偶然发现OBi官网上提到如何在OBiTalk上远程设置OBi100 automatic firmware upgrade。今天在两个远程OBi100上都试成了。
这个法子不用下载什么firmware file。任何设备有浏览器（browser）就能搞定。当然firmware URL千万不能写错。

How do I automate upgrades to the most current available firmware?
You may configure your OBi device to periodically check for new firmware updates.
When an update becomes available, the OBi will automatically download and install the update.
Sign-in to OBiTALK and choose your OBi device.
Navigate to and enter the OBi Expert Configuration page for your device.
Go to the System Management -> Auto Provisioning section of the web page.
Modify the Auto Firmware Update parameters as follows:
Set Method = Periodically
Set Interval = a numeric value in seconds. For example, enter 86400 to check on a daily basis.
For OBi1 Series: （this include OBi100, 110)
Set FirmwareURL = http://www.obihai.com/firmware/OBi-latest.fw
For OBi2 and OBi3 Series: (this include OBi200, 202）
Set FirmwareURL = http://www.obihai.com/firmware/OBi2-latest.fw
For OBi5vs Series:
Set FirmwareURL = http://www.obihai.com/firmware/OBi5-latest.fw
For OBi1000 Series:
Set FirmwareURL = http://www.obihai.com/firmware/OBiPhone-latest.fw
Click "Submit" at the bottom of the page.
下面是进入Expert Mode后的图：
注意OBiTALK Settings及Device Default的勾都要去掉。
如是OBi100, FirmwareURL用http://www.obihai.com/firmware/OBi-latest.fw
然后到最下面点“Submit”：
成功更改：
过一会自动升级完成，系统状态显示新firmware
回到Dashboard，见Google Voice显示connected
