Writing on virtual pin from LabVIEW on Windows

Hi
I am trying to write on virtual pin from LabVIEW in order to see result on the ios Device through Blynk app. I am using TCP communication API in LabVIEW and sending data to Blynk cloud. I would really appreciate if somebody could help me.
First I send LOGIN cmd with authentication code and I am getting response code 200 which should be ok I hope.
Then I send HARDWARE command, message id, length of message and message “vw 0 1” . This should turn on LED widged on my iphone which is set to be V0. But it does not work.
Here is what I send out HEX

LOGIN > 02 00 00 00 20 65 63 33 33 32 63 31 31 30 65 37 34 36 36 61 39 62 39 39 39 36 38 62 38 37 66 34 36 63 33 34
HARDWARE > 14 00 00 00 06 76 77 20 30 20 31

If somebody could write here working hexadecimal sequence of this like I did then it will really help me
Thanks
