Hello friends,
is anyone here working with this gadget?
https://www.sensirion.com/de/umweltsensoren/feuchtesensoren/development-kit/

I try to integrate it via B4A, but can't get it right.
I mainly miss the entries from the
Sub Manager Connected
and Sub Manager_DataAvailable
So someone can help?

The info you have provided is not gonna help you much. Its impossible to guess that does those subs are for without reading the documentation. You should post your code or project along with much information that will help other members to understand.

That's my code right now.
I just don't know how to get directly to the temperature and humidity data.

So where did you called scan function?

Wolli013 · Sep 20, 2019

CallSub(Starter, "Scan")

Add a log(id) before

If Id = "E6:8F

7:A1:10:81" Then

to check if that event is getting fired or not.
