6.4 Configuring the Two Wireless Nodes
The following are the steps to configure the nodes:
- The user can connect to any of the last Paired/Connected devices. If connection is through the previous connection details, configure the modules such that one of the nodes, for example, Node A, initiates the connection and the other node, for example, Node B, waits for Node A to initiate the connection by sending the request to join. The LED (green) is still toggling, which indicates the unconnected state of the nodes (see the following figure). For a new connection, refer to step 7.
- At Node A and Node B, press switch S1 to connect
to the previous node.
- The user can now press switch S1 to initiate the
connection from Node A. At Node B, also press switch S1 to wait for a peer
connection request (see the following figure).
- Node A can select one of the MAC_ADDR (MAC addresses) from the Trusted Device List (TDL) to enable sending a connection request to Node B (see the following figure).
- Press switch S1 at Node A to connect to any of
the previously connected peer devices (in this case, Node B).
- An attempt to connect to the selected MAC_ADDR is
done (that is, Node A connecting to Node B) (see the following figure). Upon
successful connection, the toggling LED (green) becomes stable (refer to step 1 of Post Connection). If there are no devices selected in the previous step, Node A
cannot connect to any of the devices from TDL.
- The user can choose whether a factory reset must
be done (see the following figure).
- The module displays its MAC_ADDR, which the user
must make a note of for further selection and configuration (see the following figure).
