Automatically accept pair request from certain devices

Brainstorm
1

I would like to be able to pair my laptop and my phone without having to manually accept the pair request on my phone. Is this possible?

2

Once paired, it should not unpair at all. I paired my phone just once, then I made a script which will connect/disconnect it (I have another to switch from discrete channels to quadrophonic/stereo, so I press both to listen to podcasts).

#!/bin/bash
# For toggling A15 Bluetooth connection with KDE Plasma notifications

DEVICE_MAC="08:A5:DF:D7:41:36"
DEVICE_NAME="Samsung A15"
CONNECT_SOUND="/home/ben/Audio/Sounds/phone-connect.ogg"
DISCONNECT_SOUND="/home/ben/Audio/Sounds/phone-disconnect.ogg"

# Function to get the current system volume
get_current_volume() {
    amixer get Master | grep -oP '\[\d+%\]' | head -n 1 | tr -d '[]%'
}

# Function to show KDE notification
notify() {
    local title="$1"
    local message="$2"
    notify-send -u normal -i "audio-volume-high" "$title" "$message"
}

# Function to check if the device is connected
is_device_connected() {
    bluetoothctl info "$DEVICE_MAC" | grep -q "Connected: yes"
}

# Function to show KDE notification and play sound
notify() {
    local title="$1"
    local message="$2"
    local sound="$3"

    # Show KDE notification
    notify-send -u normal -i "bluetooth" "$title" "$message"

    # Play sound if available
    if [ -f "$sound" ]; then
        paplay "$sound" &
    fi
}

# Main script
if is_device_connected; then
    echo "Device $DEVICE_NAME ($DEVICE_MAC) is connected. Disconnecting..."
    disconnect_output=$(bluetoothctl disconnect "$DEVICE_MAC" 2>&1)

    if ! is_device_connected; then
        echo "Successfully disconnected."
        notify "Bluetooth Disconnected" "Samsung A15 was disconnected" "$DISCONNECT_SOUND"
    else
        echo "Failed to disconnect: $disconnect_output" >&2
        notify "Bluetooth Error" "Failed to disconnect Samsung A15 $DEVICE_NAME ($DEVICE_MAC)" "$DISCONNECT_SOUND"
        exit 1
    fi
else
    echo "Device $DEVICE_NAME ($DEVICE_MAC) is not connected. Attempting to connect..."
    notify "Bluetooth" "$DEVICE_NAME ($DEVICE_MAC) is not connected... Attempting to connect!" "$DISCONNECT_SOUND"

    # Ensure Bluetooth is powered on
    bluetoothctl power on >/dev/null 2>&1

    # Try to connect
    connect_output=$(bluetoothctl connect "$DEVICE_MAC" 2>&1)

    if is_device_connected; then
        # Get current volume
        current_volume=$(get_current_volume)

        # Get current volume
        current_volume=$(get_current_volume)

        # Set volume to 45%
        amixer set Master 45%

        # Send a single notification with the current and new volume levels
        notify "Volume Adjusted" "from $current_volume% to 45%."

        echo "Successfully connected."
        notify "Bluetooth Connected" "Samsung A15 was connected" "$CONNECT_SOUND"
    else
        echo "Failed to connect: $connect_output" >&2
        notify "Bluetooth Error" "Failed to connect to $DEVICE_NAME ($DEVICE_MAC)" "$DISCONNECT_SOUND"
        exit 1
    fi
fi

exit 0

Then when I am taking my phone out of the room, I just hit the shortcuts again to return audio to the phone.
