Going from GSM data, toward GPRS/UMTS ? | Telit Cinterion IoT Developer Community

June 19, 2014 - 4:12pm, 3330 views

Hello My name is Jean-Marc. Sorry if my English is approximative ! I'm wondering how to go from the M2M Data GSM world to the GPRS/UMTS world. --> Imagine a PLC1 sending data to a PLC2, simply through RS232 port, using the GSM data network: just a few AT commands and the phone number of the PLC2 are required, it's very simple. --> The problem is that the GSM data service will be discontinued soon in my country (obsolete) !!! So, how to connect simply PLC1 to PLC2 via 2 RS232 ports ? My understanding of the situation is: PLC1 and PLC2 have to be connected to (e.g.) MC55iT or BGS5T, including a TCP stack. PLC2 must be a TCP socket server, so as PLC1 can call PLC2 through a socket client. After connection, the data will be sent/received easily on the RS232 ports, is this right ? What will be necessary ? A fix IP or is it possible to use a DynDNS service ? Is there any tutorial ? My knowledge in this is pretty limited, so I need some guidelines to undertand and then proceed to my design. Many thx for any helping !
