Getting Unknown UART command

[devhari]

Hi,

I'm working on the wireless dimmer knob. when I sent 55 AA 02 00 01 01 00 00 03,
55 AA 02 00 03 02 00 01 00 07 commands through USART_Tx function I got RX commands properly from knob. After this two commands I'm transmitting button configuration Tx commands. But after sometime my knob giving unknown commands.
help me to find reason for getting this unknown commands.
55 AA 02 00 01 06 00 08 01 02 00 04 00 00 00 60 77
55 AA 02 00 02 06 00 08 01 02 00 04 00 00 00 60 78
55 AA 02 00 03 06 00 08 01 02 00 04 00 00 00 60 79
When I get this commands again if I rotate knob, I'm getting level values from zero onwards.

Thanks
