Wireless USB Gateway and the Host Computer Sleep Mode and Power Off

Keywords: USB doesn't work, sensors offline, computer sleep, computer powered off, USB power


Summary:

What happens to a wireless sensor network when a USB wireless gateway and the host computer goes into sleep mode or is powered off.



If the MonnitLink™ wireless gateway is unable to receive transmissions from the sensors due to the PC being off or asleep, the sensors will continue to try and link with the gateway (two times by default). If it is unable to link to the gateway it will enter “link mode” where it will search for another nearby gateway. If no gateway is found, the sensor enters "power save" mode, and will sleep for two hours before entering link mode again, and search for a gateway. This process will continue until the sensors find a gateway to communicate with.


Note: While the gateway is off, no data is being collected and no notifications can be transmitted.
