Is it possible to write WirelessController commands to G1

[Rusteam]

I have adjusted WirelessController to G1, I can see that my code triggers ChannelSubscriber("rt/wirelesscontroller") but I don't see any action from the robot. My code is:

    ChannelFactoryInitialize(0, sys.argv[1])

    pub = ChannelPublisher("rt/wirelesscontroller", WirelessController_)
    pub.Init()
    smp = unitree_go_msg_dds__WirelessController_()

    smp.ly = 0.5
    for i in range(100):
        pub.Write(smp, timeout=1.0)
        time.sleep(0.01)

    smp.ly = 0
    pub.Write(smp)
    pub.Close()
