This file is part of the GSM3 communications library for Arduino
|
|||
|
|
-- Multi-transport communications platform
|
|||
|
|
-- Fully asynchronous
|
|||
|
|
-- Includes code for the Arduino-Telefonica GSM/GPRS Shield V1
|
|||
|
|
-- Voice calls
|
|||
|
|
-- SMS
|
|||
|
|
-- TCP/IP connections
|
|||
|
|
-- HTTP basic clients
|
