Listen on UDP socket
https://www.hacksparrow.com/node-js-udp-server-and-client-example.html
Two udp listener needed: one to listen to all fligh commands a second one to listen to response to state commands
What is the best software architecture to implement this?
First I'll remove the setReceive function. Could make it much simpler.
After removig setReceived I've implemented a second udp listener. Seems to work. Now a second repeater is required to test the respons behaviour. Require is now a dictionary in repeater.js to send response to the correct listener.
Using experimental extensions in Scratch2 require nodejs installed.
If not already installed first install nodejs on your Raspberry PI.
Check if nodejs is installed?
$ node -v v8.11.1
or any other release.
In case nodejs is not installed.
$ node -v bash: node: command not found
Install nodejs:
$ sudo apt install -y nodejs
To install using this method, while holding the Shift key on your keyboard, click on the File menu choice at the top of the Scratch 2 window. Select Import Experimental Extension and you will be prompted for a URL to load the file.
You need to supply the full path and file name of the JavaScript extension for the URL.
The path and file I'm using is:
/home/pi/code/TelloforScratch/Tello.js
Please use your own path!
