I bought 2 light bulbs which should support IEEE 802.15.4 2.4GHz Zigbee communication. Unfortunately the supplier doesn't provide me with any technical documentation about the communication protocol. I have one XBEE S1 802.15.4 ready as coordinator in API mode and I would like to detect those 2 light bulbs as end devices and communicate with them (mainly turn it off and on). I don't know on which channel or PAN ID they operate. I can just assume that the communication is not encrypted. Any idea would be highly appreciated.
