Question

我有两个特性，没有响应，一个带有描述符2902，另一个没有描述符。我想发送20个以上的字节，但终止时只写16个字节另一个是0100000等我正在使用以下代码。

void sendDataToBLE(String str) {
    str = "st,1544697039";

    Log.d(TAG, "Sending result=" + str+ " "+characteristicTX);
    final byte[] tx = str.getBytes();

    if (mConnected) {


        characteristicTX.setValue(tx);


        mBluetoothLeService.writeCharacteristic(characteristicTX);
        mBluetoothLeService.setCharacteristicNotification(characteristicRX, true);
        mBluetoothLeService.readCharacteristic(characteristicRX);

        }
}

下面是我的日志

如何增加字节数限制，以便将完整的数据发送到BLE设备？

我尝试使用代码增加MTU值，但没有增加MTU值

我们如何将大字节数据发送到BLE设备？
