 +====== How to Setup the Object Detection Demo ======
 +
 +**Materials**:
 +  * Tello drone, ideally with multiples batteries
 +  * Jetson computer (Jetson Xavier NX is the current recommendation)
 +  * Screen, keyboard and mouse
 +  * Router
 +
 +===== Preparing Router =====
 +
 +In this case we are using the router [[https://www.asus.com/networking-iot-servers/wifi-routers/asus-wifi-routers/rt-ac51/ | ASUS model RT-AC51]]. You can get the manual from [[https://www.asus.com/us/supportonly/rt-ac51/helpdesk_manual/ | here]].
 +
 +Check your router manual and configure the **SSID** and **PASSWORD** to connect to the network. In our case all the information is in labels stuck physically on the router.
 +
 +===== Preparing Tello =====
 +
 +Background information: The drone can be in two possible connection modes:
 +  * **Station Mode:** \\ The drone is the Access Point. It creates its own Wi-Fi network and provides its own SSID. The client (the Jetson computer) connects to the drone's SSID directly.
 +  * **Access Point Mode:** \\ The drone connects to an existing Wi-Fi access point (AP, SSID) as a client. The Jetson connects to the same SSID.

 +
 +==== Set Mode using the Tello CLI ====
 +
 +  - Download and install the [[https://github.com/harleylara/tello-js | tello-js]] package. This package includes a ''CLI'' tool that allows you to configure the drone.
 +  - Reset the Tello's Wi-Fi to factory configuration. To do so **press and hold the power button for 5 seconds**, the drone will restart with default configuration (Station Mode, no password)
 +  - Connect to the drone's Wi-Fi
 +  - Open a terminal and type:
 +
 +<code>
 +tello set-ap -i
 +</code>
 +
 +This set the Tello drone in Access Point Mode, the argument ''-i'' start the setup in interactive mode, for more details of the ''CLI'' check the ''README.md'' file from the [[https://github.com/harleylara/tello-js | tello-js]] repo.
 +
 +
 +===== Setup Static IP Address for Tello Drones =====
 +
 +When the Tello drone is configured in **Access Point Mode** (more details in the next section) the DHCP server automatically assigns an IP on the network, this makes the __ IP of the drone unpredictable__ when connecting to it. To solve this problem you can assign a **static IP to the drone** so that each time it connects to the network it receives the same IP, that way if you have multiple drones on the network each one can have a static IP that identifies it.
 +
 +If you are using the router ASUS RT-AC51 **check the manual** in **section 4.2.2 DHCP Server** (item number 8). Note that configuring a static IP for a device on the network varies depending on the company or even the router model so check your router manual to perform this configuration.
 +
 +
 +===== Running the Demo =====
 +
 +<code>
 +cd ~/tello-controller-jetson
 +python3 main.py
 +</code>
 +
 +The source code is in github: [[https://github.com/eligosoftware/tello-controller-jetson| tello-controller-jetson ]]
