Hi Bowei
I have hundreds of different buttons and functions that work fine. The problem is only when I have more than 3 edit type widgets set to input_type: int on one page/window. When the page loads it sends cmd lines you see above. When it exceeds the 200 bytes it becomes truncated or the HMI is timing out.
Since I can increase the [RX_LEN] to 300, 400 ,500 and it does nothing to fix the problem I am assuming the the internal transmission buffer of the HMI is only 200 bytes.
Best Regards
