-===== -. The End-to-End Challenge =====
+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)
+}
+</code>
+===== -. Day One Challenges =====
+==== -. The End-to-End Challenge ====
+I can send data from the device to the application.
+==== -. The Downlink Challenge ====
+I can send data from the application to the device.
+==== -. The Radio Challenge ====
+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);
+</code>
+==== -. The Sensor Challenge ====
+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]]. The dashboard facility on emoncms is used to visualize the sensor data.
