It is now time to establish a communication between:
+
* a '''Data Emitter''' (CanSat) made with a raspberry-Pico + RFM69HCW-433MHz.
+
* a '''Data Receiver''' (Base Station) made with the second RFM69HCW coupled to another Pico microcontroler.
+
+
As the kit contains only one micro controller (the Feather M0 Express), we will use the very common '''Arduino UNO''' (not included) as micro controller for the '''Data Receiver'''.
+
+
In this simple example:
+
# The '''Data Emitter''' will send a message and wait 500ms for a response.
+
# The '''Data Receiver''' will receive the message.
