<p dir="auto">I have a working application using UiFlow but there are a couple issues.<br />
#1 Occasionally I get a CRC error on the returned data. If the M5Stack is running directly off the hardware it will freeze. If I run it from UiFlow it will display the error. Is there a way to trap the error and ignore it if it's a CRC error?</p>
<p dir="auto">#2 Even though the sending and receiving data portion is only about 30-40ms the program is only looping through one per second. Is there a way to increase it to 3-4X per second or is that a limitation of the hardware and Python?</p>
