Basic RF communication using the talk demonstration application

Once the talk application has been loaded on the kit's board, different RF communication
scenarios can be targeted as described in the table below.

1 When pressing a button on the application board, LED D1 is turned on, indicating a packet
is going to be sent.
2 When pressing a button on the application board, if something is wrong with the current RF
communication (packet transmission failed or no acknowledgment received from the USB
dongle), the application board LEDs D1 and D3 start blinking for few seconds.
For setting a "chat communication", it is requested to setup a serial communication channel
on both kit's boards by following the steps described in
application serial communication
Once the serial communication channels of the kit's boards are correctly configured, the two
talk demonstration applications can communicate by typing the "chat text" on the
corresponding HyperTerminal.
The above example application shows how an RS-232 cable connection between two
devices can be replaced with a wireless system using STM32W108xx microcontrollers.
