Update Slider position via bluetooth

Hello everyone, everything good?

I control two motors using two slider bars and each one sends a combination of values, for example: v + 50 (number represents the speed that varies from 0 to 255). And also in the other slider bar it sends the combination of: b + 60 (example of speed).

But I want to reconnect to the bluetooth the slider bar update with the last value saved on the Arduino.

can you help me?

Assuming you've saved the value on the Arduino side, you would need to set up your code so that when you reconnect it reports the saved values to your app. Once you've got those values, you can set the slider position in the blocks.

I'm sharing images of what the current code looks like.
In this case, I'm failing to update the Slider's position.

On arduino I'm saving data.

When I launch the application, it sends a text message containing a letter "u" to check for updates ....

Hence the receipt "arduino x application" and Slider update.

I can not understand.Capture Capture2 Capture3
