Installation

To use this package, add l2cap_ble as a dependency in your pubspec.yaml file:

dependencies:
  l2cap_ble: ^latest_version

Usage

Scan for Bluetooth Devices: Use your preferred Bluetooth scanning package to find and obtain the deviceId of the target device.

Initialize L2CAP Communication:

final ble = L2capBle();

Monitor Connection State:

Subscribe to the connection state stream to track L2CAP connection progress.

final connectionStream = ble.getConnectionState();

Connect to Device:

Establish a connection to the device using connectToDevice, and await the 'connected' state.

await ble.connectToDevice(deviceId);

Create L2CAP Channel:

Use createL2capChannel to establish the L2CAP channel, providing the required psm.

final channelCreated = await ble.createL2capChannel(psm);

Exchange Messages:

Send and receive messages seamlessly via the L2CAP channel with sendMessage.

final response = await ble.sendMessage(myMessage);

Disconnect Gracefully:

Disconnect using disconnectFromDevice. The L2CAP channel closes automatically.

ble.disconnectFromDevice(deviceId);
