c) Configure the connected Thetis-I mini evaluation boards: go to the "CSAP" tab
and set
• the node address to a unique address (for the sink we used 0 in the example,
thus do not use 0 here for the routing node).
• the address of the network to 7.
• the channel of the network to 39.
• the node role to "ROUTER_NODE".
d) Start the radio stack on the "MSAP" tab (see figure
3
).
e) To transmit data from the Wirepas mini evaluation board to the sink enter the data
you want to transmit in the fields of the "DSAP" tab. As destination node address
type "sink".

2.2 Taking into operation - Host controller
To take the mini evaluation board into operation using a host controller, pin header P3 shall
be used.
An external power supply shall be connected to the evaluation board. The power supply op-
tion 2 or 3 from the table
15
shall be used. It is important that the VDD is stable and able to
reliably supply the module’s static and peak current consumption as specified by the module
manual.
The next step is to connect the communication lines of the module to the host controller. The
headers P1, P2 and P3 can be used to connect the module pins to the host.
All details about the UART interface can be found in the Wirepas dual MCU manual [1] and
the Thetis-I manual. A free C implementation of the Wirepas Dual MCU API is available at:
