After a few projects with Arduino's, I would love to get my feet wet with JeeNode's. The low-power wireless properties are very attractive to setup a WSN around the house.
However, I already have an arduino with an ethernet-shield and an xbee shield attached. I am not too familiar (yet!) with protocols like I2C and SPI, etc, and I have a bit of trouble figuring out if it would be possible to at the new RFM12B board to the existing setup. If possible, that would enable my gateway-unit to be extended with a communication option for JeeNodes.
I use the gateway unit currently to receive Xbee data and post it to a server online.
The Xbee shield used D0 and D1 (serial tx,rx) ports, and the ethernetshield uses pins also in use by the rfm12b board (D10-D13). Would it be possible to add the RFM12B board as well and still use the xbee and ethernet capabilities?
Kind regards, Arno Jansen
