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:
