The following wiring will prepare the "Receiver Station" for the mission 1. From the "RFM69HCW Testing" section, we will use an Arduino UNO and RFM69HCW module to '''redirect the Radio Messages to the serial port'''.

Then press the "upload" button.

== Capturing data to file ==
Having data available in the Arduino Serial Monitor is great... but capturing it without Arduino would be even better.
=== Putty ===
The putty software (available on Windows, Mac, Linux) can be also be used to connect to the Arduino Serial Port interface
Here how it should be configured to capture the data.
[[Fichier:ENG-CANSAT-MISSION1-RECEIVE-30.png|360px]]
Putty also offers some logging capability that may be useful.
=== Linux command ===
If you are addict to Linux or Raspberry-Pi board then you can easily view and capture the data with the following commnands.
cat /dev/ttyACM0 > output.dat
This command will redirect the content of the USB port to a file named {{fname|output.dat}} .
=== With Python ===
The following Python script will capture a serial port (see {{fname|baud_rate}} variable) and write the content to a file (see {{fname|write_to_file_path}} variable).
The content of the file is reset when the script is started.
{{ambox-stop|text=Openning the Serial Port will issue the automatic Reset feature of the Arduino board.}}
<syntaxhighlight lang="python">
import serial
serial_port = '/dev/ttyACM0';
# depend on Serial.begin(baud_rate) in Arduino
baud_rate = 115200;
write_to_file_path = "output.txt";
output_file = open(write_to_file_path, "w+")
ser = serial.Serial(serial_port, baud_rate)
try:
while True:
line = ser.readline()
line = line.encode("utf-8") #ser.readline returns a binary, convert to string
print(line)
output_file.write(line)
except KeyboardInterrupt:
print( 'User abord' )
output_file.close()
ser.close()
</syntaxhighlight>
=== Other options ===
You may find many other capture methods from Internet:
* Free Software available on Internet
* Source Code example for your favourite programming language.
