BluetoothConnectionException class

Exception for handling errors during the BLE peripheral connection process.

This exception is thrown when an attempt to connect to a Bluetooth Low Energy (BLE) peripheral fails or encounters a problem. Establishing a connection is the first step in BLE communication, which enables further interactions such as service discovery, reading, and writing characteristic values.

The BluetoothConnectionException carries a message that provides more information about the failure, which can be valuable for troubleshooting or informing the user about what went wrong.

Example

Here's how to handle a BluetoothConnectionException:

try {
  // Attempt to connect to a BLE peripheral
} on BluetoothConnectionException catch (e) {
  // Respond to the connection error, perhaps by notifying the user or attempting a reconnect
  print(e.message);
}
