Hi Guys, thank you for your friendly feedback!
ABG : in mastr_ip is just the address of the Raspberry in the local network (it is running a simple http.server): 192.168.4.1:8080, which can also be reached by the app.
@ChrisWard
You are right, I just kept that errorhandling from a previous app and don't remember it's purpose anymore but the 1109 error is never called, just checking this post as a reference:
Here is what Timer1 is doing:
It sends a query to the http.server each 3000ms and stores the values from the received list into two variables, people_inside and max_people.
@TIMAI2
Thank you for the nice comment, where I learnt sth. practical, I've connected my WIN10 Laptop to the network and sent a GET request as follows:
http://192.168.4.1:8080/people_inside-10
in firefox
The python code processes it nicely without an error but I think Firefox is getting an error: Connection interrupted
It is a different error than if I try to access Google without internet connection because there it says check your internet connection Network timeout:
One option would be that I simply ignore the error message 1101 in AI2. I think I can still work an app that fits my needs since the problem is really only that I receive an unnecessary error message rather than an actual crash occurs.
Btw.: I have also tried using windows CMD and telnet:
telnet 192.168.4.1 8080
GET people_inside-10
GET /people_inside-10
tried a few but I am not finding the right syntax.
