Actually, I need to control the baseline resistance and gas resistance at certain times by seconds to calculate the response time. Please see the provided image
If you plan on analyzing the variation of Rg over time, you need to accumulate a list of (Clock1.SystemTime, Rg) values.
I am unable to match your sketch variables Value_CH1 and Value_CH2 with any of your AI2 global variable names.
Is your sketch author on the same team as you?

Actually this is not my graph but this is the same as I have for my work for resistance variation over time
Here is a sample graph over time:
You need to get your two incoming data values onto one message, ending in \n, to assure they stay in sync.

I can't proceed further without a good explanation of those two quantities arriving from Bluetooth into the app, and what they represent.

Yes thanks tomorrow I will modify the app and check the Bluetooth after that I send here
Actually, thank you so much for your advice
From the ESP32 I will receive voltage that can be converted to resistance using math calculation wheatstone bridge so a the time using clock timer I can plot resistance versus time for gas sensing variation.
Since when is voltage two numbers preceded by a # sign?
And where in your blocks do you deal with the # sign?
