Actually i want to interface digi's Xbee module with pic 16f877 microcontroller.I know that i can communicate with uc with the help of at commands.
My doubt is that how to recognise data's when xbee receives data and send to microcontroller.I came to know that it will be a packet consist of destination addr and node identifier. How we can extract the right information from that packet.
it describes entering AT mode using "+++" and leaving it to return to transparent mode etc.
In practice I used API mode as that gives one full control of the device allowing setting addresses, cluster ID, etc. but is much more complex requiring one to create frames containing the required information.
