As mentioned earlier, our Tello's do not have GPS so when we say "20 cm" it's kind of a guess.
Let's get our bearings before we start creating our first programs.
How it works
We need to be very clear on how our Drone and how our App work together… but separately.
Tello Wireless / WI-FI (this is the Wi-Fi the Tello Drone creates)
Staff / Teachers / Home WI-FI (this is your home / school Wi-Fi)
Order of Wireless on Laptop / Apple / Android Device
1. Connect to School Wireless
2. Open DroneBlocks App
3. Login
4. Download projects / missions
5. Disconnect from School Wireless
6. Connect to Tello Wireless
7. Launch Mission
8. Tweak Code
9. Repeat 7 + 8 unless finished
10. Disconnect from Tello Wireless
11. Connect to School Wireless
12. Save your Mission
Status Lights
Looking closely at our Tello you can see a tiny little LED. This LED lets us know the state / status of our Drone.
Off - haha, this means … it's off.
Cycling red, green, orange = booting up.
Flashing orange = waiting for Wireless Connection.
Blinking Green = good sign, Visual Positioning System is active and working.
Blinking Orange = bad sign, VPS not active, controlling drone is going to be an issue.
