路由器上调试3G拨号
建立 3G拨号镜像的步骤
1. 配置内核，需要添加
nfs 方便调试
usbserial 加载驱动
2. 配置其他选项： vendor
3g 添加拨号工具和脚本
最好给busybox 加上 netcat 方便调试了。
3. 修改配置文件,添加对额外模块的支持，故我们定义如下
sbin/3g.sh
etc_ro/web/internet/wan.asp
920 <option value="http://www.mamicode.com/MU-Q101" id="MU-Q101">NU MU-Q101</option>
+ <option value="http://www.mamicode.com/MC8630" id="MC8630">ZTE MC8630</option>
921 <option value="http://www.mamicode.com/HUAWEI-E169" id="E169">HUAWEI E169</option>
elif [ "$dev" = "HUAWEI-E169" ]; then
usb_modeswitch -c /etc_ro/usb/usb_modeswitch_HUAWEI-E169.conf
+elif [ "$dev" = "MC8630" ]; then
+ echo "we use MC8630, no need usb_modeswitch"
elif [ "$dev" = "HUAWEI-E169" ]; then
vend_id="0x12d1"
prod_id="0x1001"
+elif [ "$dev" = "MC8630" ]; then
+ vend_id="0x19d2"
+ prod_id="0xfffe"
-insmod usbserial vendor=$vend_id product=$prod_id
+insmod /etc_ro/usbserial.ko vendor=$vend_id product=$prod_id
if [ "$dev" != "OPTION-ICON225" ]; then
- config-3g-ppp.sh -p pass -u user -m $modem_f -c Generic_conn.scr -d Generic_disconn.scr
+ config-3g-ppp.sh -p CARD -u CARD -b 115200 -m $modem_f -c my_conn.scr -d Generic_disconn.sc
pppd call 3g
4. 编译 my_conn.scr
-send "ATD*99#^m"
+send "ATD#777^m"
- set com 115200n81
+set com 310000n81
- send "AT+CFUN=1;+CGDCONT=1,\"IP\",\"Internet\"^m"
- waitfor 10 "OK","ERR","ERROR"
try remeber{
vendor=0x19d2 product=0xfffe
+ config-3g-ppp.sh -p CARD -u CARD -b 460800 -m $modem_f -c Generic_conn.scr -d Generic_disconn.sc
}
4. 编译镜像， 并加载， 在web界面选择3G模块
5.
=================================================================================
6. 调试记录
其它可能的初始化和AT配置(从官方截取的配置)
Init2 = ATZ
Init3 = ATQ0 V1 E1 S0=0 &C1 &D2 +F>ISDN = 0
Auto Reconnect = off
crtscts
lock
asyncmap 20A0000
kdebug 4
-detach
lcp-echo-failure 4
lcp-echo-interval 30
ipcp-max-failure 30
ipcp-max-configure 30
-ccp
-vj
nvram_get 2860 wan_3g_dev
lan_ip=`nvram_get 2860 lan_ipaddr`
stp_en=`nvram_get 2860 stpEnabled`
nat_en=`nvram_get 2860 natEnabled`
bssidnum=`nvram_get 2860 BssidNum`
radio_off=`nvram_get 2860 RadioOff`
获得flash paramter 中 3G模块的配置信息
# nvram_get 2860 wan_3g_dev
HUAWEI-E169
ralink_init make_wireless_config rt2860 ??? 设置 flash paramter
ralink_init make_wireless_config rt2860
是否这个配置导致 pppd 问题
cat /dev/mtd1 可以打印所有的环境变量， 不过要拷贝后格式化一下再看。
