Hello i know this topic been talked about before and a lot of it i don't understand. But I will try to ask my question. Is it possible to do a arduino gsm with router. So i can connect multiple arduino With Ethernet shields on them and have that data go to the net. So if i type a ip address and port i can see any the data coming from that arduino. Okay yes i can get a Hope spot and and connect it to my router and do the same thing. But i would like to control the gsm to turn it on and off if i need to and I'm adding Bluetooth to i as well. Just trying to figure this out as i go along. Can someone please help me out on this?
