i was working on a ble application that worked well 100%,I stopped to buy some hardware that was missing but now it doesn't work anymore, check and i saw that i have blocks that no longer have the bluetoothble extension and others new appear like the simple block: call BluetoothLE.connect that asks for (for component)and (index), data that I don't know what they are... others like (devise) too. I appreciate your help
