==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 " 
::[[File:Usb_4g_8.PNG]]
::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:
::[[File:Usb_4g_9.PNG]]
::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：
