BPI-4G LTE module with banana pi
How to use BPI-4G LTE module with BPI-R2
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.
