UI cannot auto refesh when I use Serial binding

Hi all,
I use serial binding to receive/ send data from RF CC1101 connected Raspberry running Openhab 1.8.3 to CC1101 connected MSP430. I just receive data from CC1101 connected Raspberry and show Openhab successly, But I have a problem, I think that it is also important for user. My UI cannot auto refesh when I use Serial binding. UI only can auto refesh when I disable Serial binding. Please help me, It is difficult for me

Anyone can help me? Please

Please help me, again
