新版CSL 4G LTE USB手指響Linux用到了, 方法內進

本帖最後由 kennylam777 於 2011-8-18 05:07 編輯

ONLY for those who knows how to configure 3G modem on Linux!

Tested on ZTE MF820 (CSL HongKong ver.) with Ubuntu 11.04
舊版AL621可能都用到, 只係要改改Vendor/Product

usb_modeswitch (由19d2:0166既USB CD-ROM切去19d2:0167 USB Composite device既方法)
==========================
DefaultVendor= 0x19d2
DefaultProduct=0x0166

TargetVendor= 0x19d2
TargetProduct=0x0167

MessageEndpoint=0x01
MessageContent=55534243e856e2892400000080000685000000240000000000000000000000

=====================
After 19d2:0167 shown in lsusb
-------------
sudo modprobe usbserial vendor=0x19d2 product=0x0167
sudo modprobe option
-------------
A gsm modem should be detected now, enjoy~

ZTE AT init command (其他網都未講過LTE Only......)
------------------------------------
AT+ZSNT=0,0,0 (Auto) - Default
AT+ZSNT=1,0,0 GPRS Only
AT+ZSNT=2,0,0 3G Only
AT+ZSNT=0,0,1 GPRS Preferred
AT+ZSNT=0,0,2 3G Preferred

AT+ZSNT=6,0,0 LTE Only (Tested)
AT+ZSNT=0,0,6 LTE Preferred (Not tested yet)

AT+CFUN=1,1 Reset modem(Not tested yet)

AT+CGDCONT: 1,"IP","lte.public","0.0.0.0",0,0 APN setting
呢個係3GPP定既新format: +CGDCONT: <cid>, <PDP_type>, <APN>,<PDP_addr>, <d_comp>, <h_comp>, 少咗一樣都唔得, 唔同以前D 手機有頭三個就pass, 所以用Gnome個modem manager去改APN就會炒, 一係留空佢算

全部嘢都係靠SniffUSB 2.0同MS Portmon去搵出黎, 應該係全球首發既參數, Linux用家有福喇

以上Setting響OpenWRT都用得, 因為OpenWRT都係用usb_modeswitching+usbserial去食3G modem, 即係話而家有一堆有USB port 既router都可以上4G
