2g gprs

http://wenku.baidu.com/view/acffc7ebf8c75fbfc77db2ec.html

基本情況：

核心需支援ppp協定，也要支援這個usb裝置,

ppp client調用pppd進行撥号,pppd會調用chat程式與遠端的ppp server會話。

tiny6410 e261上網卡撥号流程：

首先配置驅動：

3g裝置驅動支援
Device Drivers  --->
 [*] USB support  --->
 <*>   USB Serial Converter support  --->  
 [*]   USB Generic Serial Driver 
 <*>   USB driver for GSM and CDMA modems   
ppp協定支援
[*] Network device support  --->
<*>   PPP (point-to-point protocol) support 
[*]     PPP multilink support (EXPERIMENTAL) 
[*]     PPP filtering
<*>     PPP support for async serial ports 
<*>     PPP support for sync tty ports
<*>     PPP Deflate compression 
           

假設3g子產品(或上網卡)插在闆子上已經被識别成了/dev/ttyUSBx了，進行pppd撥号的程式如下

1.編譯pppd源碼，将生産的pppd，chat搞到闆子的/usr/sbin下

2.在/etc下建立ppp目錄

3.ppp下建立pap-chat檔案，和peers目錄

[[email protected]]# cat pap-secrets 
cmnet   *       cmnet *
           

4.在peers目錄下建立

wcdma和chat-wcdma-connect和chat-wcdma-disconnect//用于聯通3g的撥号腳本

cdma2000和chat-cdma2000-connect和chat-cdma2000-disconnect//電信3g

tdscdma和chat-tdscdma-connect 和chat-tdscdma-disconnect//移動3g

内容如下：

5.撥号

pppd call wcdma

進入目錄/var/run/，檢視是否産出檔案 ppp0-ok，如果有，則表示已撥号成功，ppp0-ok檔案内會存儲IP位址和DNS。

/etc下建立resolv.conf檔案，将配置設定到的兩個DNS伺服器位址,添加到此檔案中,内容如下：

nameserver 210.22.70.3

nameserver 211.95.1.97

ifconfig有資訊

[[email protected]]# ifconfig 
ppp0      Link encap:Point-to-Point Protocol  
          inet addr:10.45.210.114  P-t-P:10.64.64.64  Mask:255.255.255.255
          UP POINTOPOINT RUNNING NOARP MULTICAST  MTU:1500  Metric:1
          RX packets:9 errors:0 dropped:0 overruns:0 frame:0
          TX packets:9 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:3 
          RX bytes:180 (180.0 B)  TX bytes:216 (216.0 B)
           

6.使用如下指令切斷連接配接

ppp-off 

或 kill -9 pppd程序ID 

如果3g裝置插在闆子上沒有自動出現/dev/ttyUSBx:

使用如下指令将e261由cdrom模式轉換成modem模式，此時會生成/dev/ttyUSB0-5

3g-ppp /etc/3g-modem/12d1.1446.12d1.1001

usb_modeswitch

ndis上網

1.

配置核心生成usbnet.ko (drivers/net/usb/)

Device Drivers  --->     

[*] Network device support  --->      

USB Network Adapters  ---> 

<M> Multi-purpose USB Networking Framework

編譯希姆通廠家7100等子產品的ndis驅動GobiNet,ko

2.

搞到闆子上加載

insmod usbnet.ko 

insmod GobiNet,ko

3.

子產品插在班子上，會出現

/de/qcqmi0

ifconfig -a

有usb0接口出現

4.撥号

ndismanager  /dev/qcqmi0

進入菜單進行撥号

at 原始指令撥号

子產品的撥号需要相關的網絡at指令的支援
