I have two XBee ZigBees (S2C) and could connect to them with XTCU through an Arduino Uno from which I have removed the 328P chip. I could change parameters and do a range test and everything was working perfectly. Then, I stopped working with for them a few hours and when I came back, I couldn't connect to one of them (but I can with the second pair, just like before). However, connecting to the working one and powering up the "faulty" one, I can perfectly complete a range test. What can I do?
**Also, it seems to me that I can't reset them. I tried shorting pin 5 to ground but the prompt window never closed on its own.
