No reliable write support

Please include reliable write support for this library as I cannot see it anywhere

BleManager.getInstance().connect(bleDevice, new BleGattCallback() { @Override public void onConnectSuccess(BleDevice bleDevice, BluetoothGatt gatt, int status) {

//I'm connected here. Find your data service and channel according to your Bluetooth protocol String uuid = context.getInfo().cmut_uuid;//Server data String uuid_w = context.getInfo().cmut_uuid_w;//Server data String uuid_n = context.getInfo().cmut_uuid_r;//Server data

App.UUID_SERVICE = gatt.getService(UUID.fromString(uuid));
                UUID_SERVICE = App.UUID_SERVICE;

                App.UUID_WRITE = App.UUID_SERVICE.getCharacteristic(UUID.fromString(uuid_w));

I want to get response data from ble when I write to ble device and get device response data on OnWriteSuccess. How this gonna help me in that situation? Can you explain further?

蓝牙数据发送时可以根据boolean值得知发送成功失败,但是得到返回是回调函数,如果你想同步处理就要先主线程沉睡,因为返回值是异步的 When sending Bluetooth data, you can know the success or failure of sending according to the Boolean value, but the return function is the callback function. If you want to synchronize, you need to sleep the main thread first, because the return value is asynchronous
