When a device is subscribed to a feed, it takes note of any changes that occur there. A feed is basically just a list of data. When a value is added to the feed, any devices that are subscribed to the feed notice. Also if you don't understand what a feed is or what it means to be subscribed to one, then you probably wont be able to help with this question. | |

If not, then the answer is probably "No." Certainly, the cellular module will not be able to keep a TCP/IP connection live while it's in sleep mode. That would shock the heck out of me if it could do that. | |
