// BLE 扫描（Android 4.3 ~ 14 兼容）
implementation “no.nordicsemi.android.support.v18:scanner:1.6.0”

// BLE 连接 / GATT / 读写 / Notify（核心）
implementation “no.nordicsemi.android:ble:2.10.2”

// Kotlin 协程支持（suspend / Flow）
implementation “no.nordicsemi.android:ble-ktx:2.10.2”

如果用到 下面的库可以选择依赖
// 只有老 LiveData 架构才要
implementation “no.nordicsemi.android:ble-livedata:2.10.2”

// 公共常量（通常会被 ble 自动传递）
implementation “no.nordicsemi.android:ble-common:2.10.2”

) : BleManager(context) {

override fun getGattCallback(): BleManagerGattCallback {
    return object : BleManagerGattCallback() {
        override fun onServicesDiscovered(device: BluetoothDevice, services: List<BluetoothGattService>) {
            // 找到你的 Service / Characteristic
