I have 2 XBEE pro S1 , one is connected to the arduino uno, the xbees were configured properly and have been working well for over the past 2 months but suddenly the one connected to the arduino has stopped working , I’m using a 3.3v regulator on the xbee and a 2k, 1k voltage divider between arduino and xbee Din , the dout is connected directly to the arduino.All of a sudden the Xbee stops transmitting. I’ve no clue what mistake I made. I tried the recovery options on XCTU and it shows no bootloader found , the ASSO pin of the XBEE USB ADAPTER doesnt flash while the other XBEE is perfectly functioning.
I’ve a competition to take part in tomorrow please help me out .
