Fix CannotMonitorCharacteristicException

✅ Solution

The "CannotMonitorCharacteristicException" in react-native-ble-plx usually occurs because the Bluetooth characteristic you are trying to monitor (using `monitorCharacteristicForService`) does not have the "notify" or "indicate" properties enabled. To fix this, ensure that the Bluetooth device's GATT server is configured to allow notifications or indications for the characteristic, and verify in your code that you are correctly identifying the characteristic UUID with either notify or indicate properties. You may need to explore and understand the GATT structure of your device.
