BluetoothLeAdvertiser AdvertiseCallback 抛出 ADVERTISE_FAILED_TOO_MANY_ADVERTISERS

Question

我有创建广告的代码：

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);
}

无论什么我总是得到

ADVERTISE_FAILED_TOO_MANY_ADVERTISERS

我正在测试
一加X (ONE E1003)
- API 5.1.1;
- 氧气 2.2.0；
- 内核 3.4.0-pref+；

连结 5
-API6.0.1；
- 内核 3.4.0-g7717f76；

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

编辑 - 这个模型工作得很好：

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

我最初的问题是，为什么我总是得到 ADVERTISE_FAILED_TOO_MANY_ADVERTISERS。现在我发现它适用于 S6 但不适用于 Nexus 5 我可以假设什么？是 manufacturer/hardware 问题还是 OS 版本问题？谢谢。

在运行对其他设备进行更多测试后，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，请参见：Chipsets/Devices supporting Android 5 BLE peripheral mode
