Asynchronous Network
The asynchronous mesh firmware offers a straight forward communication option that allows the user
to quickly transmit and receive data between two or more all nodes. Figure 4-2 depicts this
communication topology. If all the nodes are within range and have compatible parameters,
communication between them will succeed.

Each node can only communicate to other nodes within its RF range. Also, it is mandatory to assign a
different node id to each node for the network to work properly. An example of setting the NODEID of
the modem:
ATS10=5
AT&W
ATZ
It is possible to address data to a remote node. To do so, set the DESTID parameter to be the same as
the node id of the target. For example:
ATS11=6
AT&W
ATZ
Node 1
Node 2
Node 3
Node 0
Node 4
All nodes within range
