BH (Broadcast Hops)
The maximum transmission hops for broadcast data transmissions. This will not affect Point-to-
Multipoint transmissions (TO = 40).
If you set BH greater than NH, the device uses the value of NH.
Parameter range
0 - 0x20
Default
0
NH (Network Hops)
The maximum number of hops expected to be seen in a network route. This value does not limit the
number of hops allowed, but it is used to calculate timeouts waiting for network acknowledgments.
Parameter range
1 - 0x20 (1 - 32 hops)
Default
7
MR (Mesh Unicast Retries)
Set or read the maximum number of network packet delivery attempts. If MR is non-zero, the packets
a device sends request a network acknowledgment, and can be resent up to MR+1 times if the device
does not receive an acknowledgment.
Changing this value dramatically changes how long a route request takes.
We recommend that you set this value to 1.
Parameter range
0 - 7 mesh unicast retries
