在Android中,BLE广告失败的错误代码1通常表示ADVERTISE_FAILED_INTERNAL_ERROR,表示因为内部错误导致广告失败。以下是一个示例解决方法:
private BluetoothLeAdvertiser mBluetoothLeAdvertiser;
private AdvertiseCallback mAdvertiseCallback;
// 初始化BLE广告
private void initBLEAdvertising() {
BluetoothManager bluetoothManager = (BluetoothManager) getSystemService(Context.BLUETOOTH_SERVICE);
BluetoothAdapter bluetoothAdapter = bluetoothManager.getAdapter();
mBluetoothLeAdvertiser = bluetoothAdapter.getBluetoothLeAdvertiser();
}
// 开始BLE广告
private void startBLEAdvertising() {
if (mBluetoothLeAdvertiser == null) {
Log.e(TAG, "BluetoothLeAdvertiser is null");
return;
}
AdvertiseSettings settings = new AdvertiseSettings.Builder()
.setAdvertiseMode(AdvertiseSettings.ADVERTISE_MODE_LOW_LATENCY)
.setConnectable(false)
.setTimeout(0)
.setTxPowerLevel(AdvertiseSettings.ADVERTISE_TX_POWER_HIGH)
.build();
AdvertiseData data = new AdvertiseData.Builder()
.setIncludeDeviceName(true)
.build();
mAdvertiseCallback = new AdvertiseCallback() {
@Override
public void onStartSuccess(AdvertiseSettings settingsInEffect) {
Log.d(TAG, "BLE advertisement started successfully");
}
@Override
public void onStartFailure(int errorCode) {
Log.e(TAG, "BLE advertisement failed with error code: " + errorCode);
}
};
mBluetoothLeAdvertiser.startAdvertising(settings, data, mAdvertiseCallback);
}
// 停止BLE广告
private void stopBLEAdvertising() {
if (mBluetoothLeAdvertiser == null) {
Log.e(TAG, "BluetoothLeAdvertiser is null");
return;
}
if (mAdvertiseCallback != null) {
mBluetoothLeAdvertiser.stopAdvertising(mAdvertiseCallback);
mAdvertiseCallback = null;
}
}
在使用上述代码时,确保已经获取了适当的权限,如BLUETOOTH
和BLUETOOTH_ADMIN
。此外,还需要检查设备是否支持BLE广告功能。
