FAQ

  • (2) Q: What should I do, if you meet this "expect (OK) ^M alarm Failed "
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:

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:

  • (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/
