Fix BleGattCannotStartException

in React Native

Solution

The BleGattCannotStartException in React Native BLE implementations typically arises from issues with Bluetooth adapter state or rapid connection attempts without proper cleanup. To resolve this, ensure Bluetooth is properly enabled and initialized before any connections, and implement a delay or cancellation mechanism between connection attempts to avoid overwhelming the Bluetooth stack, giving it time to properly shut down the last try. If using `react-native-ble-plx`, explicitly disconnect and destroy the BleManager when the component unmounts or the bluetooth connection is no longer needed by setting the `autoDestroy` property to `true` to handle resource management automatically.
