3. WIFI SETUP QUICK START GUIDE
3.1. Software/Set-up Requirements
The following Drivers must be installed:
- Android SDK platform on a Windows machine:
•Go to: http://developer.android.com/sdk/win-usb.html
Follow the instructions for installing the SDK (Select SDK only, no need for ADT
bundles).
•Right-click “My Computer”, select Properties→Advanced→Environment Variables,
and set the path to include the c:\android-sdk-windows\tools directory.
The path must point to directory with fastboot.exe file in it.
For example -> C:\Program Files\Android\android-sdk\platform-tools
•Navigate to the %USERPROFILE%\.android directory (simply copy this line into the
file browser: %USERPROFILE%\.android).
•In the %USERPROFILE%\.android directory, create/edit the adb_usb.ini file. If the file
already exists, it will contain a DO NOT EDIT message. Disregard this message and
edit the file anyway. To edit, add a line containing 0x1bc7 to the end of the file.
The file contents should look like the below:
# ANDROID 3RD PARTY USB VENDOR ID LIST -- DO NOT EDIT.
# USE 'android update adb' TO GENERATE.
# 1 USB VENDOR ID PER LINE: 0x1bc7
- USB drivers on a Windows machine can be downloaded from:
http://www.telit.com/evkevb-drivers/
3.2. Commands example
1) Open Command prompt (cmd.exe), and execute ‘adb shell’ command.
2) Line marking will change to / # , You can proceed to next step
The following steps are run from within this shell, as is.
1) Type QCMAP_CLI, select the following options:
a. type 30 (Enable/Disable Mobile AP) –1: Enable
b. type 31 (Enable/Disable WLAN) –1: Enable
c. type 32 (Connect/Disconnect Backhaul)
I. Backhaul State(1-Connect/0-Disconnect): 1
II. Call Type (1-IPV4; 2-IPV6): 1
3.3. WLAN - User guide
Please see Telit AT Commands reference manual (document number 80407ST10116A) for details
on WLAN available commands.
