Can't receive back data telemetry #24

Hello, I try to redo your project with my drone DJI Tello. My computer uses Windows 10

-I have followed the explanations of the installation -I imported the flow solution "Receiving Tello Telemetry Data". -I opened port 8890 in the firewall -I connected the computer to the Wi-Fi of the drone

I can launch the drone and make it move but I can't receive telemetry information. This error is displayed in the debug and in the command prompt : [udp in:bd7e5975.45fad8] error: EACCES

Do you know how to fix this error so that I can access the telemetry information?

Hi @max051505 - Its been a while since I played with my Tello. Hopefully you're a winner from the IBM raffle?

I'm a Linux user so I'm not certain about Win10 firewall rules. I show the Linux firewall commands to receive telemetry data in Part5

From your screenshot, you might have too many Node-RED flow tabs listening to port? You might want to "Disable" all the flows except for the telemetry flow. Double click on the tab and at the bottom there is a button to Enable / Disable. Change the other tabs to Disabled and Deploy.

Thank you for your answer ! I tried to do as you told me but it still doesn't work. So I decided to use ubuntu :

But I've got a telemetry error again: error] [udp in:bd7e5975.45fad8] error: EADDRINUSE
