Raspberry pi hardware watchdog

We run outdoor-devices based on raspberry pi platforms. Those devices are remotely controlled via a web-application that generates the control-commands and sends them via openvpn to the respective Raspberry Pi device.

Due to poor infrastructure, some of the devices must work under 3G/umts conditions. In this case a mobile USB-Surfstick (3G/UMTS) provides the Internet connection.

Unfortunately this solution does not work sufficiently enough for our purposes. For unknown reason the device looses connection and does not come up again - even not with a software reboot. In such cases we must travel to the devices location and plug-off plug-on the power cable to re-initiate the internet connection. This is too nasty and costly.

The scope of this project is to develop an appropriate software running on the ArchLinux RaspberryPi which initiates a reset by interrupting the units power as soon the internet-connection is lost for a given period of time.

We have foreseen to use Yocto-Watchdog's as hardware unit (please see [url removed, login to view] for details.

Hi. That's an interesting project, I also purchased myself this little magic device and playing with it. So, basically we need a simple script which will watch the internet connectivity for x seconds(configurable). Flere

Hi! You don't need any watchdog hardware for your RPBI! I can write suicide script - if device lost connect more than XXX time - it will reboot yourself. Please keep your money and

Hi. How do you check if software reboot does not help? Why I'm asking - you can try to use watchdog daemon (see this link for details [login to view URL] Flere

Hello! I think your goal may be reached by simpler method. Just using two GPIO port of Rpi for controlling power lines of USB port to modem. (via relays or optokeys).... It will be cheaper in hardware, and simpler Flere

Why don't you just use a relay connected to the Raspberry pi instead? Or a relay connected to a delay-turn-on? [login to view URL] Flere
