ConnectionPool class

A class to manage connection pool settings for BLE devices.

Connection Pooling enables the exclusive connection of scanners to devices by using a 4-character hexadecimal ID. This ensures automatic and secure connections, especially in environments where multiple scanners are used across different devices.

This class allows setting and resetting the connection pool ID, validating hex IDs, and generating the corresponding QR data for a connection pool.

Example usage:

• Use setHexId to set a specific hex ID for the device.
• Use resetHexId to reset the device's connection pool ID to the default '0000'.
• Use getConnectionPoolQRData to generate QR code data based on the current connection pool ID.

Properties

hashCode → int

The hash code for this object.

no setter, inherited

reservedHexIds → List<String>

A list of reserved 4-character hexadecimal IDs that cannot be used for connection pooling.

final

runtimeType → Type

A representation of the runtime type of the object.

Methods

getConnectionPoolQRData(String poolId) → String

Generates a configuration command string that can be encoded into a QR code. The QR code data contains the necessary information to configure the device with the provided connection pool ID when scanned.

isValidHexId(String poolId) → bool

Checks if the given ID is a valid 4-character hexadecimal value.

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

resetHexId(String deviceId) → Future<CommandResponse>

Sends the reset command to the device, which reverts the connection pool ID to the default ('0000').

sendCommand(String deviceId, String command, {List<String> parameters = const [], bool sendFeedback = true}) → Future<CommandResponse>

inherited

setHexId({required dynamic deviceId, required String poolId}) → Future<CommandResponse>

Sets the connection pool ID to the specified 4-character hexadecimal value.

toString() → String

A string representation of this object.

Operators

operator ==(Object other) → bool

The equality operator.
