		+	=== Introduction ===
		+
		+	This guide tells how to use 4G module on ROCK Pi 4. 4G modules including SIM7600 and QUECTEL EC20 are tested.
		+
		+	=== Install needed packages ===
		+
		+	The new version (4.4.179) of ROCK Pi 4 Kernel packages are located at Radxa APT testing branches.
		+
		+	Firstly, add Radxa APT source, '''stretch-testing''' or '''bionic-testing''' according to [https://wiki.radxa.com/Rockpi4/radxa-apt Radxa APT]
		+
		+	Secondly, update U-Boot
		+
		+	* ROCK Pi 4A
		+
		+	sudo apt-get install rockpi4a-rk-u-boot-latest
		+
		+	* ROCK Pi 4B
		+
		+	sudo apt-get install rockpi4b-rk-u-boot-latest
		+
		+	Thirdly, update Kernel
		+
		+	sudo apt-get install -y rockchip-overlay
		+	sudo apt-get install -y linux-headers-4.4.179-11-rockchip-g7ebe2c58142e
		+	sudo apt-get install -y linux-image-4.4.179-11-rockchip-g7ebe2c58142e
		+	sudo apt-get install -y linux-firmware-image-4.4.179-11-rockchip-g7ebe2c58142e
		+
		+	Finally, reboot the machine.
		+
		+	=== Test ===
		+
		+	After pluging the 4G Module, some Kernel log would be shown like this.
		+
		+	root@rockpi:~# dmesg -c
		+	[ 30.578257] usb 2-1: new high-speed USB device number 2 using ehci-platform

		+
		+	Also, the device '''/dev/cdc-wdm0''' is created with network interface name '''wwan0'''.
		+
		+	Test commands:
		+
		+	echo Y > /sys/class/net/wwan0/qmi/raw_ip
		+
		+	ip link set dev wwan0 up
		+
		+	qmicli --device=/dev/cdc-wdm0 --device-open-proxy --wds-start-network="ip-type=4,apn=data.tre.se" --client-no-release-cid
		+
		+	udhcpc -q -f -n -i wwan0
		+
		+	Use '''speedtest''' tool
