HP
Hopping Channel. Set/Read the channel
hopping sequence. Nodes must have the
same hopping sequence to communicate.
0 - 9 Networking 1 0
ID
Network Address. Set/Read the user
network address. Nodes must have the same
network address to communicate.
0x10 - 0x7FFF Networking 2 0x3332
NH
Network Hops. Set/Read the maximum
number of hops expected in a network route.
This value doesn't limit the number of
hops
allowed, but it is used to calculate timeouts
waiting for network acknowledgements.
0 – 0xFF
[Max number of hops]
Networking 2 7
NN
Network Delay Slots. Set/Read the
maximum random number of network delay
slots before re-broadcasting a network packet.
One network delay slot is approximately
168ms.
0 – 0x10 Networking 2 3
NQ
Network Route Requests. Set/Read the
maximum number of route discovery retries
allowed to find a path to the destination node.
If NQ = 0, a route request will only be sent
once.
0 – 0x0A Networking 2 3
NR
Network Retries. Set/Read the maximum
number of network packet delivery atte
mpts. If
NR > 0, packets sent will request a network
ACK and can be resent up to NR+1 times if no
ACKs are received.
0 – 0xFF Networking 2 1
