Tcp Communication A6 Module

If you want to test the tcp communication with the A6 Module you can follow this tutorial (but use the AT commands for the A6) BUT before, make sure the port is open, go in your router and create a  “NAT”, choose the port you want(something like 747), internal and external(the same), for the device choose the internal IP of your computer.

You can check if the port his open with this website:

(You must creat the server before check the port or it will not work!)

Check his channel because he has a lot of things about Gprs/gsm module, they are for the SIM900 but the A6 is close to this module.
