lack of communication between my app and esp32.

Good day to you all. It is nice to be amongst great minds who are making changes out here. Please I need assistance in rectifying a problem i Encountered while developing an application to help communicate with a display board. The Bluetooth will scan for nearby devices and display them however when I click to connect it just load for a moment and return an error message i integrate in the notifier. I will attach a screenshot of my block build up i would appreciate it anybody can help analyse it and offer me guidance on where and what to adjust.
Thank you.
