Note:
The frames exchanged between the master and the slave have the following configura-
tion:
From the master to the slave, N= 1. The message is a request for information.
From the slave to the master, N = 5. The five bytes of this message include light level
information (coded on 10 bits), level of RSSI, etc .
When you switch on the development kit, a splash screen welcomes you:
Note:
Press the button. The following screen appears:
The blinking black cursor indicates that you can make a selection by turning the rotary
switch on the side of the development kit unit.

This very simple protocol does not rely on any specific or optimized way to exchange
data packets. On a power consumption basis for instance, the demo is not efficient. It
does, however, have the advantage of being relatively robust, hence the probability of
losing any messages is reduced.
The frequency band must of course be selected in accordance with the RF module
plugged into your development kit.
