Overview for BluetoothSubscriptionException

Description​

BluetoothSubscriptionException is a custom exception that is thrown when an error occurs while attempting to subscribe to notifications or indications from a Bluetooth Low Energy (BLE) characteristic. This type of exception is particularly useful for handling the intricacies of BLE communication where setting up notifications or indications can fail due to a range of issues, such as connection instability, incorrect characteristic properties, insufficient permissions, or unsupported operations by the BLE peripheral.

The [message] field is intended to provide a more detailed description of the error, often including specific error codes or additional context provided by the BLE framework or the underlying platform.

Example​

try {
  // Code to subscribe to a BLE characteristic for notifications or indications
} on BluetoothSubscriptionException catch (e) {
  // Handle the exception by possibly retrying or notifying the user
  print(e);
}
