Reading with python, username and password text data from Nextion

[javed222]

Hello! I am trying to read in python, text data from nextion for validate user and password information. Pressing button b0.txt, send from t0.txt “hello”

In raspberry pi can see two messages:

1. Touch event
2. Message of data text from Nextion

How I can retrieve data text message in a variable with your python client? Thanks Javier

Hello. Simple. You register an event handler on a button. When the button is touched you do ‘val = await nextion.get(“t0.txt”)’

Second approach is right. One mistake: not ‘nextion’ but ‘client’ in your case and define it somewhere in the module level.

Thanks Jevgeni!! just one doubt

I rename "nextion" to "client", but client is not declared yet... Please where i must declare client?

Thank you so much for everything Javier

Make this variable global. A search engine will help 😅
