I'm using an XBee 3.0 with firmware 100B (ZigBee 3.0 TH). I first set the module to API (No Escapes). All other parameters are at their defaults. Then press the network mode button. The module appears in the window.
After pressing the scan button, I get an error dialog:
Error discovering neighbors of xxx
Cannot find the local device xxx address
Remove it from the modules list on the left and add it again
The "xxx" in the dialog matches the MAC of the module.
Removing and adding it back results in the same error.
