XBee S2C ZigBee: pins 2,3 and 17 won’t act as DIO. I have been working on a project involving XBee S2C… currently have a coordinator module and 2 router modules communicating… a GUI started… I have sunk many many hours into the project making progress:).
I am successfully configuring and manipulating 12 of the 15 available DIO BUT not pins 2,3, and 17. They don’t seem to care what I set them to in XCTU or in my programming code. Anyone know any reasons for these pins not working as DIO (The datasheet says they should be DIO since there are 15 total.) Both router modules in the network are showing pin 2,3, and 17 with the same stubbornness. I have troubleshooted a good deal (multimeter) and changing configuration in XCTU as well as in code.
I need 14 DIO for my project, per XBee router module, and also I’m not sure that XBeeS2C supports port expanders(?)…so these pesky stubborn pins 2,3,and17 are important to my project.
Anyways, anyone know why pins 2,3, and 17 aren’t cooperating as DIO?
