BH (Broadcast Hops)
This command applies to the XBee SX 868 RF Module.
The number of hops for broadcast data transmissions.
Set the value to 0 for the maximum number of hops.
If you set BH greater than NH, the device uses the value of NH.
Parameter range
0 - 0x20
Default
0
NH (Network Hops)
This command applies to the XBee SX 868 RF Module.
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
Default
7
NN (Network Delay Slots)
This command applies to the XBee SX 868 RF Module.
Set or read the maximum random number of network delay slots before rebroadcasting a network
packet.
Parameter range
1 - 5
Default
3
MR (Mesh Unicast Retries)
This command applies to the XBee SX 868 RF Module.
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.
