How to use FreeRTOS+UDP on SAME70 with 2G/3G GSM Modem(not with ethernet) connected through UART, is there any poratble solution available.
FreeRTOS+UDP is a predecessor of FreeRTOS+TCP.
The latter is a superset of the former: it contains both UDP and TCP, but it has much more.
I'm afraid I don't know much about connectivity through GSM.
A +TCP driver has to do 2 things: send an Ethernet packet, and receive Ethernet packets. I think that GSM will embed these Ethernet packet in a protocol like PPP?
