Sending string commands from Python to a bluetooth device

Here's the same code, but with individual functions associated with each button:
All you have to do is add the interface code:

import tkinter as tk


class BtnEngine:
    # rename class as you wish
    def __init__(self, parent):
        self.parent = parent
        self.parent.title("Tryout7")
        self.parent.minsize(100, 100)

        self.btn_row = 0
        self.btn_column = 0
        self.number_of_btns = 12
        self.btns_per_row = 4
        self.btn_number = 0
        self.btns = [None] * self.number_of_btns

        self.dispatch()

    def dispatch(self):
        self.create_buttons()
    
    def create_buttons(self):
        btn_titles = ["volume up", "volume down", "channel up", "channel down", 
            "conditioner on", "conditioner off", "raise the bed ", "lower the bed",
            "open television", "mute", "open curtain", "close curtain"]

        btn_actions = [self.volume_up, self.volume_down, self.channel_up, self.channel_down,
            self.conditioner_on, self.conditioner_off, self.raise_the_bed, self.lower_the_bed,
            self.open_television, self.mute, self.open_curtain, self.close_curtain]

        while self.btn_number < self.number_of_btns:
            if not ((self.btn_column + 1)  % self.btns_per_row):
                self.btn_row += 1
                self.btn_column = 0

            self.btns[self.btn_number] = (tk.Button(self.parent, text=btn_titles[self.btn_number],
                padx=60, pady=20, height = 2, width = 5,
                command=lambda idx=self.btn_number, btitle=btn_titles[self.btn_number], 
                bfunc=btn_actions[self.btn_number]: self.button_clicked(bfunc, btitle, idx)))

            self.btns[self.btn_number].grid(row=self.btn_row, column=self.btn_column)
            self.btn_column += 1
            self.btn_number += 1

    def button_clicked(self, fcntn, title, idx):
        fcntn(idx+1, title)

    def volume_up(self, idx, title):
        print(f"Button {idx} pressed, {title} command running")
