1. SDK enable 3G, please refer SDK(SDK4100) (11.40) p.141~p.145

2. 3G 功能在 WAN 中, 即 Static IP, DHCP, PPPoE, L2TP, PPTP, 3G 同時僅能選一項功能

3. 選 3G 時, 有指定 dongle 型號及自動偵測

4. 連線參數:

   APN: Internet
   Dial Number: *99#

重點程式:

• internet.c
• internet.sh
• autoconn3G.sh
• 3g.sh
• usb_modeswitch

1. wan.asp 會先 submit 到 /goform/setWan

source code: source\user\goahead\src\internet.c

/* goform/setWan */
static void setWan(webs_t wp, char_t *path, char_t *query)
{
...
#ifdef CONFIG_USER_3G
	else if (!strncmp(ctype, "3G", 3)) {
		//usb3g_mode = websGetVar(wp, T("OPMode3G"), T(""));
		usb3g_dev = websGetVar(wp, T("Dev3G"), T(""));
		usb3g_apn = websGetVar(wp, T("APN3G"), T(""));
		usb3g_pin = websGetVar(wp, T("PIN3G"), T(""));
		usb3g_dial = websGetVar(wp, T("Dial3G"), T(""));
		usb3g_user = websGetVar(wp, T("User3G"), T(""));
		usb3g_pass = websGetVar(wp, T("Password3G"), T(""));
 
		//nvram_bufset(RT2860_NVRAM, "wan_3g_opmode", usb3g_mode);
		nvram_bufset(RT2860_NVRAM, "wan_3g_dev", usb3g_dev);
		nvram_bufset(RT2860_NVRAM, "wan_3g_apn", usb3g_apn);
		nvram_bufset(RT2860_NVRAM, "wan_3g_pin", usb3g_pin);
		nvram_bufset(RT2860_NVRAM, "wan_3g_dial", usb3g_dial);
		nvram_bufset(RT2860_NVRAM, "wan_3g_user", usb3g_user);
		nvram_bufset(RT2860_NVRAM, "wan_3g_pass", usb3g_pass);
		nvram_bufset(RT2860_NVRAM, "wanConnectionMode", ctype);
	}
#endif
.
.
.
initInternet();
.
.
.
#ifdef CONFIG_USER_3G
	else if (!strncmp(ctype, "3G", 3)) {
		websWrite(wp, T("3G device: %s<br>\n"), usb3g_dev);
		websWrite(wp, T("APN: %s<br>\n"), usb3g_apn);
		websWrite(wp, T("PIN: %s<br>\n"), usb3g_pin);
		websWrite(wp, T("Dial Number: %s<br>\n"), usb3g_dial);
		websWrite(wp, T("Username: %s<br>\n"), usb3g_user);
		websWrite(wp, T("Password: %s<br>\n"), usb3g_pass);
	}
#endif
}

2. 以上程式會執行 internet.sh, 而internet.sh 會執行 autoconn3G.sh

3. autoconn3G.sh 將從系統 USB 裝置中, 與支援列表中找出對應的 dongle, 對將型號傳給 3g.sh, 由3g.sh 將dongle 轉成 modem 後連線.

4. 3g.sh 將依型號, 指定 conf file 轉換 USB to Modem

.
.
.
#change 3G dongle state to modem
if [ "$dev" = "MU-Q101" ]; then
        usb_modeswitch -c /etc_ro/usb/usb_modeswitch_MU-Q101.conf
elif [ "$dev" = "HUAWEI-E169" ]; then
        usb_modeswitch -c /etc_ro/usb/usb_modeswitch_HUAWEI-E169.conf
elif [ "$dev" = "HUAWEI-E220" ]; then
        usb_modeswitch -c /etc_ro/usb/usb_modeswitch_HUAWEI-E220.conf
elif [ "$dev" = "BandLuxe-C270" ]; then
	sdparm --command=eject /dev/sr0
	sdparm --command=eject /dev/sg0

	usb_modeswitch -c /etc_ro/usb/usb_modeswitch_MobilePeak-Titan.conf

	usb_modeswitch -c /etc_ro/usb/usb_modeswitch_DATANG-M5731.conf
#else
        #other supported devcies
fi
.
.
.

5. usb_modeswitch conf file list, 可以從 source\user\usb_modeswitch-0.9.5\usb_modeswitch.conf 找出, 並寫成一支conf file.

6. 指定modem的port, 並撥號連線

.

#create ppp call script for 3G connection
if [ "$dev" = "MU-Q101" ]; then
        modem_f=ttyUSB0

.
.
if [ "$dev" != "OPTION-ICON225" ]; then
	config-3g-ppp.sh -p $pass -u $user -m $modem_f -c Generic_conn.scr -d Generic_disconn.scr
	pppd call 3g

	else	
		echo "APN=internet" > /etc/conninfo.ini

	if [ "$pin" != "" ]; then	
		echo "PIN=$pin" >> /etc/conninfo.ini

	hso_connect.sh up

.

1. 由 cat /proc/bus/usb/devices 或 由 usb_modeswitch.conf 找出其 Dongle 的 VID/PID
2. 將其 VID/PID 加入 autoconn3G.sh

   SUPPORT_3G="12D1:1001:HUAWEI-E169
   	    12D1:1003:HUAWEI-E220
   	    0408:EA02:MU-Q101

   	    1A8D:1000:BandLuxe-C270
   	    1A8D:1009:BandLuxe-C270"	

3. 及3g.sh

   #change 3G dongle state to modem
   if [ "$dev" = "MU-Q101" ]; then
           usb_modeswitch -c /etc_ro/usb/usb_modeswitch_MU-Q101.conf
   elif [ "$dev" = "HUAWEI-E169" ]; then
           usb_modeswitch -c /etc_ro/usb/usb_modeswitch_HUAWEI-E169.conf
   elif [ "$dev" = "HUAWEI-E220" ]; then
           usb_modeswitch -c /etc_ro/usb/usb_modeswitch_HUAWEI-E220.conf
   elif [ "$dev" = "BandLuxe-C270" ]; then
   	sdparm --command=eject /dev/sr0
   	sdparm --command=eject /dev/sg0
   elif [ "$dev" = "MobilePeak-Titan" ]; then
   	usb_modeswitch -c /etc_ro/usb/usb_modeswitch_MobilePeak-Titan.conf
   elif [ "$dev" = "OPTION-ICON225" ]; then
   	usb_modeswitch -c /etc_ro/usb/usb_modeswitch_OPTION-ICON225.conf
   elif [ "$dev" = "DATANG-M5731" ]; then
   	usb_modeswitch -c /etc_ro/usb/usb_modeswitch_DATANG-M5731.conf
   #else
           #other supported devcies
   fi
   .
   .
   .
   #create ppp call script for 3G connection
   if [ "$dev" = "MU-Q101" ]; then
           modem_f=ttyUSB0
   elif [ "$dev" = "HUAWEI-E169" ]; then
           modem_f=ttyUSB0
   elif [ "$dev" = "HUAWEI-E220" ]; then
           modem_f=ttyUSB0
   elif [ "$dev" = "BandLuxe-C270" ]; then
           modem_f=ttyUSB0
   elif [ "$dev" = "MobilePeak-Titan" ]; then
           modem_f=ttyUSB0
   elif [ "$dev" = "DATANG-M5731" ]; then
           modem_f=ttyUSB0
   else
           #other supported devcies
           modem_f=ttyUSB0
   fi

4. 再產生一份 conf file 例:usb_modeswitch_HUAWEI-E220.conf, 放入 source\user\usb_modeswitch-0.9.5\conf
5. 連線時, 選自動偵測即可.
