-===== -. The Challenges =====
+If you need to send data to your device, you should publish the encoded message in the corresponding topic ''application/APPLICATION_ID/node/DEVICE_EUI/tx'' as follows:
+<code>
+{
+    "reference": "abcd1234",                  // reference which will be used on ack or error (this can be a random string)
+    "confirmed": false,                        // whether the payload must be sent as confirmed data down or not
+    "fPort": 10,                              // FPort to use (must be > 0)
+    "data": "...."                            // base64 encoded data (plaintext, will be encrypted by LoRa Server)
+}

 I can tune the LoRa radio parameters and assess the results.
+These two commands can be helpful when used after the join event:
+<code c++>
+LMIC_disableChannel(N);
+LMIC_setDrTxpow(DR_SF12,14);

 ==== -. The Sensor Challenge ====
-I can use different sensors to send data from the device.
+I can use different sensors to send data from the device: PIR, moisture, temperature, light, etc.
+===== -. Day Two Challenges =====
+==== -. The Wind Rises ====
+This is a mandatory challenge. It consists of using [[https://nodered.org|Node-RED]] to receive data from the sensors (via MQTT) and send it to [[https://emoncms.org|emoncms]] for visualization.
+^ Provided material ^
+| VM with Node-RED installed |
+| Node-RED example flow |
+| [[https://emoncms.org/dashboard/view&id=37655|Dashboard example]] |
+^ Required skills ^
+| Basic javascript |
+| GUI configuration |
+| Two drops of IoT design |
+==== -. Nausicaa Challenge ====
+You have to take control on the devices. Use some scripting to send commands and do some actions or tune some parameters on the devices.
+^ Required skills ^
+| Basic scripting (for example python) |
+| Basic electronics |
+| Two drops of IoT autocracy |
+==== -. Totoro Challenge ====
+You have to store the sensor data in a database. Use Node-RED to inject data in a (influx) database.
+^ Required skills ^
+| Basic database |
+| Two drops of IoT resilience |
+==== -. Kiki Challenge ====
+You have to implement a radio coverage test on the campus.
+^ Required skills ^
+| Basic scripting |
+| Two drops of IoT ubiquity |
+==== -. Mononoke Challenge ====
+You have to implement a chat bot designed for working with Google Hangouts. The bot answers requests and reveals sensors data.
+^ Required skills ^
+| Basic scripting with python |
+| Two drops of IoT robot attitude |
