<div class="markdown_content"><p>IDE:3.5.16.40 package:4.0.1 and IDE:3.5.16.0 package:3.5.16.20<br/> I used the Raspberry Pi 4B to control the EtherCAT servo. For the first time, I could control the normal communication. After disconnection, I could not scan the device<br/> All tests are like this. What is the problem? Thank you!</p></div>
