It is also possible to use a Driver on its own, without a Manager, although this only allows unaddressed, unreliable transport via the Driver's facilities. Thereafter the facilities of the Manager can be used to send and receive messages. The programmer is required to instantiate a Driver and a Manager, and to initialise the Manager. Managers provide high level message sending and receiving facilities for a range of different requirements.Įvery RadioHead program will have an instance of a Driver to provide access to the data radio or transport, and usually a Manager that uses that driver to send and receive messages for the application.Drivers provide low level access to a range of different packet radios and other packetized message transports.RadioHead consists of 2 main sets of classes: Drivers and Managers. If you are a beginner, you will need to spend some time gaining knowledge in these areas first. It may not be an appropriate project for beginners. Before asking a question or reporting a bug, please readĬaution: Developing this type of software and using data radios successfully is challenging and requires a substantial knowledge base in software and radio and data transmission technologies and theory.

The version of the package that this documentation refers to can be downloaded from You can find the latest version of the documentation at It provides a complete object-oriented library for sending and receiving packetized messages via a variety of common data radios and other transports on a range of embedded microprocessors. This is the RadioHead Packet Radio library for embedded microprocessors.
