easy API with a few simple functions for basic usage
127 possible nodes on 256 possible networks
128 bytes max message length
customizable transmit power (8 levels) for low-power transmission control
customizable air-Kbps rate allows fine tuning the transmission reliability vs speed (transmitting slower is more reliable but takes more time which implies more power usage)
Sleep/Wakeup functionality for power saving
Low battery detector with customizable low voltage threshold
Support for targeted ACK instead of broadcasted ACK (possible because of the new source byte in the header)
encryption with XXTEA algorithm by David Wheeler, adapted from http://en.wikipedia.org/wiki/XXTEA
Support for these chips: ATMega8 family (ATmega168, ATMega328) ATMega2560, ATMega1280, ATMega644P, ATTiny84, ATTiny44, ATMega32u4. So far only tested on ATMega 328/P
wireless programming (for more info click here, here and here)
the library needed for wireless programming is now here, install it in your Arduino/libraries folder (WirelessHEX for RFM12B)
Copy the content of this library in the "Arduino/libraries/RFM12B" folder.
To find your Arduino folder go to File>Preferences in the Arduino IDE.
See this tutorial on Arduino libraries.
