NOTE: This is under development! A lot of stuff needs to be fixed.
Goals:
- Provides an easy to use Network Library for NRF24L01+.
Dependencies:
- RF24 Library (Arduino) - librf24/arduino/ - https://github.com/maniacbug/RF24
- RF24 Library (Teensy) - librf24/teensy/ -
- RF24 Library (RPi) - librf24/rpi/ - https://github.com/gnulnulf/RF24
How this library works: The 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:
- Channel 0 is for protocol communication
- Channel 1 is for parent communication
- Channel 2-5 is for child communication
How to use it:
- Setup your NRF24L01+ and make sure they are working with RF24 Library and their examples. (Guarantee everything is wired correctly)
- Create a MASTER station
- Create less then 250 regular stations
- Just connect one STATION by time (1 minute to stabilish connection - This is a huge secure factor)
Basic example of communication:
- Master ON listening on Protocol Channel
- Child connects without an ID - SENDS WHO_LISTEN (Every station that listen to it, will send a message I_LISTEN)
- Master sends I_LISTEN
- Child 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)
- Child send ASK_CONFIG
- Master reply with SET_CONFIG sending ID, PARENT, LEVEL and other informations
- If a child can't communicate directly to MASTER who can listen to him will forward the ASK_CONFIG (and the SET_CONFIG later)
TODO:
- Interrupt driven read
