The xbee has been disconnected before searching for xbees, in this case in scan mode.
It has been on the mesh the day before.
On the other hand there are a few xbees which don’t show up on XCTU, but do receive commands.
There are 83 xbees on the mesh.
Check your preferences in XCTU for the Network. You may not be having the nodes that are no longer on the network still being shown.
thanks for the quick answer.
Well, there are no ghosts.
The client got the numbers mixed up, although I’ve asked a few times, whether he is sure.
