Parameter range
1 - 5
Default
3
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.
We recommend that you set this value to
1
.
If you set this parameter to
0
, it disables network ACKs. Initially, the device can find routes, but a
route will never be repaired if it fails.
