Question

我有这个代码来创建一个Advertise：

private void startLeAdvertise() {
        AdvertiseSettings settings = new AdvertiseSettings.Builder()
                .setAdvertiseMode(AdvertiseSettings.ADVERTISE_MODE_LOW_LATENCY)
                .setTxPowerLevel(AdvertiseSettings.ADVERTISE_TX_POWER_HIGH)
                .setConnectable(true)
                .setTimeout(ADVERTISE_TIMEOUT)
                .build();

        AdvertiseData data = new AdvertiseData.Builder()
                .addServiceUuid(new ParcelUuid(UUID.fromString(BEACON_SERVICE)))
                .build();

        mAdvertiseCallback = new AdvertiseCallback() {
            @Override
            public void onStartSuccess(AdvertiseSettings settingsInEffect) {
                super.onStartSuccess(settingsInEffect);
                Log.i(TAG, "======= onStartSuccess:");
                Log.i(TAG, settingsInEffect.toString());
            }

            @Override
            public void onStartFailure(int errorCode) {
                super.onStartFailure(errorCode);
                String description = "";
                if (errorCode == AdvertiseCallback.ADVERTISE_FAILED_FEATURE_UNSUPPORTED) {
                    description = "ADVERTISE_FAILED_FEATURE_UNSUPPORTED";
                } else if (errorCode == AdvertiseCallback.ADVERTISE_FAILED_TOO_MANY_ADVERTISERS) {
                    description = "ADVERTISE_FAILED_TOO_MANY_ADVERTISERS";
                } else if (errorCode == AdvertiseCallback.ADVERTISE_FAILED_ALREADY_STARTED) {
                    description = "ADVERTISE_FAILED_ALREADY_STARTED";
                } else if (errorCode == AdvertiseCallback.ADVERTISE_FAILED_DATA_TOO_LARGE) {
                    description = "ADVERTISE_FAILED_DATA_TOO_LARGE";
                } else if (errorCode == AdvertiseCallback.ADVERTISE_FAILED_INTERNAL_ERROR) {
                    description = "ADVERTISE_FAILED_INTERNAL_ERROR";
                } else {
                    description = "unknown";
                }
                Log.i(TAG, "error: " + description);
            }
        };
        mBluetoothLeAdvertiser = BluetoothAdapter.getDefaultAdapter().getBluetoothLeAdvertiser();
        mBluetoothLeAdvertiser.startAdvertising(settings, data, mAdvertiseCallback);
}

无论我总是得到什么

ADVERTISE_FAILED_TOO_MANY_ADVERTISERS

我正在测试 One Plus X（ONE E1003）
- API 5.1.1;
- 氧气2.2.0;
- 内核3.4.0-pref +;

Nexus 5
- API 6.0.1;
- 内核3.4.0-g7717f76;

（有趣的是，Nexus我得isMultipleAdvertisementSupported == false所以它也不起作用......）

编辑 - 使用此模型可以正常运行：

Galaxy S6（SM-G920F）
- API 5.1.1;
- 内核3.10.61-5816106;

我原来的问题是，为什么我总是得到ADVERTISE_FAILED_TOO_MANY_ADVERTISERS。既然我发现它适用于S6但不适用于Nexus 5我能想到什么？是制造商/硬件问题还是操作系统版本？谢谢。

Answer 1

在使用其他设备运行更多测试后，我发现这是实现它的正确方法，但它只适用于少数芯片组。有关此技术的更多信息，请访问：Chipsets/Devices supporting Android 5 BLE peripheral mode

BluetoothLeAdvertiser AdvertiseCallback抛出ADVERTISE_FAILED_TOO_MANY_ADVERTISERS
