Hi, I am using several series 1 Xbee modules (XB24-AWI). However, two of them doesnt seem to work. For the first one, It once worked but has suddenly become defective. I am unsure of the cause as it has always been connected via a linear voltage regulator board (https://www.sparkfun.com/products/11373). It is currently unable to receive or send signals but previously worked fine. When I connected it to my computer and attempt troubleshooting with XCTU, a dialog notified me of action required to reset the XBee. Thus, I used recovery mode in the XCTU software to reset the firmware. However, the problem still persists after resetting the firmware (802.1) to the latest one, and XCTU still detects an issue with the Xbee module and continues to prompt me to reset the module. I have tried resetting it for several times already. Please advise me on this issue.
Fot the second defective Xbee module. When I connect the power supply to the Xbee either via a USB adapter board or a regulator board, both boards appear to fail in their power supply, as indicated by the fading red LED light and the Xbee does not work.
Please advise on how I can address the issues in both Xbees series 1 modules.
