I am using XB24-Z7 xBees. I have a one configured as a XB24-ZB Zigbee Router API version version 23A7 and the other configured as XB24-ZB Zigbee coordinator API 21A7. The coordinator blinks the assoc led correctly. Router has LEDs on pin 13 and pin 15. When power via USD both LEDs are on for ~5 seconds, off for ~3 seconds, both blink, both off for ~5, both on for 3 the latter 2 repeats a couple of times then maybe the assoc led blinks correctly for about 3 seconds then both LEDs blink fast (maybe 2 - 3 blinks per second). If left both may stop blinking the assoc led will blink correctly about 3 times then both blink fast.
Cannot connect to the router with X_CTU when both leds are blinking fast. If reset then X-CTU connects.
Any ideas why the router behaves this way?
