1 Using 4G Module EC20 on FriendlyCore
1.1 Step1：Compile the quectel-CM command line tool on the development board
Compile and install quectel-CM into the /usr/bin/ directory by entering the following command：
git clone https://github.com/friendlyarm/quectel-cm.git cd quectel-cm/ make cp quectel-CM /usr/bin/
1.2 Step2：Add udhcpc script
The quectel-CM tool will call the udhcpc script. we need to create a udhcpc script for it. Please create a new file with the editor you are familiar with. The file name is: / Usr/share/udhcpc/default.script, the content is as follows：
#!/bin/sh # udhcpc script edited by Tim Riker <Tim@Rikers.org> [ -z "$1" ] && echo "Error: should be called from udhcpc" && exit 1 RESOLV_CONF="/etc/resolv.conf" [ -n "$broadcast" ] && BROADCAST="broadcast $broadcast" [ -n "$subnet" ] && NETMASK="netmask $subnet" case "$1" in deconfig) /sbin/ifconfig $interface 0.0.0.0 ;; renew|bound) /sbin/ifconfig $interface $ip $BROADCAST $NETMASK if [ -n "$router" ] ; then echo "deleting routers" while route del default gw 0.0.0.0 dev $interface ; do : done for i in $router ; do route add default gw $i dev $interface done fi echo -n > $RESOLV_CONF [ -n "$domain" ] && echo search $domain >> $RESOLV_CONF for i in $dns ; do echo adding dns $i echo nameserver $i >> $RESOLV_CONF done ;; esac exit 0
Assign executable permissions with the following command：
chmod 755 /usr/share/udhcpc/default.script
1.3 Step3：Start 4G dialing
Start the dialing by entering the following command:
quectel-CM &If the dialing is successful, the screen will output information such as the IP address, as shown below:

1.4 Test 4G connection
Ping a domain name to see if DNS resolution is already working：
root@NanoPC-T4:~# ping www.baidu.com PING www.a.shifen.com (183.232.231.174) 56(84) bytes of data. 64 bytes from 183.232.231.174 (183.232.231.174): icmp_seq=1 ttl=56 time=74.3 ms 64 bytes from 183.232.231.174 (183.232.231.174): icmp_seq=2 ttl=56 time=25.1 ms 64 bytes from 183.232.231.174 (183.232.231.174): icmp_seq=3 ttl=56 time=30.8 ms 64 bytes from 183.232.231.174 (183.232.231.174): icmp_seq=4 ttl=56 time=29.1 ms 64 bytes from 183.232.231.174 (183.232.231.174): icmp_seq=5 ttl=56 time=29.2 ms
