Esp32. tft screen and bluetooth problem

Other Hardware Displays
1

Hello everyone! I will summarize my project. I am working on a project that involves a TFT screen to graph data while from an application I can send certain orders. Also, with a specific command (sent from the cell phone) I can stop graphing data on the TFT screen and start graphing it on my cell phone (And the TFT screen stops updating).

The problem is that if I want to connect to the ESP32 via Bluetooth while the TFT screen is graphing, THE CONNECTION IS IMPOSSIBLE!. However, by modifying the code so that it is in "Send data via Bluetooth and not occupy the TFT screen" mode, the connection with the ESP32 via Bluetooth IS POSSIBLE!

My question is, what is the reason why this is happening? Does the TFT screen and Bluetooth share a pin internally?
Attached image of how the TFT screen is connected.

I would really appreciate if someone can tell me a possible solution.

The Fritzing diagram is uninterpretable and useless, as pins and connections are not clearly labeled. Please post a hand drawn diagram (pencil and paper is preferred), clearly labeling all pins and connection points.

Please post the code, using code tags.

However, by modifying the code

Explain and post the modifications.

Instructions and suggestions are in the "How to get the best out of this forum" post.
