How to use BPI-4G LTE module with BPI-R2
Get startting

1.Firstly, use R2 connects LTE module by USB or 14pin Headers. then execute command "lsusb" to have a look if R2 have drove the module. The red box is the id of 4G module.
After seeing this, execute command "ls /dev/ttyUSB*" to make sure the 4G module have been recognised as USB devs.
2. Execute the "./ppp1.sh &"
then execute command “ifconfig -a”，you will see ppp0
3. Execute command ”wget -O speedtest-cli https://raw.githubusercontent.com/sivel/speedtest-cli/master/speedtest.py” to download speed test tool.
4. Execute command "chmod +x speedtest-cli", then execute "./speedtest-cli"

FAQ
- (1) You could get ppp1.sh from here : https://pan.baidu.com/s/1yu0nTNQKPNPzprVPjhOPUA
- (2) Q: What should I do, if you meet this "expect (OK) ^M alarm Failed "
- A:The root cause is the Modem.service has used the module usbserial, so the 4G module can’t use usbserial; we can solve the problem by using command "systemctl disable ModemManager.service " or "systemctl stop ModemManager.service "
- (3) Q：How to test the communication between SIM card and 4G module？
- A:Use minicom， ”minicom -D /dev/ttyUSB2”，and then use AT commands to test, such as ”at”，”at+csq”，“at+ccid”，if you get response without error，that means the communication is OK.
- (4) Q: How to install libqmi?
- A: Download from here: http://www.linuxfromscratch.org/blfs/view/cvs/general/libqmi.html 1 ; then make and make install.
- If you meet this:
- you need to install libgudev-1.0-dev， then make and make install again.
- (5) Q：How to use qmi-wwan？
- A：There is a very easy way to use，I’ve put quectel-CM in home path of root，just execute “./quectel-CM &”，then execute “dhclient wwan0”，now you have finished the configurations.
- (6) Q：How to use GPS？
- A：BPI-4G module supports GPS and BeiDou，execute “minicom -D /dev/ttyUSB2”，then input AT commands like this：
- if you want to use BeiDou，just input AT commands like this：
- (7) Here are kernel configurations and driver patch for kernel 4.14.
- (8) Support areas:
- EC25-E support: EMEA/Thailand/India/South Korea
- EC25-AU support: Australia
- EC25-V/-A support：North America
- (9) Openwrt Supported:
- A. Clone the source code from this link : BPI-R2 OpenWrt(LEDE) Souce code : 2018-04-11
- B. Add qmi-wwan driver to this project :
- Execute “./scripts/feeds/ install minicom” to install minicom to openwrt project
- Execute “./scripts/feeds/ install python” to install python to openwrt project
- Execute “make menuconfig”
- Add minicom “Utilities —> Terminal —> minicom”
- Add python “Languages —> Python”
- Add driver “Network —> wwan …Genetic OpenWrt 3G/4G proto handler”
- Add "Kernel modules —> USB Support —>
- kmod-usb-core
- kmod-usb-net —> kmod-usb-net-qmi-wwan
- kmod-usb-ohci
- kmod-usb-serial —> kmod-usb-serial-option , kmod-usb-serial-wwan
- kmod-usb-uhci
- kmod-usb2-*
- Use these source files to replace your openwrt project source files (“build_dir/target-arm_cortex-a7+neon-vfpv4_musl_eabi/linux-mediatek_32/linux-4.9.44/drivers/usb(or net)/…”) :
- C. Image & Stuff Link :
- D. Cross-Compile quectel-CM
- Copy “quectel-CM” to Linux host PC，and change “Makefile” under the “quectel-CM”，change tools like this：The tools are under openwrt project，you can find them according to the following picture.
- If ping Domain name fail，add “nameserver 8.8.8.8” to /etc/resolv.conf
- D. Cross-Compile quectel-CM
- (10) If you use mPCIE interface 4G module to connect R2 by 14 pin header，use these cmds to enable 4G module，after you did these steps，USB0 port will be disable.
- cd /sys/class/gpio/
- echo 266 > export 【# 266(gpio_offset) = 232(base) + 34(GPIO_34)】
- cd gpio266/
- echo out > direction
- echo 1 > value
