サムスンS7マシュマロで「ガットスタックに失敗しました」というエラーが表示されました。このシナリオでは、21個のBLEペリフェラル（nrf52）で作業しています。私は利用可能なデバイスをスキャンし、次にデバイスを接続する=>書き込みデータ=>デバイスを1つずつ切断します。何度か試してみると、このエラーが出ます。私がアプリケーションが存在すれば、それは元に戻ります。助けてください！gattスタックに登録できませんでしたエラーBLE androidサムスン
既にお試しください：すべてのconnectGatt、disconnectGattメソッドのメインUIスレッドに書き込みます。私は質問が重複していることを知っている GATT callback fails to register on stackoverflow。しかし、それは私のために働いていません。
これは私の主な活動でコード
public boolean connect(final String address) {
if (mBluetoothAdapter == null || address == null) {
Log.w(TAG, "BluetoothAdapter not initialized or unspecified address.");
return false;
}
// Previously connected device. Try to reconnect.
if (mBluetoothDeviceAddress != null && address.equals(mBluetoothDeviceAddress)
&& mBluetoothGatt != null) {
Log.d(TAG, "Trying to use an existing mBluetoothGatt for connection.");
if (mBluetoothGatt.connect()) {
mConnectionState = STATE_CONNECTING;
return true;
} else {
return false;
}
}
final BluetoothDevice device = mBluetoothAdapter.getRemoteDevice(address);
if (device == null) {
Log.w(TAG, "Device not found. Unable to connect.");
return false;
}
// We want to directly connect to the device, so we are setting the autoConnect
// parameter to false.
mBluetoothGatt = device.connectGatt(this,false, mGattCallback);
Log.d(TAG, "Trying to create a new connection.");
mBluetoothDeviceAddress = address;
mConnectionState = STATE_CONNECTING;
return true;
}
public void disconnect() {
if (mBluetoothAdapter == null || mBluetoothGatt == null) {
Log.w(TAG, "BluetoothAdapter not initialized");
return;
}
Handler handler = new Handler(Looper.getMainLooper());
handler.post(new Runnable() {
@Override
public void run() {
mBluetoothGatt.disconnect();
}
});
}
public void close() {
if (mBluetoothGatt == null) {
return;
}
Log.w(TAG, "mBluetoothGatt closed");
mBluetoothDeviceAddress = null;
mBluetoothGatt.close();
mBluetoothGatt = null;
}

このエラーを引き起こすコードを送って、メインスレッドでこれを行うべきではなく、intentserviceまたはasynctaskを代わりに使用してください。 –
@Mehran Zamani私は質問を編集しました –
あなたは 'public boolean connect（final String address）'をどこで呼びますか？ –
