Hi!
I'm experiencing an issue with my code that involves using Bluetooth client blocks to verify the connection when certain buttons are clicked. It doesn’t seem to be working, and I'm having trouble identifying the problem. As a beginner, I would also appreciate any suggestions to improve the code and make it simpler and more efficient.
Thanks in advance!

Blocks:
The issue happens when the buttons LED_toggle, Start, and Relay_"x"_toggle are pressed. It is supposed to verify if bluetooth is connected, but it still will proceed to showing next screen and I continue getting broken pipe errors whenever bluetooth isn't connected and I try to turn the LED's or the relay's on.
