It seems that Arduino is TX and RX lines are connected correctly, because you get response to AT commands. Problem is, that sensor node can not connect to EasyIoT server. Possible reasons are: EasyIoT server is not running, server is behind firewall, server IP address is not correct or even bad power supply.
Replied by EasyIoT on topic help plz !!
