RF24 Smart Home Protocol.<\/p>\n
Is a library to let you connect your Arduino (atmega), Teensy (arm) and Raspberry using wifi module NRF24L01+. This library uses Maniacbug RF24 Library<\/a> and add a new layer to it allowing easy communication between many nodes (up to 250). This let user to create a network of any stuff and move then to Internet of Things if Master is connected to internet.<\/p>\n THIS IS UNDER DEVELOPMENT!<\/strong><\/p>\n Goals:<\/strong><\/p>\n Provides an easy to use Network Library for NRF24L01+.<\/p>\n Dependencies:<\/strong><\/p>\n RF24 Library (Arduino) – librf24\/arduino\/ – https:\/\/github.com\/maniacbug\/RF24<\/a> How this library works: <\/strong> Channel 0 is for protocol communication Master station is responsible to ID\/Parent\/Channels distribution (every network must have one) How to use it:<\/strong><\/p>\n Setup your NRF24L01+ and make sure they are working with RF24 Library and their examples. (Guarantee everything is wired correctly) Basic example of communication:<\/strong><\/p>\n Master ON listening on Protocol Channel
\nRF24 Library (Teensy) – librf24\/teensy\/ –

\nThe NRF24L01+ module can listen up to 6 channels. First channel can be 0x7878787878 for example all other channels must be in the same range for example 0xABABABABYY. More information about this you can get on NRF24L01+ datasheet. Channels:<\/p>\n
\nChannel 1 is for parent communication
\nChannel 2-5 is for child communication<\/p>\n
\nStations are peers connected to the Network<\/p>\n
\nCreate a MASTER station
\nCreate less then 250 regular stations
\nJust connect one STATION by time (1 minute to stabilish connection – This is a huge secure factor)<\/p>\n
\nChild connects without an ID – SENDS WHO_LISTEN (Every station that listen to it, will send a message I_LISTEN)
\nMaster sends I_LISTEN
\nChild keep track of 5 nodes that he can talk to. If station receives more then 5 I_LISTEN it will preserve the smaller level ones (So it keeps near MASTER station)
\nChild send ASK_CONFIG
\nMaster reply with SET_CONFIG sending ID, PARENT, LEVEL and other informations
\nIf a child can’t communicate directly to MASTER who can listen to him will forward the ASK_CONFIG (and the SET_CONFIG later)<\/p>\n
