Is it possible to use the XBee (X2B) security to prevent join? It doesn't seem to allow this - data comm is blocked, but not (from the remote router's view point) being joined to a coordinator with security enabled.
I am trying to salvage some nodes sealed inside cases. Unfortunately, things like PAN and SC are hard-coded in FW, so I have 2 sets of equipment which 'mix' on 2 different Digi-X2D gway.
I had thought I could use security, as the sealed nodes allow me to change EE and KY remotely, however what I am seeing:
In coordinator (in Digi-X2D), it set EE=1 and KY={some key}. Great - just like example in PDF doc.
In the routers, which have EE=0 ... they STILL happily join the coordinator, merrily blinking their LED.
However, the coordinator does NOT see them; they don't show up on the GWay's xbee list.
If I add another test Router API node, it also gets into this happily-but-sad mode. XCTU allows me to show the network, with the Digi-X2D as coordinator and all the dumb-happy routers who think they belong to this broken network.
Is there a setting in the Xbee coordinator (all are the 0x2?A7 FW) which would prevent it from offering joining to any node with security disabled (EE=0)?
