I’m in the middle of designing my own board with an XBee on it. Eagle gives me a warning that the RESET and RTS pins are unconnected (and yes, they are unconnected). Do I need to connect both to VCC (+3.3V)?
I do understand that pins normally “float” on a lot of devices. On the other hand, the XBee manual says “unused pins should be left disconnected”. Pin 16 (RTS) is apparently equipped with a pullup resistor which is by default enabled, so I’d think that one wouldn’t be a problem. The manual also says “Module includes a 50K Ohm pull-up resistor attached to RESET”, so I’ve assumed I don’t need to mess with that one either. I don’t see any lines going to 3.3V from the RESET pin on the Selmaware boards I’ve been using.
In short, is Eagle just giving me a “heads-up” that I can ignore, or will I find myself with useless boards if I design my own XBee carrier boards with no connection to RESET and RTS? (or need to “green wire” them to make them work?)
