RF24Gateway - TCP/IP over RF24Network 0.1b
TMRh20 - Pushing the practical limits of RF24 modules
RF24Gateway is a library style replacement for the standalone RF24toTUN application, used with RF24Ethernet.
In addition to passing TCP/IP payloads to a network interface, RF24Gateway also allows users to send and receive standard RF24Network payloads.
This allows users to deploy and manage hybrid networks, consisting of nodes communicating via TCP/IP and RF24Network Messages
See http://tmrh20.github.io/RF24 for installation instructions using the installer, or clone the RF24 libs and run 'make install' for each one.
After running the installer, RF24Gateway will be installed at rf24libs/RF24Gateway. Examples are included for operating the gateway as well as client scripts & programs to control nodes via http requests.
Note: RF24Gateway is tested with and defaults to using RF24Mesh. Sensor nodes must also use RF24Mesh or be statically assigned within RF24Mesh.
RF24Gateway is relatively simple in design, and uses the Universal TUN/TAP driver for Linux
Data incoming from the RF24 communication stack (designated as external data) is passed to the interface without modification. Conversely, incoming TCP/IP or other data received on the TUN/TAP interface is passed directly into the radio network and designated as external data.
Linux devices running RF24Gateway can establish network links using the built-in TCP/IP stack, and users can include Arduino/AVR devices or additional RPi devices to automatically extend the wireless range.
Arduino/AVR devices, etc must utilize a software IP stack such as uIP.
