Similar problem here with firmware 8162, got 0x80 as command status.
I find these module rather buggy...
does "remote address" is as expected?
in my case it shows the same as the node discovered which is odd, here a sample:
7E 00 23
97 01
00 13 A2 00 40 78 8F C4
FF FE
4E 44
80 FF FE
00 13 A2 00 40 78 8F C4
20 00
FF FE 01 00 C1 05 10 1E
C9
