Add USB identification

Add configuration to config.txt

echo -e "enable_uart=1 \notg_mode=1" >> /boot/config.txt
You can also modify the config.txt in the boot partition directly on Windows.

Install ipk package

opkg update
opkg install usb-modeswitch kmod-mii kmod-usb-net kmod-usb-wdm kmod-usb-net-qmi-wwan uqmi

Optional ipk package

ADD SUPPORT FOR MBIM DEVICES

kmod-usb-net-cdc-mbim Kernel module for MBIM Devices
umbim MBIM modem utility

opkg update
opkg install kmod-usb-net-cdc-mbim umbim

ADD SUPPORT FOR PC INTERFACE (TTYUSB0) - YOU NEED IT IF YOU WANT TO SEND AT COMMANDS, FOR EG. TO CHECK YOUR BALANCE BY USSD.

• kmod-usb-serial-option
• kmod-usb-serial
• kmod-usb-serial-wwan

opkg update
opkg install kmod-usb-serial-option kmod-usb-serial kmod-usb-serial-wwan

Check if the device exists

Install the lsusb command, which is optional

opkg update
opkg install usbutils

Restart the device to apply the driver

lsusb

Compile the dial-up software

Download Quectel_QConnectManager_Linux software dial

Quectel_QConnectManager_Linux

Because the system space is expanded, choose to directly decompress this compressed package on the openwrt device

opkg update && opkg install unzip make gcc
#解压压缩包
unzip Quectel_QConnectManager_Linux_V1.6.0.16.zip

Compile

During the compilation process, it was found that two lib libraries were missing pthread.dl

Choose to copy two libraries directly from the toolchain to the device

Download the toolchain and unzip it to the Linux system

# 文件位置
# pthread
<YourPath>/openwrt-toolchain-22.03.2-bcm27xx-bcm2711_gcc-11.2.0_musl.Linux-x86_64/toolchain-aarch64_cortex-a72_gcc-11.2.0_musl/lib/libpthread.a
# dl
<YourPath>/openwrt-toolchain-22.03.2-bcm27xx-bcm2711_gcc-11.2.0_musl.Linux-x86_64/toolchain-aarch64_cortex-a72_gcc-11.2.0_musl/lib/libdl.a

Put these two files /usr/libin the openwrt system directory, then enter the folder where you just unzipped the dial-up software and execute the make command

cd quectel-CM
make release

Wait for the execution to end and you will get quectel-CMthe binary file. You can dial after execution.

./quectel-CM

To insert the card, you need a card slot.
