 Before we start, you have to do the following:
-- Form teams and give them cool names
+- Form a team of **THREE**
-- Give us the infos (team names, members' names & emails)
+- Give us the infos (team number, members' names & emails)
-Only after validating your team you will be able to access the challenge.
-Why do we need your email? Well, the winning team members will receive a **USRP device**, kindly given by our partner National Instruments. A "Certificate of Success" will be given too.
+Why do we need your email? Well, the winning team members will receive a SigFox device and one **USRP device**, kindly given by our partners SigFox and National Instruments.
 To verify your progress, there will be several checkpoints to be __**validated by one of the organizers**__ (Leo, Matthieu, Othmane, Cyrille, Pascal, Tanguy ...).

 The goal is familiarize with the [[https://project.inria.fr/ephyl/|EPHYL Project]] GNU Radio framework, understand it, and try some stuffs.
+**REMINDER**: If you you have never used GNU Radio Companion (GRC), it is **HIGHLY** suggested that you go check some [[tutorials|tutorials]]. Especially Tutorial **3** and **6**

+Start experimenting and try to get some results as in the local tests.
+Maybe you'll have to strengthen the processing in the uplink transmission (modify some parameters, thresholds, etc)
-Start your experiment and evaluate the transmission quality.
+**UPDATE For Wednesday 21 :**
-Maybe you'll have to strengthen the processing in the uplink transmission !
+If you have some difficulties creating GRC flowgraphs, you can get an example for each node here:

+yourlogin@srvairlock:~$ cp /cortexlab/homes/ooubejja/ws/cxlb stage2/
+yourlogin@srvairlock:~$ ls stage2/cxlb

+Open ''main_bs.grc'' and ''main_sensor.grc'' in GNU Radio, some parameters are already set to match CorteXlab setting (UHD blocks, generation options, reference source,etc). However, you should verify RF parameters (Freq, gain, sample rate,etc).
