Discovery quit working at various times for obvious reasons. At one point I set it back to my old settings and discovery didn't work. The usb access to the chip did everything fine except discovery. I tried everything. I restored firmware, did a recovery, etc. I assumed my radio in the chip died.
I put in a xbee chip from one of my routers and verified the network settings matched the coordinator. I then flashed the coordinator firmware onto that chip with the same settings. Nothing changed with the new chip.
So I know the chip is good, and my usb connection is good, but discovery doesn't work with any of the old routers that I haven't touched. The only thing left that could be bad on the explorer is the board itself which makes no sense.
Does anyone have any ideas what could kill discovery? I'll try anything.
