We want to move from XTend to XBee Pro 900HP but have a couple of sticking points.
In our application we have one base station but several data loggers (all point to point). Each logger has an address but the base station always has the same address (in our case 22). This makes it easy to swap base stations.
For Xtend, DT was set at 22 in all the loggers and MY was set at 22 in the base station. When the base station wanted to talk to a specific logger it would set the appropriate DT and then talk to a specific logger.
If an alarm condition occurred on the logger, an unsolicited message would be sent out to the base station at a DT of 22.
How would I set up the XBEE to best handle this situation?
