I need that all my nodes send messages to the coordinator in one single hop. Any suggestions?
All my nodes are XBee 2mW Series 2.5 Chip Antenna (XB24-BCIT-004 )
Update your modules with the ZB firmware and use the End Device firmware with in ZB to make all modules talk directly to the Coordinator. FYI you are limited on the number of modules that can be associated with the coordinator. In AT mode I believe it is 8 and in API I think it is 10. These numbers are just an estimate.
Thank you very much
