。只需向我们展示这些 AT 命令的输出，就这样 - 从这个项目的角度来看，这些实现细节是无关紧要的。

在命令中输入这些后不会返回任何消息。司机不工作！所以 at 命令没有回复。

向我们展示这个 “无消息”。

Okay, now I rebuilt the ofiicial, clean firmware used @4IceG drivers.Info in here.

although it was successfully identified( quectel and fibocom 150 use sdx55), it can not connect to net. rmnet_mhi0 and rmnet_mhi0.1 have no ip, no route.
