I am new to XBee and looking to start work on a project and trying to figure out the best approach. I am trying to build a network of environmental sensors using Raspberry Pi. The sensor nodes will be solar powered, taking environmental readings every ten or fifteen minutes and passing the recorded data to the other nodes. To minimize power consumption I was considering using the Series 1 with DigiMesh firmware in order to make use of their sleep settings. Please let me know if this approach sounds reasonable or if there might be a better alternative. And if this is the best approach please point me toward any helpful tutorials. I have been reading through Faludi's Wireless Sensor Networks book but it seems to focus mainly on ZigBee and I'm not sure how similar or different the DigiMesh programming would be.
