You are using many logical issues and make the dc to freeze. The was how handled the list picking is not good. You set before picking, timer enabled true. Think alternate logic to make the timer to trigger

Second one you have not handled the block properly. See the red mark also nothing is mentioned in the variable. To avoid this pls use global variable

I've figure out the 2nd problem

is there a way that my BT connection run, receive data and store data smootly?

Do you want to run everytime or one time only?

hmm, I never thought of that. All I want for my project is

When it connects to bluetooth and receives data It'll change the text of the label
so I think I need it to constantly connected through out the process?

Ok then try line this

1. Button.Connect.Click
    BluetoothClient.Connect(address)

2. BluetoothClient.AfterConnecting
    set Clock.Enabled to true

3. Clock.Timer
    if BluetoothClient.IsConnected
        do
            set tempText to BluetoothClient.ReceiveText
            if tempText ≠ ""
                Label.Text to tempText

4. // When user clicks Connect button
when ButtonConnect.Click
    do
        BluetoothClient.Connect(address)  // or use a list picker for device selection

// After successful connection
when BluetoothClient.AfterConnecting
    do
        set Clock.Enabled to true

// When user clicks Disconnect button (if you have one)
when ButtonDisconnect.Click
    do
        BluetoothClient.Disconnect
        set Clock.Enabled to false
        set Label.Text to "Disconnected"


when Clock.Timer
    do
        if BluetoothClient.IsConnected
            do
                set tempText to BluetoothClient.ReceiveText
                if tempText ≠ ""
                    set Label.Text to tempText

Just got to ask that is the "Button.Connect" youre talking about is the "List Picker"?

maybe try this CompCreator extension, not that difficulty.
