I have two XBee S2s, and I want to configure them to take digital input (3.3 V) from one XBee and get a digital output from another XBee to control the AC devices.
I have tried many XBee configurations for it, but I don't get the desired output.
How do I get this configuration right?
The Series 1 modules support I/O Line Passing -- a mode where an input on XBee A can trigger an output on XBee B.
In the case of Series 2 modules, you need to have a host processor on one end which can receive input change notifications (see
ATIC) and generate an AT command frame to manually change the output pin to match the input pin's state.
