I am aiming to implement MQTT feature on my Arduino mega 2560 board connected to a GSM/GPRS module. I do not have an Ethernet shield or a Wifly shield. Is it possible to implement this feature with a GSM/GPRS module ? Where can i get the relevant library ?
Ah OK, well for people (like me) who are interested but know nothing about it in detail, Message Queuing Telemetry Transport (MQTT) is a protocol defined by IBM that enables simple, low overhead messaging to be passed around a network and uses publish/subscribe principles for communication. It has been cited as an ideal method for low powered devices (such as arduino) or mobile devices to communicate with a service to get some state information or to publish a device's state. Twitter, Google and other trendy apps use this method already for pushing presence status to a device.
Jonathan Oxer (he of freetronics and SuperHouseTV fame) has indicated he thinks it is the way forward for federated home automation...
To the original poster: I have found the following resources to be interesting to Arduino projects
As the "how to use this forum" link suggests, and I know not everyone reads it, if you are going to ask a question about "help with X" it helps to provide a link to X, rather than make people who are trying to help you do extra research to even get started.
