Z-STACK GPRS gateway
4.3
I wrote last year, a small project. CC2530+SIM900a achieve the GPRS gateway. To send and receive GPRS data, send and receive text messages. Performance, through GPRS to connect to the server every 30 seconds to send, receiving a 100-byte packets, running day and night there should be no problem.
